I took the same saw to a repair shop a few years ago and they told me that I needed a new carb, $85 bucks later I was good for a while. But I didn't realize that the alcohol in gas will turn to varnish if you don't use it up. I am determined to fix this problem this time, as I also did with my lawn mower twice. Now I buy gas with no alcohol in it. Excellent video, Thanks
Thank you, thank you, thank you. I followed your step-by-step video and solved why my Echo chainsaw wouldn't start. It's now running flawlessly. You, literally, saved me from spending hundreds on a new machine. Your are awesome, my friend!!! Information is POWER!!!
@@newt66c33from what I see on other repair videos you specifically don't want it to be clicking in and out. That means it is stiff and needs replaced.
@@newt66c33100% wrong! If it clicks, it’s past toast. Bin it. They should be very soft and supple. As soon as they start to stiffen; they should be replaced.
Wow straight forward instructions. You gave me the confidence to open mine up and get it running I have never committed myself to fix a small engine before. Respectfully Sack
It took a bit of searching to find a video that took me where I was trying to get to. Thanks for the help. Speaking from experience, be careful about soaking up too much carb and brake cleaner through your hands.
My fairly new Echo CS 490 wouldn't start, or even fire when I shot ether into the carb. I'd about given up when my wife found this video. (I had watched several others, to no avail). I cleaned the carb., and now it starts and runs like a champ. THANK YOU for posting this!
Dump old gas and replace with fresh. Add a little Seafoam engine treatment to the fresh gas+oil, cycle primer bulb 5 times, pull cord 5 times with choke on, then let sit for 24 hrs and soak. Next day try to start again. Fixes itself 8/10 times in my experience if the diaphragm and fuel lines are good with no saw breakdown.
What a delight to see a smoothly explained theory, tear-down, diagnosis, and rebuild. This is an excellent video beyond just showing how to repair because the instructor is clear to describe what he's doing along with suggestions. Thanks
When you're done playing, replace the diaphragm. It's ALWAYS the diaphragm. Change the diaphragm once a year regardless If you use the saw or not. The part cost less than $1.
Great video, I watched your carb cleaning portion and cleaned my carb, put back together, also cleaned my spark plug, adjusted the spark plug screws and running like a champ again, hadn’t used it in about two years, cut down a tree that was next to the house after finished it
Way to go... and if you don't use it much be sure to drain fuel out of gas tank and run it out of Carb and she should start right up when you are needing to use it. Also doesn't hurt to pour a little 2 cycle oil in the fuel tank and pull the start cord to get a little in the carb to keep it nice while in storage.
My Husqvarna 240 lost spark so I replaced the coil and plug. It still didn't start and started dumping fuel out the exhaust. I installed a new carb, filter and lines and set the H & L screws out 1 1/2 turns. Now I have fuel and spark and it still won't start.
Thanks for the great instructions, the secret is to check same for same diaphragms, some aftermarket ones look the same but some dont have the small holes. Yes I found out the hard way
This video helped me. My chainsaw is the same kind as the one you was working on. Thank you so much. Now my chainsaw is working. More ppl should put videos on every chainsaw to help the ppl that dont have the money to take it to a chainsaw store to have it repaired.
That right there was my Stihl HS45. I have one that works like a charm, then a newer one that wouldn’t start no matter what I replaced. I succumbed and brought it to a small-engine repair place. He said it was a malformation in one of my gaskets. I’ll let you know if that truly solves the issue. This video is very helpful for process in the event I may need it. Thank you.
"Helping you online" helped me on line so now I can try something off line. I have exactly the same issue with a Ryobi. If I get it going I'll shout back. Ta ever so!
Thanks for the best most informative video. My 236 runs but won't keep running. The fuel is old but ethanol free. I think the 2stroke that was pre mixed with the petrol has gummed up the carb. I liked the way you didn't skip bits like the throttle rod not being connected. Its an easy mistake that a layman might miss. Thank you
Great video. It revealed many mysteries. It also confirmed my thankfully infrequent response to starting troubles ... take the bloody thing to a good small engine mechanic and let them sort it out. That might have taken you about 30 minutes. It would have taken me a couple of hours and I doubt that I could have put the thing back together again even if I figured out how to take it apart. Cheers mate.
Note i did not finish watching the video. To see what the carbs problem was. But thought id mention a trick everyone can try as soon as one doesn't want to stay running or even doesn't run top notch. My husky did it yesterday. First start of the season was a no go. Readjust and i was off and cutting. My Stihl trimmer does it to me atleast twice a year or more. All you gotta do is run the needles down gently seated and usually the setting is 1 and 1/4 turns out on both high and low needles. It should start then. Then adjust from there. Lots of videos on that. But anywho. It must be trash or varnish builds under the needle and seat and running it in clears it. Its worked more then 30 or.40 times in my life. If you took it to a shop they will tear it down and sell you a rebuild job every time. Um very seldom needed. Not on old stuff anyway. Most of this new stuff you either cant adjust or need a special splined tool for the job. They cant sell you. But i ordered a full set yesterday for my stepfathers polan and lord noes what else. New Junk. Look for needles you can adjust. Or dont buy it. Or you can simple toss the carb and buy a new chinese one for around 15 bucks. Your call. Note echo blower a couple years ago i bought new had no screws. Ran to rich, no power so i returned it i was so mad. I heard from my local shop Most or them came tuned to lean and burnt up. Check your local pawn shops for the older stuff while you can still get it. Then learn to work on it. Tons of videos!
It’s also a good idea to check the spark arrestor to make sure it hasn’t become gummed up. A little mineral spirits and gentle application of heat with a small propane/mapp torch will clean it right up.
thew splined tools avail from wish china 5 bucks the set landed. Another tip is screw idle well in so enigne will run as u tune. ie low jet adjust till it starts responding freely then back idle screw off. especially handy if youve pull jets out for cleaning. i run the carbs thru a small ultrasonic cleaner its amazing the crap petrol leaves behind in the galleries of carbs.
Hi Folks, don't forget to add gas stabilizer when storing your machine, it is often the source of problems. Also use the best gas you can find, you'll be glad you did. Those small engines are fairly simple to fix, just practice preventive mechanical measures and you will avoid most common issues.
I make this same mistake almost every year, I plan on taking it out one last time before the snow falls but never get to it. Come spring I curse myself every time. For years, before I knew this truth, I had to take my saw in for repair every spring. "The definition of insanity is doing the same thing over and over again and expecting a different result."
Brilliant information put across so well, I have same issue, when opening up the carb to check diaphragms one was wet so reckon it was punctured, looking for a replacement right now?
Love your video keep up the good work. I just got a old chainsaw from somebody I'm going to see if I can get this one running. I gave you a thumbs up 👍🐟💯👋👋👋👋👋👋👋😁😁😁😁😁😁😁😁😁
I have a Husqvarna Rancher 455 sitting on storage for about 10 years. I have not tried to start but I´m sure it won´t . I do not have your skills to do this procedure and will have to replace the carburetor (Amazon $27) if it needs maintenance. Thanks for the nice class.
One thing you missed was to check and see if the fuel filter inside the tank was intact or letting junk go straight to the carb and plug the needle valve. That may have been the root cause of the plugged carb to start with and it will happen again soon if the fuel filter is missing.
No need to buy a carb or gasket set Very seldom will need to need to replace a gasket Even if you tear one and it’s all still there it will still seal ok I’ve even made gaskets from cardboard boxes when working really old engines Just make sure the keys are cleared all you need is cleaner of any band Acid brush A wire small enought to crear the jet Shop towels to dry the cleaning Fluid
Did you notice about 9:44 when blowing air through the one part of the carburetor and a little black speck suddenly appears on the cloth below almost hidden by the index finger. I wonder if that was a clog and was the problem?
Watching from country (Botswana ) i feel very delighted to watch this video, i just bought brand new chain saw but it worked well actual its 2 months kicking well but now its start and switching its self off its not catching up to a good start...help please i don't know what to do but i got lot of farm jobs i have to do?
It is not clear what your question is. Are you saying that it will start but then when it gets hot it will shut off and then you can’t start it? If that is the case it could be that the ignition coil is bad.
If I may, first see if has fuel and fuel lines are good with filters and then go through all these tips as well to ensure you have good working equipment. Good job...
Btw, I strongly discourage blowing compressed air through ports and holes in the carburetor. There are tiny check valves and diaphragms in there that you’ll destroy if you use an air compressor on them.
My experience also is the stone filters break down & causes the grit you see in the carburetor. Switch to a paper filter & this will prevent the trash in the carb. My number 1 tip to all.
My 142 e - series will start with starting fluid but won't stay running. Cleaned the carb, which didn't look bad. As you've stated, this has to be something easy that I'm overlooking. I haven't removed the fuel hose yet, but there's definitely gas in it. I have air and spark, so it has to be a fuel issue. Thanx for the video.
Be careful not to run it on ether… I just use that as a test. There is no lubrication in the ether which can burn up your piston and cylinder wall. Check that there is no water in your gas and also that your fuel filter is not clogged Let us know what you find out
@@helpinguonline Yes sir, I am aware and I never use ether on 2 strokes but as you said, a test. That at least told me it would start. This saw is also 1 of 2 that someone gave me. I'll keep you posted. Thanx for the response.
Very good checking for the problem. I have done exactly what you have done, but it will not start unless ether added, then will run fairly smoothly for as long as it can. Unfortunately when it has been stopped, and you try to start it, it just will not start, wants to but just won’t, have you any ideas.?
You clearly have a fuel delivery problem. Start simple like checking for a clogged fuel filter, clogged air filter, bad fuel line etc. If your brand of saw has a vent line for the fuel tank make sure it is not plugged. If the problem is not something simple then you will have to remove the carb and clean/rebuild it or replace it. Let us know what you find out. Also, be careful not to spray too much ether in it (I only did that little test to verify the problem)... the engine is lubricated by the 2 cycle oil in the fuel and that keeps the piston and cylinder wall from getting scored (ruined). Ether has no lubricating properties in it.
It doesn't take much to clog those tiny ports on those carburetors. In the future... if you drain the fuel and run it out of the carb before you store it for a month or longer you will save yourself from having to do this. Thanks for watching
Great video.Obviously you are very knowledgeable and an asset to society.Please please use latex gloves when using carcinogens.We need you around for awhile.
starter fluid is very hard on small engines, no lubrication in ether/starter fluid, I would start with checking for spark and fresh fuel, then going to the fuel line and filter, starter fluid is best used for spud guns.
Thank you so much for the video. It is fantastic! I have a chainsaw that's doing the same thing. I will try this and see if that works. It has only run 1 time then stop working! Thanks again for a great video!
Thanks for your feedback. You can do it!... and always remember to empty the fuel out of the tank and run it out of the carburetor if you are not going to use it for a while... will save lots of headaches...
Excellent video. did not need to watch it 4 times to get it. lol During the winter I started it every few weeks but gummed up anyway. gas stabalizer mentioned can stay in afterward or must be flushed? someone told me to empty gas after every use.
I got a little Husqy that came with the SxS I bought, it has old gelled up gas in it so I'll use your video as a guide. But tell me what is the best way to clear the crap out of the fuel lines, prime bulb etc?
I just got my Husky 445 started by using a hammer ! It was headed for the repair shop with another $80-$100 bill for a new carb when I decided to tap the carb several times (gently) on both sides while it was still installed. (This worked on my old Gravely lawnmower. ) Evidently the needle valve was stuck closed as i left the saw sitting with gas in it for several months and tapping the carb loosened it. I have exclusively used TruFuel but it still must have gummed up the carb. From now on, I will drain the gas and run it dry until I use it next time.
This is a very helpful video. I just bought a used husqvarna 550xp that wont start. Pulled the muffler and the piston and cylinder look good and seems to have good compression. Has excellent spark and new spark plug. I can crank on it till my arm gets tired and pull the spark plug and it's not wet with fuel. I changed the fuel filter and put fresh mixed in it. I'm leery of fooling with that weird autotune carburetor, but I guess I'm gonna have too.
Pressure test the crankshaft seals on the old Macs we use to use max of 10psi threw threaded hole in homemade port blockoff plates look for air leaks at crankcase and seals with dishsoap soapy water. This video should help a lot of people understand the steps to go through keep up the good work you're very good at keeping on point in your video.
Great video my saw is a husky 257 there are two small adjustment screws on the left side of the saw one marked L and H how do you adjust them or should you?
If your saw is running well leave them alone. If your carburetor needs adjustment at some point in time you can adjust them. The L is for adjusting the low side (idle mixture) and the H is for the (High mixture). You want to be careful when adjusting the high side. You want it running a little rich and not perfectly smooth. Watch a video on that before you adjust... and a chainsaw is a little different than other 2 cycle engine carburetor adjustments (ie a weed eater... etc.).
I just got a new Mark II 16 inch only 165.00 . Somebody did a return . Ran for a while then died will not start . Spray starting fluid into spark plug no spark no kick . I disconnected wire to shut off nothing so I say its a defect coil. What you think ? Did you screw out low and high adjustment screws also ? Factory set I noticed so I leave them alone.
Sorry you are having trouble. It takes fuel and spark for your engine to run. If your coil is bad you should notice a weak spark, intermittent or no spark typically... or when they are going bad the engine can sometimes run but quit when it gets warm. It is hard to say from here what your problem might be but when you are diagnosing keep in mind those 2 simple things... Have to have spark and fuel... and that should help you narrow down your problem and lead you to the fix. You can check out my video where I removed a coil and tested it at this link: th-cam.com/video/Z0PLBL6WnqU/w-d-xo.html Hope that helps and you can get it going.
@@helpinguonline Thank you for your help. I will check out the coil. Sometimes start right up then dies out seems like no spark. I did starting fluid no go then . Keep pulling at it just might kick then . I feel though spray fluid SHOULD start right away if some kind of spark. When I pull plug out all wet . Thank you .
Hi, I am a pensioner who lives in Scotland and creates clocks and tables etc. from felled tree's, I have never cut/felled a tree and I have no desire to do so! There is enough wood lying about our woods/forests that are left too rot from those who have rights to make a living from cutting down contaminated/rot tree's. I do not use my saw much, but this video of your was helpful information for future reference/s for me in which I do hope I do not encounter! Many thanks!
Another piece of advice if your not going to use the saw for a few months drain the fuel from tank (if youve got a petrol car throw it in it wont hurt the car) then prime whats left thru system start and run saw till it cuts out. When you pull it out refuel reprime away ya go.
I live on 10 acres of oak. They are always falling or loosing big branches. If I don't cut them up, the fire danger becomes enormous. I use my saws almost daily.
I took the same saw to a repair shop a few years ago and they told me that I needed a new carb, $85 bucks later I was good for a while. But I didn't realize that the alcohol in gas will turn to varnish if you don't use it up. I am determined to fix this problem this time, as I also did with my lawn mower twice. Now I buy gas with no alcohol in it. Excellent video, Thanks

no, knowledge is power, information is information 👌
Straight to the point and no BS. Thank you!
Just a tip....While you have the carb apart, hold the diaphragm up to a bright light and see if it has a hole or a crack in it.
make sure it clicks too
@@newt66c33from what I see on other repair videos you specifically don't want it to be clicking in and out. That means it is stiff and needs replaced.
@@newt66c33100% wrong! If it clicks, it’s past toast. Bin it. They should be very soft and supple. As soon as they start to stiffen; they should be replaced.

Most 2 stroke oils have stabilizers in them already! At least the higher grade ones do
DO NOT store gas in any machine over winter! Run it dry, buy fresh non-ethanol gas when ready to use again-
Totall TRUTH. I’d rather do a little preventative action that not and deal with an issue that didn’t need to become a problem.
I make this same mistake almost every year, I plan on taking it out one last time before the snow falls but never get to it. Come spring I curse myself every time. For years, before I knew this truth, I had to take my saw in for repair every spring. "The definition of insanity is doing the same thing over and over again and expecting a different result."
Husqvarna gas has Stabilizer in it by default & can sit for up to 2 years without issue. Cost more but you can relax when stored during winter.
You make it look EZ. You saved me $$$ to the shop. Thank you for the awesome video.
Glad to hear it helped
Brilliant information put across so well, I have same issue, when opening up the carb to check diaphragms one was wet so reckon it was punctured, looking for a replacement right now?

If i could give it two thumbs up I would. Thanks. Shame the carb is so difficult to get to.

Thank you very much now I can get out that polan saw and replace fuel lines and clean the carb with confidence
Its a most normal problem , carburator have so smal hole ,and smal filter not need mytch dirt, too stop petrol .
Good instruction 👍
Excellent, well explained. Agree with the last person's comment, quicker and cheaper purchasing a new carb.
Thank you for the video dude you ROCK!! By the way awesome music in the background,🎵🎶🎵😊
No problem 👍
If you like that music, you are easily entertained!😂
One thing you missed was to check and see if the fuel filter inside the tank was intact or letting junk go straight to the carb and plug the needle valve. That may have been the root cause of the plugged carb to start with and it will happen again soon if the fuel filter is missing.
bad oil is mostly the problem as it jells up
You should consider buying a carb. They are often cheaper than a rebuild kit. It was the case for my Husqvarna 445e.
No need to buy a carb or gasket set
Very seldom will need to need to replace a gasket
Even if you tear one and it’s all still there it will still seal ok
I’ve even made gaskets from cardboard boxes when working really old engines
Just make sure the keys are cleared all you need is cleaner of any band
Acid brush
A wire small enought to crear the jet
Shop towels to dry the cleaning Fluid
Did you notice about 9:44 when blowing air through the one part of the carburetor and a little black speck suddenly appears on the cloth below almost hidden by the index finger. I wonder if that was a clog and was the problem?
I saw that too!
Thank you very much for giving an idea how to maintain my chainsaw...

When you spray starting fluid in the carb you need to hold the throttle wide open so the fluid goes to the cylinder

@@helpinguonline Yes sir, I am aware and I never use ether on 2 strokes but as you said, a test. That at least told me it would start. This saw is also 1 of 2 that someone gave me. I'll keep you posted. Thanx for the response.
Love my EGO electric saw. Two batteries keeps me going all day.
I have the same saw,/ same problem, thank you so much, huge help
Glad it helped
Love your teaching
i had my fuel lines hook up wrong from my primer bulb thanks for your video
Glad it helped
Very good checking for the problem. I have done exactly what you have done, but it will not start unless ether added, then will run fairly smoothly for as long as it can. Unfortunately when it has been stopped, and you try to start it, it just will not start, wants to but just won’t, have you any ideas.?
You clearly have a fuel delivery problem. Start simple like checking for a clogged fuel filter, clogged air filter, bad fuel line etc. If your brand of saw has a vent line for the fuel tank make sure it is not plugged. If the problem is not something simple then you will have to remove the carb and clean/rebuild it or replace it.
Let us know what you find out.
Also, be careful not to spray too much ether in it (I only did that little test to verify the problem)... the engine is lubricated by the 2 cycle oil in the fuel and that keeps the piston and cylinder wall from getting scored (ruined). Ether has no lubricating properties in it.
Great Video, have a Rancher 450 that probably has same problem, hasn't been run in a couple years and assume it's all gummed up.
It doesn't take much to clog those tiny ports on those carburetors. In the future... if you drain the fuel and run it out of the carb before you store it for a month or longer you will save yourself from having to do this. Thanks for watching
while your at it remove the blocked muffler spark arrestor and open low jet just a smidge as its not revving quite right.
Great video.Obviously you are very knowledgeable and an asset to society.Please please use latex gloves when using carcinogens.We need you around for awhile.
Thank you
starter fluid is very hard on small engines, no lubrication in ether/starter fluid, I would start with checking for spark and fresh fuel, then going to the fuel line and filter, starter fluid is best used for spud guns.

Well done and you have it explained exactly , thanks!
Thanks... Glad it was helpful
not quite Fritz...
FABULOUS INSTRUCTIONAL VIDEO !! THANK YOU !!
Thanks for the feedback. Glad it was helpful!
Thnks for your teaching.
Thank you for your visit
Thank you so much for the video. It is fantastic! I have a chainsaw that's doing the same thing. I will try this and see if that works. It has only run 1 time then stop working! Thanks again for a great video!
Thanks for your feedback.
You can do it!... and always remember to empty the fuel out of the tank and run it out of the carburetor if you are not going to use it for a while... will save lots of headaches...
i have H 240 also. Never use ethanol gas and if it wont start open the gas cap then retighten. This Chainsaw design gets vapor locked easily.
Thanks. I was cheering for you also
Thank you!
L like this vidio very much keep it going for us to learn more thank you
I appreciate your feedback
Excellent video. did not need to watch it 4 times to get it. lol During the winter I started it every few weeks but gummed up anyway. gas stabalizer mentioned can stay in afterward or must be flushed? someone told me to empty gas after every use.
Best advice is to empty the tank and run the fuel out of the carburetor if it will not be used for a while...
Very good instructional video.
Thankyou.
Glad it was helpful!
I got a little Husqy that came with the SxS I bought, it has old gelled up gas in it so I'll use your video as a guide.
But tell me what is the best way to clear the crap out of the fuel lines, prime bulb etc?
Your fuel lines and primer bulb are probably not clogged. I would make sure the fuel filter and carb are not all gummed up though.
So you didn't need to change the fuel filter or tune it up afterwards? Just wondering.
That was a big help. Thank you so very much
Thank you mines had some problem may be the caburator .I wil try to repaired how you did...
Did all the same to my Husqvarna 440. Ended up getting $18 kit on Amazon w/ carb, fuel lines, primer, plug & filter.
Fired right up.
Way to go
Thanks your information is great, I feel more confident to mess with mine.
You can do it!
Excellent Video, Thanks, Ed Daughrity
Very welcome
Check to see if you can get the new metal spiral diaphragm for the carb. You will never need another.
I just got my Husky 445 started by using a hammer ! It was headed for the repair shop with another $80-$100 bill for a new carb when I decided to tap the carb several times (gently) on both sides while it was still installed. (This worked on my old Gravely lawnmower. ) Evidently the needle valve was stuck closed as i left the saw sitting with gas in it for several months and tapping the carb loosened it. I have exclusively used TruFuel but it still must have gummed up the carb. From now on, I will drain the gas and run it dry until I use it next time.
thank you for sharing t his very good video.
Glad to hear that
Chainsaw
I have a makita saw that’s hard to start.same principle applies here. Thanks for the video
Very nice work
This is a very helpful video. I just bought a used husqvarna 550xp that wont start. Pulled the muffler and the piston and cylinder look good and seems to have good compression. Has excellent spark and new spark plug. I can crank on it till my arm gets tired and pull the spark plug and it's not wet with fuel. I changed the fuel filter and put fresh mixed in it. I'm leery of fooling with that weird autotune carburetor, but I guess I'm gonna have too.
Pressure test the crankshaft seals on the old Macs we use to use max of 10psi threw threaded hole in homemade port blockoff plates look for air leaks at crankcase and seals with dishsoap soapy water. This video should help a lot of people understand the steps to go through keep up the good work you're very good at keeping on point in your video.
Great job - very helpful - thanks 👍
Glad it was helpful!
done with small 2 cycle engines, impossable to clean the carb, just bought a dewalt electric chain saw and love it
excellent job sir
thanks
thank you for your good sharing...
Thanks for visiting
Great video my saw is a husky 257 there are two small adjustment screws on the left side of the saw one marked L and H how do you adjust them or should you?
If your saw is running well leave them alone. If your carburetor needs adjustment at some point in time you can adjust them. The L is for adjusting the low side (idle mixture) and the H is for the (High mixture). You want to be careful when adjusting the high side. You want it running a little rich and not perfectly smooth. Watch a video on that before you adjust... and a chainsaw is a little different than other 2 cycle engine carburetor adjustments (ie a weed eater... etc.).
Thank you for your insight
Great Job!!
Thank you!!!! Thorough instructions! I love it :)
Glad it was helpful!
I’m a new subscriber and I’m working on a235E that won’t start I just have a cuestión what is the gap on the ingnition coil thanks
about 0.012 inch... but I always use a business card which is about the same thickness.
Very good buddy 👍😊👍 Thanks a lot
I just got a new Mark II 16 inch only 165.00 . Somebody did a return . Ran for a while then died will not start . Spray starting fluid into spark plug no spark no kick . I disconnected wire to shut off nothing so I say its a defect coil. What you think ? Did you screw out low and high adjustment screws also ? Factory set I noticed so I leave them alone.
Sorry you are having trouble. It takes fuel and spark for your engine to run. If your coil is bad you should notice a weak spark, intermittent or no spark typically... or when they are going bad the engine can sometimes run but quit when it gets warm. It is hard to say from here what your problem might be but when you are diagnosing keep in mind those 2 simple things... Have to have spark and fuel... and that should help you narrow down your problem and lead you to the fix.
You can check out my video where I removed a coil and tested it at this link:
th-cam.com/video/Z0PLBL6WnqU/w-d-xo.html
Hope that helps and you can get it going.
@@helpinguonline Thank you for your help. I will check out the coil. Sometimes start right up then dies out seems like no spark. I did starting fluid no go then . Keep pulling at it just might kick then . I feel though spray fluid SHOULD start right away if some kind of spark. When I pull plug out all wet . Thank you .
Nice video I always put fresh gas.
Wow excellent video,
Wow..That was cool...thank you sir
Very welcome
You made it. That's great.
Hi, I am a pensioner who lives in Scotland and creates clocks and tables etc. from felled tree's, I have never cut/felled a tree and I have no desire to do so! There is enough wood lying about our woods/forests that are left too rot from those who have rights to make a living from cutting down contaminated/rot tree's. I do not use my saw much, but this video of your was helpful information for future reference/s for me in which I do hope I do not encounter! Many thanks!
Another piece of advice if your not going to use the saw for a few months drain the fuel from tank (if youve got a petrol car throw it in it wont hurt the car) then prime whats left thru system start and run saw till it cuts out. When you pull it out refuel reprime away ya go.
I live on 10 acres of oak. They are always falling or loosing big branches. If I don't cut them up, the fire danger becomes enormous. I use my saws almost daily.
