I do not routinely comment on TH-cam videos, but I am compelled to comment there to THANK YOU for finally solving what has been driving me absolutely crazy for the last 3 weeks. I fully rebuilt / replaced the carb and engine coil on my 13 year old PB-250. Started great, but bogged endlessly and never had consistent power. THEN is just started dying whenever I hit the throttle. I had this thing apart more times that J.Lo has been divorced, and as of yesterday was ready to throw in the towel and buy a new one. I found this video in a last ditch effort to save her, and within about 75 seconds, it's running like BRAND NEW again. Why was there no mention of this small set screw in ANY of the Carb instructions or Carb replacement videos??? Thank you for saving me hundreds of dollars and saving my perfectly good blower from a landfill!
Dude. I was extremely skeptical. I followed your instructions exactly and every single thing you said was true. The plastic plug came right out to my surprise. I turned the screw to the left and it ran like a top. Thanks so much. Saved me a trip to the small engine repair shop.
I was looking for a lightweight blower for my deck. th-cam.com/users/postUgkxgioZQl3J5wPGAeDINzbieKbT5qomSEx3 There are some huge trees around my house and the leaves and pods drop all over my deck. Having to move furniture around to sweep has become too big a chore. This blower was the answer. It is light enough for this 70yr old lady and powerful enough to blow all the tree droppings off my rather large deck. Thank you B&D. Be aware the cord is not included. I use a 3 prong outdoor cord 25' cord for my 12' x 20' deck. The cord retainer works very well, but don't try to pass the plug through it. That is NOT how it works. You just have to loop the cord and it works great. One of my best purchases. Very happy.
I see that your video was posted up 5 years ago. Today, it really did help me. My echo had been doing the same thing and that's because I had just picked it up from a repair shop. The man that repaired it, told me that the leaf blower was just too old. He had replaced carburetor, but the issue was bogging down. Because he had already replaced the carburetor, the rubber piece you use to heat up wasn't there making my repair extremely easy. I followed your instructions while pressing the trigger and wow, the leaf blower runs like new. Thank you so much for this video
Thank you for the great tip/procedure! Also, for anyone who does not have the right tools: I didn't have the right size punch but a 5/64" allen wrench heated with a cig lighter worked well.
That was one of the best you tube videos I have seen in a long time even though I don’t have that particular issue. The videography especially the close ups were on point, and the audio was clear. Subscribed. Thanks.
Brilliant! Followed your instructions and it worked wonderfully. I ended up clamping an allen wrench to a vise grip, heated up the wrench, stuck it down into the opening, waited a couple of minutes and popped that baby right out. Thanks so much for the great words of wisdom.
Used a 3/32 punch (slightly round at the end is all I could find) and my cigar lighter, warmed the end of the punch up, and stuck the punch in the plastic whole, small sizzle and smoke, and after 2 minutes pulled that sucker out like a charm...Thank you! Now just waiting on the replacement coil to install to start my Echo PB 250 LN up again, and use a small screwdriver to adjust the carb.
Getting mine ready for summer use and it wouldn't start. Took the carb all apart and cleaned it, cleaned the exhaust and still wouldn't start. Got good spark, fresh fuel, watched your video and adjusted the carb like you showed and BAM!!!! Started first pull, run wide open and fine tuned it. Runs better than last year for sure, thank you!
I was about to order a new carburetor. I bought the same leaf blower off of my neighbor for $20 dollars yesterday but it was doing the same thing. I adjusted the mix screw and it worked perfectly! Just had to turn it counter clockwise about 1 turn and a half. The little Plastic cover part of the screw was aggravating to get out so I just drilled it. Thank you so much!
BRILLIANT. We have two of these in the family and both run too lean. They always start right up fine when it’s cold. BUTTT😡 then I have to play 1/4 choke games for 20 seconds to keep it running or it dies. Then it will finally run full throttle . Trouble is both of them are obviously not running anywhere near what should be full throttle ever. I can’t wait to give this a try. Thanks a million!!
Thanks a million! My pb255 hasn’t run in a year. I’d replaced all seals, gaskets, bulb, lines, filters, spark plug and it wouldnt fill the primer bulb in 2019 but after all that it still wouldn’t run. Out of utter necessity I decided to give it another try again today. The primer bulb wouldn’t fill so the blower would only run for a short spurt and then shut off. I had the fuel lines to the carb backwards!Fixed that, it would run but would bog under load like your video shows. Thank goodness I found your video! I used the torch method to remove the black plug as you showed. Used the end of a small broken piece of a needle file I had laying around. I leaned out the mixture screw by turning counter clockwise just until it would run smooth at high rpm, not bog, had good transient throttle response and didnt smell dry, run too hot or sound like it was running lean. Kudos to you! This video got my tool up and running again. Many thanks. 🙏
this technique worked perfectly. My 13 year old son and I worked on ours… used a grill lighter and did not need a blow torch. Used a small Allen wrench. Amazing!
My leaf blower has been bogging like this nearly since the day I bought it and got it out of the box. Thank you for making this video. By the way, a hook pick will pull that plug out too.
My father gave me this leaf blower right after he bought it because he didn’t like how it ran and I told him the carburetor just needed tweaking. I knew where the screw was but I was wondering why did they put a plug there. I think I can use an easy out to get it out. Nice video. 👍🏻
yea a easy out would probably work. I think they put the plug there for emmisions reasons... but then when there's a problem like this, they don't want you to adjust it. This fix won't fix it every time.. but it will a lot of the times...
Take a Bath Productions - yeah I’m just curious if this may have been set up at a different altitude and living up here in the north eastern part of America throws it off a good bit.
It's for emissions and for the idiots who adjust it improperly and destroy the engine (that way they have more evidence of improper modification in case of a warranty claim).
I wanted to use my echo to blow snow off my sidewalk but it didn’t have enough power to move it. I watch your video and it fixed my low power. I didn’t have a 3/32, punch so I ground the tip off a nail and used it with a pair of vise grips, worked flawlessly! Great Video
Thanks for the video! My blower would start, but then bogged down and cut off. After I drilled out the black plastic nub, I turned the screw counterclockwise 1/2 to 1 revolution, and then it didn't choke down any more. Saved me from having to buy another blower. Thanks again.
Thank you thank you thank you! I was getting half power and thought it just needed to warm up... Nope adjustment solved my issues. I was getting half power and now she BLOWS!! Allen wrench instead of a punch worked great as well to remove the plug!! Sir i really cant thank you enough on this one!
I LOVE YOU MAN! THat worked perfectly. The only hard part eas digging out that plug. I didn’t want to sacrifice a craftsmannpunch’s temper. I got it out with a 1” drywall screw in about 3 minutes.
Had same problem after installing a new carb, fuel lines, s plug, air filter... Watched this video and luckily my new carb didn't have that plug to remove. Just gave it throttle and turned it counterclockwise and is ALOT better. This video helped no doubt.
Worked perfectly. I can now resume being the mad blower! I found a coarse screw turned into plastic cap worked as a puller, no problem. I think the screw vibrates out of tune with use as I needed to re-adjust every few blows.
Yes that'll work great.. and you could be right about the vibration.. You could take that screw completely out and put a drop of lock tight on the threads, screw it back in and adjust it properly, then it should stay.. But then you'll have a hard time adjusting it again if atmospheric changes causes it to need adjusted again, so I don't really recommend it, but it's an idea.
I had this same problem on my PB250 but this " fix " was not the issue . My exhaust port was almost blocked by carbon. I cleaned this port and the PB250 is brand new again. Just like it says in the Owners manual. I have been told it is due to cheap oil and gas .Thanks
Excellent. Yes I am aware of the spark arrestor in the muffler causing issues sometimes. I wish I would have mentioned that in the video as a possible culprit..
GREAT JOB! Same thing happened to me. Son tried to start the blower without the switch tuned to "ON" position so when I started the blower it almost sounded like a fouled plug. Replaced plug and same thing. Almost went to the Depot and picked up a new one but decided to google the problem and low and behold, I found you. The tip about putting a heated punch in the plastic plug is AWESOME. I don't think I would have been able to pull it out and adjust the carb without this tip.
Great video! It was clear and easy to understand. I really enjoyed the way you enlarged the camera shot of the Echo while making youself visible as you explained the fix. Thank you 👍👍
Great idea getting that plug out. I wasted about 15 minutes trying to dig it out with a few sharp pointed picks. Was finally able to but your idea is a much better way of going about it.
I've had my Echo es250 for several years, tried cleaning everything and never helped the top end. I didnt have the right size punch but the flat end of a small drill bit worked fine to get the plug out. Thanks, your hack worked great!
I tried this and it did work. I'm finding I have to keep adjusting almost every time I use the blower. Is that what everyone else is experiencing, too? At one point, I started adjusting the little hidden screw on the top of the carburetor. Do I just tape this flathead to my blower because it's always going to need to be adjusted to work?
HI, I kept this blower for a little while after doing this and I didn't have any problems... Question; does the adjustment screw feel like it's turning really easy? Can you take note of exactly what position you left it in so you can see if it moves a little bit with vibration?
Thanks Rudy! Worked like a charm, my Echo didnt even have the cap over the screw. 1/2 turn left and bam, full power. Appreciate your time to video this fix.
Nice vid. The other critical thing to check on these bogging leaf blowers is the fuel supply line. That line is the one that goes into the tank with the fuel filter attached to its end. if it gets the slightest tear or hole or slit in it, it will suck air and have the same effect as carb needle being too lean. Simplest way to tell if it's a fuel line problem is that the primer bulb keeps running dry.
Oh my gosh, I cannot believe I did not find your video the last time I tried to solve this problem. As you were describing the problem I was like "yes...yes...". Then you said messing with the choke and I was like YES! I was about to give up and trash the blower. Thanks so much for the video.
Thanks we should’ve seen your video before ordered a new carb Put new carbon didn’t make a difference but all carbon did what you said in this video worked amazing thank you. Good job.
I'm glad I found this video. Fortunately it was easy to find. I just bought the ECHO ES 250 today and right out of the box it had this problem. I'll give this a try and see if it clears up that obnoxious bogging.
Have the same blower; yesterday I took the carburetor apart and rebuilt it because I had a fuel leakage problem I couldn't find and decided to replace the seals, needle, spring, etc. Now when I cranked it up it idles good...almost too high though, and when I press the throttle all the way down I get that bogging down problem. Note: I ended up backing a long screw out of the throttle rotor assembly (black box on top) to remove it as part of the carb rebuild; which I didn't need to do (it lifts off without removing it) and can't remember exactly how tight it was turned (looks as it could be some type of carb adjustment?) and I wonder if that may be causing part of the problem. I may try your method and see if it helps, I hope so; a new carb for the blower cost about $78. Insane
HI! Have you checked Amazon for a carb? They are usually in the $15-20 range... An OEM one may be $78, but I'd rather try the after market one first and save a few $$$..
Thanks Rudy- what a great video!! worked like a charm on a Echo PB255 that I trash picked. I turned that set screw counterclockwise about 90-110 degrees and it worked like a charm. But what exactly did that set screw do to the carb? Does anyone know?
Yes, it's a fuel/ air mixture. I'm pretty sure if you backed it out counterclockwise it made the mixture more rich. I think turning it clockwise makes it more lean. I could have that backwards!..
Great video my dear sir! Yea the manufacturers have made it hard by removing high and low fuel adjustment screws or caping them off to tune these little beasts. Epa regs.. thanks epa. They don't want us adjusting these cause we don't have the equipment to tune them in the field. They are afraid of running lean or rich. That is the high screw and opening it gives more air to the diaphragm pumping more fuel. Which it needed
Yes, I think you're exactly right... In my humble opinion the only equipment needed is an ear and a screwdriver..!😂. But yea they've made things harder to fix for sure..
Thanks so much for the video. I plan on doing it today to my church's blower. However, did you put the plug back in and will it get dirty if you leave it out?
Worked like a charm. I used a lighter and an Allen wrench that fit the hole in the plug. My blower works the way it should now. I used to take the filter out to make it to run at full throttle. That blower was a problem from the day I bought it. I usually could run it for one tank of gas but once I refilled it the thing would bog down soon after. So thanks for the fix.
Thanks a lot buddy I’m was about to trash mine was tired of changing parts on it changed out the carb and the coil started up but had no power thanks a bunch
Fantastic video that was very well made and narrated. I have an echo blower that is bogging so I came to TH-cam and found your video explanation on how to fix it. Many thanks to you.
Thank you so much for this video. I installed a new carb on mine and it was doing this. Adjusting the high speed screw like you showed fixed the problem.
I spent another 2 hours today trying to get my Echo pb250ln to run. First I cleaned the exhaust port then cleaned the fuel filter and tried to adjust the carb with a small screwdriver. No joy, I'm stuck with 2/3 throttle as high as it will go. This is the only Echo product I have had problems with.
Yes this particular model wasn't built that great.. At least in my opinion. Most echo products are very good. Could be the carburetor, but no way to know without buying one. Then if it's not, it's wasted money. Could the engine be worn out? Maybe low on the compression? Just throwing it out there...
having the same problem with a backpack echo right now, wondering if there is a similar solution for my model. Im not home so i cant check what model it is, but i will have to check and try this out
This worked - thanks! Any danger in adjusting this screw? I noticed the fan spins at a much faster rate than it ever has... any sweet spot I should look for?
adjusting this screw shouldn't cause it to rev to high. I would get it to the peak and then turn it counterclockwise a little so it's not running to lean.
great tip...i bought one of these for 50$ at a yard sale and i could never get it to run right...new plugs..carb clean and spark arrestor etc....never knew about this...
Great tip! I used it on my PB265-LN and although I had to turn it to the right it worked great. Used a 3/32 Allen and vicegrips to get the plug out. Thanks for sharing and saving me some $$!
@@JLPicard440 I have gone at least twice with the same issue and they gladly keep taking my money. Funny thing is that they have already removed the black security cap on the adjustment screw to simply do what you showed here. Thanks again.
great tip,,but it makes me wonder if you/I put a new carb or the old carb has not been mess with and it was running fine few days back,,,why would this be the fix or need to adjust?
It's possible this can happen even if it was running fine a few days ago. Sometimes atmospheric conditions can be all it takes to mess up the carb settings. If you're in a airplane you often times have to lean or richen the fuel as you go up and down in altitude, I'm not saying that's what's causing it, but it could be as simple as that.
Mine worked great until this very same crap happened and i messed with the choke as well LMAO. I'm 1/3 through the video, in great anticipation of the fix!!!
Great video. The "fix" worked on mine just as you showed, right down to the trick removing the plastic plug. Thanks for the thorough, easy-to-follow instructions.
@@BrianRottermond I'd have to see it, but if you follow your throttle linkage. If you see where the throttle linkage hooks to the carburetor. The part that moves back and fourth should have a screw on one side of it to regulate where it stops at..
@@JLPicard440....Got it. I was adjusting the idle screw, but it was stuck in it "low" position. I got it to move freely and adjusted the idle screw again.....success. Thanks again!
Great tip to fix this. Worked perfectly. Used your hot punch trick to remove the plastic plug and the rest was so easy. Thanks. btw mine was a Echo PB-251
I got the scheppach MFH3300-4P weed trimmer. Worked FINE when I used it in the autumn but has this problem now that you describe. Bogging down when throttled BUT I also have WAY TOO HIGH idle at the same time. As said, worked no prob in the fall and stored indoors at no freeze temp. What excactly does the screw in the primer do?? Al help appreciated!
HI.. the screw adjusts the Fuel / Air mixture. Why does it happen out of the blue? That's a good question that I don't have an answer for. Usually it's set it and forget it, but they do get out of adjustment from time to time. I used to fly RC airplanes and you had to fiddle with those too every so often as many of those use weed-wacker size engines. You should have an idle screw that you can adjust to bring that idle down. You don't want the trimmer line going at high speed when you want to idle the engine.. Possibly if you left fuel in it over the winter that could account for the problem now? I usually like to get ethanol free gas, it seems to keep better than the regular pump stuff.. Lowes usually carries a version of it, but they want like $20 for a gallon can which is nuts.. Some gas stations will actually sell this for much less.. Another idea is a local airport. IF they'll sell you the 100LL fuel that airplanes use, that'd be a great alternative..
Gonna give it a shot, I have a PB 250 and the primer bulb is on the bottom of carb, not the side like yours so I will take it off and give the screw a turn and put it back on and see what happens.
@@JLPicard440 upon closer inspection, mine has a high and low adjustment on the side so I ordered a carb adjustment kit as it requires a special tool to adjust it. Hopefully it is just a simple adjustment that is required to fix it. I have had that thing off there 3 times and cleaned it.
@@JLPicard440 got my adjusting tools yesterday and it made it a ton better, just got my needle adjusting gauges for the walbro carb today, so it looks like it will come off one more time to make sure the needle height is correct. I’m learning as I go! LOL
@@JLPicard440 thank you for the quick reply let me ask you a question I have a red max blower EB4400 that I have change the coil, carb, and it has 150 of compression but will not start any idea what I can do next I want to try and make the repair myself and not take it to a repair shop any help would be great.
@@henrydixon3159 Thats a good one.. sounds like you've done everything I would have tried. Does starting fluid have any reaction? Or if you don't have any, you can drip a couple drops of gasoline in there... and see if there's any action..
Did not fix mine but was really hopeful that it would. Also if it did then it would not stay because it is so loose. I was expecting it to thread in and out like the old types but it appears to just rotate. I'm now at a loss here. Checked muffler inlet, outlet and spark arrester screen. They looked really clean. I disassembled the carb, sprayed carb cleaner in there and blew it all out with compressed air. It actually looked pretty clean in there too. Mine will not idle but it does run at full throttle but only maybe 1/2 or 2/3 of full RPM. I forgot to check the spark plug gap but it looked good at quick glance. I'll replace it with a new one because they are only $4 and yes I will check the gap before installing. One thing I did try was to run it at full throttle with the air filter off and mist it with carb cleaner. It did not seem to make any difference so either it is not fuel related or I need a stronger liquid like starting fluid or mist some fuel mixture in there. One thing that makes me lean towards it being a fuel issue is that it doesn't seem like any smoke is coming out of the exhaust and I know the oil/fuel ratio is good. The fuel is 90 octane ethanol free gas is less than a month old. My Echo trimmer runs great on it and it does smoke a little but not like it used to. Maybe whatever oil I'm using now doesn't smoke as much as the other oils?
Wow... sounds like you've tried everything I would have tried... How about the fuel line? Sometimes they can get a little hole in them and cause the engine to pull air in with the fuel and cause problems...
I replaced the spark plug with a new one. It was only .024" gap when it should have been .027" so I adjusted it. The old one has the correct gap. No change in performance. I removed the in tank filter to see if it ran any better and it didn't help either. Then I ran it again without the air cleaner and sightly misted it with starting fluid and if I sprayed just right the RPMs went up a fair amount. Because of that result I went ahead and ordered a new OEM carb and fuel line/filter kit. Fingers crossed.
Oh wow... I hope the new carb solves the issue. Did you inspect the fuel line real close when you had the filter out? I've seen holes really small where if you stretch the fuel line a little bit, then you can see the hole..
@@JLPicard440 I put the new carb on and still the same issue. Using a bright light and looking through a magnifier I looked (and stretched a little) at the fuel lines and I don't see any holes. The new fuel line kit is not here yet but I'll put it on anyway when it gets here. Now what do I check next? Could it be a weak coil or the flywheel key is sheared and throwing it out of time? I still think it acts like it is fuel related.
My PB 25cc backpack Blower I got for my grandson bogged immediately. It had 2 restrictor plates above the spark arrestor. 1st plate cut the exhaust port in half.2nd cut it in half again. I removed the second and the machine woke up. After some more research I hope to find I can remove the first and let it breath. The second is for noise restrictions and emissions for the left coast princess state. Exhaust restriction will foul a carbs delivery. Without allowing the exhaust to breath for any period will cause fouling. A quick remedy to increase RPM is to lean the engine to compensate for exhaust and intake fouling. Do the exhaust first and early. Then you should never have to lean the fuel air mixture.
Yes leaning it could cause it to run hot. Not sure if those restrictor plates are a necessity. Race cars run with open headers so there's virtually no restriction, but sometimes a 2 cycle needs some back pressure to pressurize the fuel tank... so I can't be sure that you can remove both of those and get away with it. You could try it and see how it runs.. or a search of threads from google might reveal if you can remove both of them.
@@JLPicard440 I only use it to blow off my driveway so it may sit two weeks at a time between cranks. I did check the spark arrestor screen and carb port for buildup. That looked very clean. The blower is only a couple years old. I use the Stihl 2.6 oz., 50:1 2 cycle oil. So that should be ok. I use staybill in my 5 gallon big can and go to a 1 gal. can from it.
@@dougjohn45 Yea fuel wise you sound like you're taking care of things... I was going to suggest the spark arrestor in the muffler... Could be the carburetor, but hate to spend money since I'm just guessing.. Does the compression feel normal?
@@JLPicard440 Yep Rudy, the compression appears to be normal and good. I'll tinker with it some today. With no more run time that it has, It's hard to believe something is worn out. Just an adjustment somewhere. With the symptoms it has, I can't believe it's not the adjustment screw just like yours. I'll try fresh gas just to eliminate that. It's possible the gas could be contaminated from the gas station.
I have an Echo 225 trimmer same thing you can also remove that brass plug because it is a limiter also by doing that you can remove the mixture screw also I run Sthil HP oil the stuff in the silver bottle it leaves no carbon deposits and you never have that black oily snot dripping from the muffler starts better and better throttle response
So I've changed the spark arrestor (needed it) and tried this. After changing the arrestor, my blower worked fine for about 30 minutes and then started dying again. I've tried adjusting the screw. The blower will start fine and run when on a flat surface but whenever I pick it up and move around it stalls out. I'm at my wits end. Any suggestions?
I do not routinely comment on TH-cam videos, but I am compelled to comment there to THANK YOU for finally solving what has been driving me absolutely crazy for the last 3 weeks.

I see that your video was posted up 5 years ago. Today, it really did help me. My echo had been doing the same thing and that's because I had just picked it up from a repair shop.

Thank you for the great tip/procedure! Also, for anyone who does not have the right tools: I didn't have the right size punch but a 5/64" allen wrench heated with a cig lighter worked well.
Absolutely! Anything in that size range would work. Thanks for the great feedback.. 🙂
Same for me... Great tip. Glad to have found this. Thx!
Thanks for the allen wrench tip. Worked like a champ.
That was one of the best you tube videos I have seen in a long time even though I don’t have that particular issue. The videography especially the close ups were on point, and the audio was clear. Subscribed. Thanks.
Great to hear! Thank you so much! You're welcome..
Brilliant! Followed your instructions and it worked wonderfully. I ended up clamping an allen wrench to a vise grip, heated up the wrench, stuck it down into the opening, waited a couple of minutes and popped that baby right out. Thanks so much for the great words of wisdom.
Excellent! I'm glad you got it going😊
Dude that allen wrench idea was genius. Glad i read this comment after the video. Got my power back in my blower!
Thank you! Got an Echo blower at a garage sale for $20. Adjusted the screw and it's back to full power! Unreal!!!
Awesome! So glad I could help..
Great find! Echo OPE lasts forever

I was about to order a new carburetor. I bought the same leaf blower off of my neighbor for $20 dollars yesterday but it was doing the same thing. I adjusted the mix screw and it worked perfectly! Just had to turn it counter clockwise about 1 turn and a half. The little Plastic cover part of the screw was aggravating to get out so I just drilled it. Thank you so much!
So awesome my video was able to help you... Hopefully your neighbor won't be to angry when they discover it was an easy and even worse a free fix!😂
OMG! I have been through 2 carburetors trying to figure out this problem and you did it with about 2 turns of a screw...awesome!
Excellent..! Glad I could help. 😀
BRILLIANT. We have two of these in the family and both run too lean. They always start right up fine when it’s cold. BUTTT😡 then I have to play 1/4 choke games for 20 seconds to keep it running or it dies. Then it will finally run full throttle . Trouble is both of them are obviously not running anywhere near what should be full throttle ever. I can’t wait to give this a try. Thanks a million!!
Excellent! I'll keep my fingers crossed for ya... :-)
Thanks a million! My pb255 hasn’t run in a year.
I’d replaced all seals, gaskets, bulb, lines, filters, spark plug and it wouldnt fill the primer bulb in 2019 but after all that it still wouldn’t run.
Out of utter necessity I decided to give it another try again today.
The primer bulb wouldn’t fill so the blower would only run for a short spurt and then shut off. I had the fuel lines to the carb backwards!Fixed that, it would run but would bog under load like your video shows.
Thank goodness I found your video!
I used the torch method to remove the black plug as you showed. Used the end of a small broken piece of a needle file I had laying around. I leaned out the mixture screw by turning counter clockwise just until it would run smooth at high rpm, not bog, had good transient throttle response and didnt smell dry, run too hot or sound like it was running lean.
Kudos to you! This video got my tool up and running again. Many thanks. 🙏
So awesome! You're welcome and thanks for sharing..😊
I just completed this procedure and it worked exactly as advertised. Used a nail with a vice grip and a bbq lighter. Thank You! Subscribed👍
Excellent! Yes anything like that will work... :-)
Good concise video. I knew there had to be a screw for adjustment somewhere but could not locate it. Thanks for the insight. Echo PB 251
You're welcome! So glad I could help. 😊
If you don’t have a punch, the back end of a 3/32” drill bit works really well. Thank you for the video!
Excellent! Yes anything of that size will work great..
this technique worked perfectly. My 13 year old son and I worked on ours… used a grill lighter and did not need a blow torch. Used a small Allen wrench. Amazing!
Excellent! Glad you got it going again.. 😊😊
My leaf blower has been bogging like this nearly since the day I bought it and got it out of the box. Thank you for making this video. By the way, a hook pick will pull that plug out too.
You're welcome! So glad I could help... 😊. Thanks for the tip..
My father gave me this leaf blower right after he bought it because he didn’t like how it ran and I told him the carburetor just needed tweaking. I knew where the screw was but I was wondering why did they put a plug there. I think I can use an easy out to get it out. Nice video. 👍🏻
yea a easy out would probably work. I think they put the plug there for emmisions reasons... but then when there's a problem like this, they don't want you to adjust it. This fix won't fix it every time.. but it will a lot of the times...
Take a Bath Productions - yeah I’m just curious if this may have been set up at a different altitude and living up here in the north eastern part of America throws it off a good bit.
@@fattony123082 It's possible, but I kinda doubt it. I've seen more than one with this problem. I'm here in Va.. 300 ft MSL
It's for emissions and for the idiots who adjust it improperly and destroy the engine (that way they have more evidence of improper modification in case of a warranty claim).
I wanted to use my echo to blow snow off my sidewalk but it didn’t have enough power to move it. I watch your video and it fixed my low power. I didn’t have a 3/32, punch so I ground the tip off a nail and used it with a pair of vise grips, worked flawlessly! Great Video
Excellent idea! that would certainly work just fine. Glad you got it going... 😀
Thanks for the video! My blower would start, but then bogged down and cut off. After I drilled out the black plastic nub, I turned the screw counterclockwise 1/2 to 1 revolution, and then it didn't choke down any more. Saved me from having to buy another blower. Thanks again.
Excellent! That's nice to hear.. :-)
Good idea on drilling out that little plug.
@@tommysmalls8634 Sorry for the late response, your comment didn't come until today.. Yes, thank you!
Thank you thank you thank you! I was getting half power and thought it just needed to warm up... Nope adjustment solved my issues. I was getting half power and now she BLOWS!! Allen wrench instead of a punch worked great as well to remove the plug!! Sir i really cant thank you enough on this one!
You're welcome! I'm so glad you got it working again... 🙂
Terrific video. 5 minute fix and saved a big repair bill. Easy. Didn't have a torch but gas stovetop range worked fine.
Thanks for the great feedback! Glad you were able to get your blower going again... 😊
I LOVE YOU MAN! THat worked perfectly. The only hard part eas digging out that plug. I didn’t want to sacrifice a craftsmannpunch’s temper. I got it out with a 1” drywall screw in about 3 minutes.
Yes! Good idea.... Sorry for the late response, your comment was lost in the mix...
I did everything just like you said and blower is running perfect now thank you for sharing this information.
Great job!
You sir are a genius and a hero. So glad I found this before buying a new carb. Worked in less than 5 mins
Great to hear!
Had same problem after installing a new carb, fuel lines, s plug, air filter...
Watched this video and luckily my new carb didn't have that plug to remove. Just gave it throttle and turned it counterclockwise and is ALOT better.
This video helped no doubt.
That's awesome! Also one thing I forgot to mention was sometimes the spark arrestor in the muffler can get clogged, so that's something to consider.
Worked perfectly. I can now resume being the mad blower!
I found a coarse screw turned into plastic cap worked as a puller, no problem.
I think the screw vibrates out of tune with use as I needed to re-adjust every few blows.
Yes that'll work great.. and you could be right about the vibration.. You could take that screw completely out and put a drop of lock tight on the threads, screw it back in and adjust it properly, then it should stay.. But then you'll have a hard time adjusting it again if atmospheric changes causes it to need adjusted again, so I don't really recommend it, but it's an idea.
I had this same problem on my PB250 but this " fix " was not the issue . My exhaust port was almost blocked by carbon. I cleaned this port and the PB250 is brand new again. Just like it says in the Owners manual. I have been told it is due to cheap oil and gas .Thanks
Excellent. Yes I am aware of the spark arrestor in the muffler causing issues sometimes. I wish I would have mentioned that in the video as a possible culprit..
GREAT JOB!
Same thing happened to me. Son tried to start the blower without the switch tuned to "ON" position so when I started the blower it almost sounded like a fouled plug. Replaced plug and same thing. Almost went to the Depot and picked up a new one but decided to google the problem and low and behold, I found you. The tip about putting a heated punch in the plastic plug is AWESOME. I don't think I would have been able to pull it out and adjust the carb without this tip.
Awesome..! I'm glad you were able to get it going... :-)
Great Video my friend. You just saved me $149 + tax from Home Center. My two years old blower was acting up and I was able to tune up.Thanks
Glad I could help... :-)
Great video! It was clear and easy to understand. I really enjoyed the way you enlarged the camera shot of the Echo while making youself visible as you explained the fix. Thank you
👍👍
Excellent! Thanks for the great comment... :-). I'm glad you liked the format too... :-)
Great idea getting that plug out. I wasted about 15 minutes trying to dig it out with a few sharp pointed picks. Was finally able to but your idea is a much better way of going about it.
Excellent! Glad you got it going.. 😊
I've had my Echo es250 for several years, tried cleaning everything and never helped the top end. I didnt have the right size punch but the flat end of a small drill bit worked fine to get the plug out. Thanks, your hack worked great!
So excellent! 😎
I tried this and it did work. I'm finding I have to keep adjusting almost every time I use the blower. Is that what everyone else is experiencing, too? At one point, I started adjusting the little hidden screw on the top of the carburetor. Do I just tape this flathead to my blower because it's always going to need to be adjusted to work?
HI, I kept this blower for a little while after doing this and I didn't have any problems... Question; does the adjustment screw feel like it's turning really easy? Can you take note of exactly what position you left it in so you can see if it moves a little bit with vibration?
One of the best DIY videos I’ve seen. Well done.
Excellent! Thanks for the great comment...:-)
Great job, camera work & clear voice. As soon as its daylight I am going to try this. 'So do I put the rubber piece back in afterwards???
Thank you! You can, but I never did put it back..
Thanks Rudy! Worked like a charm, my Echo didnt even have the cap over the screw. 1/2 turn left and bam, full power. Appreciate your time to video this fix.
Awesome! Glad you got it going again.... 🙂
I did it exactly as you instructed. Works perfectly now. Thanks man!
Great to hear!😊😊
That is an awesome tip on removing the plug to access adjustment screw. Most have you take everything apart. This is a better way. Thanks
Awesome! You're welcome.. Thanks Yogi.. 🙂
Nice vid. The other critical thing to check on these bogging leaf blowers is the fuel supply line. That line is the one that goes into the tank with the fuel filter attached to its end. if it gets the slightest tear or hole or slit in it, it will suck air and have the same effect as carb needle being too lean. Simplest way to tell if it's a fuel line problem is that the primer bulb keeps running dry.
absolutely right! Thanks for the input... 😀
My pleasure Sir.@@JLPicard440
Oh my gosh, I cannot believe I did not find your video the last time I tried to solve this problem. As you were describing the problem I was like "yes...yes...". Then you said messing with the choke and I was like YES! I was about to give up and trash the blower. Thanks so much for the video.
You're welcome! Thank you for the great feedback 🙂
Nice video! Simple, clear and to the point. Keep up the good work.
Thank you! Thanks for the great feedback.. 🙂
This was a great video and after months of searching and replacing carb, this was the ticket!
That's awesome! Glad I could help.. 😀
Thanks we should’ve seen your video before ordered a new carb Put new carbon didn’t make a difference but all carbon did what you said in this video worked amazing thank you. Good job.
Excellent! Glad you got it going again... 😀
WOW followed directions- worked like a charm!!!!
Less than 5 minutes 👍
Awesome!... :-)
I'm glad I found this video. Fortunately it was easy to find. I just bought the ECHO ES 250 today and right out of the box it had this problem. I'll give this a try and see if it clears up that obnoxious bogging.
If it were me, if you haven't already removed the plastic plug... I'd take that puppy right back if you just bought it!
Have the same blower; yesterday I took the carburetor apart and rebuilt it because I had a fuel leakage problem I couldn't find and decided to replace the seals, needle, spring, etc. Now when I cranked it up it idles good...almost too high though, and when I press the throttle all the way down I get that bogging down problem. Note: I ended up backing a long screw out of the throttle rotor assembly (black box on top) to remove it as part of the carb rebuild; which I didn't need to do (it lifts off without removing it) and can't remember exactly how tight it was turned (looks as it could be some type of carb adjustment?) and I wonder if that may be causing part of the problem. I may try your method and see if it helps, I hope so; a new carb for the blower cost about $78. Insane
HI! Have you checked Amazon for a carb? They are usually in the $15-20 range... An OEM one may be $78, but I'd rather try the after market one first and save a few $$$..
I love you. This was perfect.
Carb clean still didn't work. This was it.
That grommet is tricky though.
Awesome! Glad you got it going...
Thanks Rudy- what a great video!! worked like a charm on a Echo PB255 that I trash picked. I turned that set screw counterclockwise about 90-110 degrees and it worked like a charm. But what exactly did that set screw do to the carb? Does anyone know?
Yes, it's a fuel/ air mixture. I'm pretty sure if you backed it out counterclockwise it made the mixture more rich. I think turning it clockwise makes it more lean. I could have that backwards!..
Great video my dear sir! Yea the manufacturers have made it hard by removing high and low fuel adjustment screws or caping them off to tune these little beasts. Epa regs.. thanks epa. They don't want us adjusting these cause we don't have the equipment to tune them in the field. They are afraid of running lean or rich.
That is the high screw and opening it gives more air to the diaphragm pumping more fuel. Which it needed
Yes, I think you're exactly right... In my humble opinion the only equipment needed is an ear and a screwdriver..!😂. But yea they've made things harder to fix for sure..
Wish I knew about this fix last year, replaced carb and only worked for one season. Thanks for posting this well made video, it really helped.
Excellent! Thanks for the comment.. :-)
Thanks so much for the video. I plan on doing it today to my church's blower. However, did you put the plug back in and will it get dirty if you leave it out?
HI, I didn't put the plug back.... Never had any trouble afterwards.
Thank you! I was able to remove the brass and plastic plug. Adjusted the carb and now is like brand new. More power and no bogging at full throttle.
Excellent! You're welcome..
Worked like a charm. I used a lighter and an Allen wrench that fit the hole in the plug. My blower works the way it should now. I used to take the filter out to make it to run at full throttle. That blower was a problem from the day I bought it. I usually could run it for one tank of gas but once I refilled it the thing would bog down soon after. So thanks for the fix.
Excellent! Thanks for the comment!
Fixed my bogging issue today. Saved me quite a bit of time. Thank you!
Excellent.... So glad I could help. You're welcome!
Thanks a lot buddy I’m was about to trash mine was tired of changing parts on it changed out the carb and the coil started up but had no power thanks a bunch
Great!
Fantastic video that was very well made and narrated. I have an echo blower that is bogging so I came to TH-cam and found your video explanation on how to fix it. Many thanks to you.
Awesome, thank you!
Thanks for the video man, used your advice on my Pb 265l and it runs like a scalded dog now! Have a good one!
You're welcome... Thanks for the great comment... :-)
Excellent video. I was about to bring my blower to the shop. Good thing I saw this clip. I tried what you said to do and it worked like a charm.
That's awesome! Glad it helped😊
This works great. But a used a tiny drill bit to grab the plug. Thanks Rudy.
Glad I could help... Yes absolutely, anything small will work great!
I did everything you said with great detail. It worked perfectly. great help. Thanks
That's excellent... You're welcome! 😀
I had a tough time getting the plug out but worked out in the end. Thanks...
You're welcome!
Thank you so much for this video. I installed a new carb on mine and it was doing this. Adjusting the high speed screw like you showed fixed the problem.
Excellent! You're welcome and I'm glad the video was helpful.. 😀
I spent another 2 hours today trying to get my Echo pb250ln to run. First I cleaned the exhaust port then cleaned the fuel filter and tried to adjust the carb with a small screwdriver. No joy, I'm stuck with 2/3 throttle as high as it will go. This is the only Echo product I have had problems with.
Yes this particular model wasn't built that great.. At least in my opinion. Most echo products are very good. Could be the carburetor, but no way to know without buying one. Then if it's not, it's wasted money. Could the engine be worn out? Maybe low on the compression? Just throwing it out there...
having the same problem with a backpack echo right now, wondering if there is a similar solution for my model. Im not home so i cant check what model it is, but i will have to check and try this out
Yes, it's worth looking at..
I used a nail instead of a punch and my stove instead of a blow torch. NOTE: dont touch hot nails lol. Use a pair of pliers. Works the same
Great tip! Yes that would work.... :-)
This worked - thanks! Any danger in adjusting this screw? I noticed the fan spins at a much faster rate than it ever has... any sweet spot I should look for?
adjusting this screw shouldn't cause it to rev to high. I would get it to the peak and then turn it counterclockwise a little so it's not running to lean.
Worked! I used the head of a small nail held with some pliers.
Excellent!
Thank you for the video. I pulled out the rubber cap and adjusted the carb. Works great now. You da man.
Awesome! You're welcome... :-)
great tip...i bought one of these for 50$ at a yard sale and i could never get it to run right...new plugs..carb clean and spark arrestor etc....never knew about this...
Glad I could help... Did this fix work for you?
Worked like a charm!!!
Does anyone know why this screw comes out of adjustment to begin with??
Could be vibration over time, or maybe just atmospheric conditions changing...
Great tip! I used it on my PB265-LN and although I had to turn it to the right it worked great. Used a 3/32 Allen and vicegrips to get the plug out. Thanks for sharing and saving me some $$!
Awesome! You're welcome.. 🙂
Thanks SO much!!! This worked perfectly! Saved me a major hassle!
You're welcome!... Glad it helped.
Thank you this saved me buying a new blower!
You are welcome!
You just saved me a trip to the repair shop!
That's great! Glad it helped... :-)
@@JLPicard440 I have gone at least twice with the same issue and they gladly keep taking my money. Funny thing is that they have already removed the black security cap on the adjustment screw to simply do what you showed here.
Thanks again.
great tip,,but it makes me wonder if you/I put a new carb or the old carb has not been mess with and it was running fine few days back,,,why would this be the fix or need to adjust?
It's possible this can happen even if it was running fine a few days ago. Sometimes atmospheric conditions can be all it takes to mess up the carb settings. If you're in a airplane you often times have to lean or richen the fuel as you go up and down in altitude, I'm not saying that's what's causing it, but it could be as simple as that.
Mine worked great until this very same crap happened and i messed with the choke as well LMAO.
I'm 1/3 through the video, in great anticipation of the fix!!!
I hope it works for ya!
Thanks for the video brother. Will try it this morning. Oh, are you able to put rubber cap back in or need to replace with new one?
I personally just left it out. You can try to put it back if you want to, but I'm not sure it'll stay.
@@JLPicard440 once I did it I understood it was merely a cover to keep the average Joe out. Thanks again
Toss it ! It has no purpose to begin with that you would care about.
Thanx brutha worked perfectly. Was literally on my way to buy a new one ..until I saw this 💪
That's excellent! SO glad I was able to help... 😀
Great video. The "fix" worked on mine just as you showed, right down to the trick removing the plastic plug. Thanks for the thorough, easy-to-follow instructions.
Excellent! You're welcome... :-)
Thanks, this was really helpful. Full power, but I can't get it to just idle. Any suggestions on idling?
You're welcome.. The idle screw isn't set to low is it?
@@JLPicard440, not sure. Where do I find the idle screw?
@@BrianRottermond I'd have to see it, but if you follow your throttle linkage. If you see where the throttle linkage hooks to the carburetor. The part that moves back and fourth should have a screw on one side of it to regulate where it stops at..
@@JLPicard440....Got it. I was adjusting the idle screw, but it was stuck in it "low" position. I got it to move freely and adjusted the idle screw again.....success. Thanks again!
@@BrianRottermond That's awesome! You're welcome.. 🙂
Sorry, forgot to ask WHY is this problem arising out of the blue? The brass screw issue... Is it built to fail?? Will try it out. Thanks
HI, please see my other response..
Great tip to fix this. Worked perfectly. Used your hot punch trick to remove the plastic plug and the rest was so easy. Thanks. btw mine was a Echo PB-251
Glad it helped, You're welcome 😊😊
Wow! I found a blower on the side of the road and did this and cleaned the rusty carb and it runs like a gem
Nice work! I love those trash finds!... :-)
What does the screw do? I'm just curious if it changes the gas mix or what. Does it make the blower any louder?
HI. Yes it changes the fuel mixture. No it doesn't make the blower any louder.. Thanks for the comment..🙂
I got the scheppach MFH3300-4P weed trimmer. Worked FINE when I used it in the autumn but has this problem now that you describe. Bogging down when throttled BUT I also have WAY TOO HIGH idle at the same time. As said, worked no prob in the fall and stored indoors at no freeze temp. What excactly does the screw in the primer do?? Al help appreciated!
HI.. the screw adjusts the Fuel / Air mixture. Why does it happen out of the blue? That's a good question that I don't have an answer for. Usually it's set it and forget it, but they do get out of adjustment from time to time. I used to fly RC airplanes and you had to fiddle with those too every so often as many of those use weed-wacker size engines. You should have an idle screw that you can adjust to bring that idle down. You don't want the trimmer line going at high speed when you want to idle the engine.. Possibly if you left fuel in it over the winter that could account for the problem now? I usually like to get ethanol free gas, it seems to keep better than the regular pump stuff.. Lowes usually carries a version of it, but they want like $20 for a gallon can which is nuts.. Some gas stations will actually sell this for much less.. Another idea is a local airport. IF they'll sell you the 100LL fuel that airplanes use, that'd be a great alternative..
Gonna give it a shot, I have a PB 250 and the primer bulb is on the bottom of carb, not the side like yours so I will take it off and give the screw a turn and put it back on and see what happens.
I hope it fixes it for you!... 😊
@@JLPicard440 upon closer inspection, mine has a high and low adjustment on the side so I ordered a carb adjustment kit as it requires a special tool to adjust it. Hopefully it is just a simple adjustment that is required to fix it. I have had that thing off there 3 times and cleaned it.
OH yea.... got the T-Shirt... 😂...
@@JLPicard440 got my adjusting tools yesterday and it made it a ton better, just got my needle adjusting gauges for the walbro carb today, so it looks like it will come off one more time to make sure the needle height is correct. I’m learning as I go! LOL
Excellent! I do that all the time. Learning is a lifelong process...
Great video my Echo trimmer is doing just that I don't have small punch can I use a screwdriver?
Yes anything that'll fit in there to remove the plastic plug. A nail should even work..
@@JLPicard440 thank you for the quick reply let me ask you a question I have a red max blower EB4400 that I have change the coil, carb, and it has 150 of compression but will not start any idea what I can do next I want to try and make the repair myself and not take it to a repair shop any help would be great.
@@henrydixon3159 Thats a good one.. sounds like you've done everything I would have tried. Does starting fluid have any reaction? Or if you don't have any, you can drip a couple drops of gasoline in there... and see if there's any action..
@@JLPicard440 thanks I will give that go and see
I love your FIX Idea and love the video pip setup great job! Thanks
Thanks so much!
Did not fix mine but was really hopeful that it would. Also if it did then it would not stay because it is so loose. I was expecting it to thread in and out like the old types but it appears to just rotate. I'm now at a loss here. Checked muffler inlet, outlet and spark arrester screen. They looked really clean. I disassembled the carb, sprayed carb cleaner in there and blew it all out with compressed air. It actually looked pretty clean in there too. Mine will not idle but it does run at full throttle but only maybe 1/2 or 2/3 of full RPM. I forgot to check the spark plug gap but it looked good at quick glance. I'll replace it with a new one because they are only $4 and yes I will check the gap before installing. One thing I did try was to run it at full throttle with the air filter off and mist it with carb cleaner. It did not seem to make any difference so either it is not fuel related or I need a stronger liquid like starting fluid or mist some fuel mixture in there. One thing that makes me lean towards it being a fuel issue is that it doesn't seem like any smoke is coming out of the exhaust and I know the oil/fuel ratio is good. The fuel is 90 octane ethanol free gas is less than a month old. My Echo trimmer runs great on it and it does smoke a little but not like it used to. Maybe whatever oil I'm using now doesn't smoke as much as the other oils?
Wow... sounds like you've tried everything I would have tried... How about the fuel line? Sometimes they can get a little hole in them and cause the engine to pull air in with the fuel and cause problems...
I replaced the spark plug with a new one. It was only .024" gap when it should have been .027" so I adjusted it. The old one has the correct gap. No change in performance. I removed the in tank filter to see if it ran any better and it didn't help either. Then I ran it again without the air cleaner and sightly misted it with starting fluid and if I sprayed just right the RPMs went up a fair amount. Because of that result I went ahead and ordered a new OEM carb and fuel line/filter kit. Fingers crossed.
Oh wow... I hope the new carb solves the issue. Did you inspect the fuel line real close when you had the filter out? I've seen holes really small where if you stretch the fuel line a little bit, then you can see the hole..
@@JLPicard440 I did not try that but out of curiosity will do that when I change the lines.
@@JLPicard440 I put the new carb on and still the same issue. Using a bright light and looking through a magnifier I looked (and stretched a little) at the fuel lines and I don't see any holes. The new fuel line kit is not here yet but I'll put it on anyway when it gets here. Now what do I check next? Could it be a weak coil or the flywheel key is sheared and throwing it out of time? I still think it acts like it is fuel related.
My PB 25cc backpack Blower I got for my grandson bogged immediately. It had 2 restrictor plates above the spark arrestor. 1st plate cut the exhaust port in half.2nd cut it in half again. I removed the second and the machine woke up. After some more research I hope to find I can remove the first and let it breath. The second is for noise restrictions and emissions for the left coast princess state. Exhaust restriction will foul a carbs delivery. Without allowing the exhaust to breath for any period will cause fouling. A quick remedy to increase RPM is to lean the engine to compensate for exhaust and intake fouling. Do the exhaust first and early. Then you should never have to lean the fuel air mixture.
Yes leaning it could cause it to run hot. Not sure if those restrictor plates are a necessity. Race cars run with open headers so there's virtually no restriction, but sometimes a 2 cycle needs some back pressure to pressurize the fuel tank... so I can't be sure that you can remove both of those and get away with it. You could try it and see how it runs.. or a search of threads from google might reveal if you can remove both of them.
This is exactly what my 255ln blower is doing however the hidden adjustment screw didn't work on mine Any othersuggestions ? Thanks. Doug in Evans Ga.
Oh no! Has it been sitting for a while?
@@JLPicard440 I only use it to blow off my driveway so it may sit two weeks at a time between cranks. I did check the spark arrestor screen and carb port for buildup. That looked very clean. The blower is only a couple years old. I use the Stihl 2.6 oz., 50:1 2 cycle oil. So that should be ok. I use staybill in my 5 gallon big can and go to a 1 gal. can from it.
@@dougjohn45 Yea fuel wise you sound like you're taking care of things... I was going to suggest the spark arrestor in the muffler... Could be the carburetor, but hate to spend money since I'm just guessing.. Does the compression feel normal?
@@JLPicard440 Yep Rudy, the compression appears to be normal and good. I'll tinker with it some today. With no more run time that it has, It's hard to believe something is worn out. Just an adjustment somewhere. With the symptoms it has, I can't believe it's not the adjustment screw just like yours. I'll try fresh gas just to eliminate that. It's possible the gas could be contaminated from the gas station.
@@dougjohn45 Arrrgh.... I wish I could have had a more definitive answer... :-(
Rudy do we put the little piece back in or leave it out?
I would leave it out.. If you can put it back it might keep dust and stuff from getting in there, but I doubt if it really matters..
@@JLPicard440 thank you sir
Rudy I have the older one you mentioned with the high and low slots. How do I adjust one of those? Do you have a video with instructions on how to?
Thanks Rudi, this worked like magic!
Awesome! Glad I could help.. 😀. You're welcome...
I have an Echo 225 trimmer same thing you can also remove that brass plug because it is a limiter also by doing that you can remove the mixture screw also I run Sthil HP oil the stuff in the silver bottle it leaves no carbon deposits and you never have that black oily snot dripping from the muffler starts better and better throttle response
Oh good to know. I was just at local Stihl dealer yesterday and got a silver bottle of oil. Sounds like it's the way to go... thanks for the tip!
I subscribed as soon as I saw the intro
Awesome! Thank you.. 🙂
So I've changed the spark arrestor (needed it) and tried this. After changing the arrestor, my blower worked fine for about 30 minutes and then started dying again. I've tried adjusting the screw. The blower will start fine and run when on a flat surface but whenever I pick it up and move around it stalls out. I'm at my wits end. Any suggestions?
Have you checked the fuel lines?
@@JLPicard440 Thanks for the response. I actually just replaced the fuel line about a month ago as one was split and not connecting.
