I've replaced those diaphragms that were to the point that they crumbled! It's a wonder the engine ran as long as it did. Another top-notch video Don, thanks for sharing it with us! Rev. D.
Just a week ago I got a "rescue trimmer" given to me because it was running gas out the muffler. (FS 55 K). I got the power head, trimmer head, blower, and edger attachments for free. Not knowing that it probably was just the diaphragm, I bought a Oregon brand complete kit and cleaned the carb and it runs like new. I rarely have to buy any outdoor equipment as it is usually given to me or I see it on the side of the road waiting to go to the landfill. Thanks for the very good info on this problem and the advice on the needle arm setting.
Great insight. Thanks for this video. I had a Hitachi leaf blower that also had a stiff metering diaphragm that would flood very easily. I ordered a new carburetor and came across this video. I was inspired to actually bent the metering lever down slightly. I had nothing to lose since I have a new carb on the way. When I reassembled the old carb, it worked like a champ. Cold starts too. Thanks!
Its always good to sit with a coffee and clean hands in the study and watch you showing what I need to be doing out in the shed when I finish the coffee.... You give the preview and we go out and do the same as you've shown... Excellent videos as always. Thank you. Just a tip I'd like to share with people. I do this every season and especially with the line trimmer. I remove the exhaust system, burn it in a wood fire until its red and then blow it out and put it back on with a new gasket. The very first step when I have starting and 'bogging' problems and it fixes them every time.
As a general rule any more, I replace the entire carburetor depending on model. I like to replace the primer bulb if it's cloudy as that is important to see if air is also entering the system. These days, 90% of what I fix is fuel related anyways.
90 percent of the time I don't bother to repair the carbs, I just replace them as well. I use the Chinese knockoffs when the machine is budget grade consumer level equipment.
Great tip Dony! I guess having ethanol in the gas has something to with that. I would just replace everything at that point, easy and cheap enough. Thanks! 👍👍. Have a great weekend.
Thanks for the video donyboy73. Knowing about the gasket going on first before the diaphragm is something I would have not payed attention too. I'm going to be doing some work on my STIHL weedeater soon. Thanks again.
Another great video and shows a pretty common issue that I see. First: I'm not a professional repair guy like "donyboy73" here. However, I do work on a lot of these little machines and have come to MY OWN separate CONCLUSION that the Ethanol Gas they sell today has a lot of BAD REPERCUSSIONS for these little guys parts. I really didn't see a lot of these diaphragms go HARD like this until people started using the Ethanol Gas. INTERESTING NOTE: I forgot about a 5 gallon can of Ethanol Gas for a couple of years and when I found it I could see two different layers thru the side so without moving it I dipped a rag down and the top layer was just pure water. It had separated and was now on top of some rank gas but this find was an eye opener for sure...Just sharing what I found. I suggest taking the time to find Ethanol FREE gas and using the MID Grade or even Premium and only mixing up enough for a few months worth. Actually these 2 cycle manufacturers suggest a min of 89oct and Ethanol FREE for the pre-mix for their engine. JUST My opinion...
Maybe that's my problem. I used to take care of my lawn before ethanol gas came along and hardly had any problem. Then I decided to get new equipment and start doing my lawn again, and a year later I'm having trouble with the trimmer.
Hey Don Another great tip. I had an FS40 last week where the low speed screw was very difficult to adjust and the high speed screw had no adjustment whatsoever. Turned it in nothing, out nothing. The diaphragm was hard too. Instead of rebuilding I replaced the carb. However, the OEM carbs from my local dealer last year were $65 Can, this year, $94. Should I have tried to clean and rebuild? I haven’t had much luck with carb kits and don’t like to buy Chinese. Cheers
I simply do not understand why they don't install bowl top carburetor on 2-engines, they always do those pesky diaphram carburetors. And all you get with that is failed diaphrams due to the ethenal in the gas, which forces us to have to buy kits all the time. That, or do what most people do, buy 15 dollar replacement carburetors off Ebay. When I bought my new Honda trimmer, I made sure to buy a complete carburetor and fuel parts replacement kit. I wanted to have all of it on hand, for when the inevitable happens. Good to see you Don, thanks for making such awesome video's!
Well saw, trimmer, blower etc carbs need to be able to be run in all positions, ie upsidedown, on there side etc. That's the unique feature these diaphragm carbs have.
Donyboy73 I have a question. I got the Kombi unit for stihl. It’s the km56 rc-e. I recently purchased the fs-km attachment. It came with the grass blade for. Can I put the knife blade on it instead of the grass blade for cutting mulch. This attachment is for cutting brush. Why or why not? Stihl dealer said yes. However, on website says no not approved. Very odd
The 56 engines use a cable shaft, not a solid steel shaft. You can only use brush blades that whirl out when RPM is applied, not the solid brush blades with no give because repeated shocks will damage the cable drive shaft.
@@TheKrayusKorianis so you wouldn’t chance it? It fits on like a glove. I thought it was more of a safety hazard than anything. But I think it’s now of the motor head engine like you said here. If it breaks it I’ll upgrade to a pro model
@@appleztooranges Stihl dealer and tech here. If you use a brush blade on it, over time the weight and centrifugal force from the blade will cause the flex shaft to fray and unwind from the clutch drum. I see this at least once a month. It's not an overly expensive fix at my shop, but this can vary by dealer. If you just have a quick job to do, it probably will not destroy the shaft at first, but repeated use most certainly will.
Have put new complete cardy kit nidle valve diaphragms etc. Pressure tested carby over night and is perfect. Before l try to start it air filter is saturated. Have to hold throttle flat out no choke and takes about 8 pulls to fire then start. Also fuel level seems to drop over night. But runs OK. Rotary zama carby . Bit different than the one in your video.
I don't normally comment, but because you've taken the time to clearly show everything, explain the step-by-step process and also the REASONS WHY each step is necessary, which has also given me insight how it all works, you've just earned yourself a subscriber. Thank you for this video. Extremely helpful and well done.
top stuff Donny mate cheers from Australia to Canada and Stay Safe to and i have a Stihl FS 55 RC and it,s very similar to this one to but just the next model up from my view.
Sometimes it’s the diaphragm gone hard but I could see in this particular machine the glue had let go on the welsh plug. This could cause a few different issues. If the glue jams open the needle then it will flood uncontrollably. If the the glue gets sucked into high speed main jet it will run lean and not rev up. Also since the glue has come off welsh plug it may leak past and bypass straight into transitional ports. In that case it’s always better to fit another OEM carburettor 👍 Cheers Donny 🍻
Hey Don, nice video. I have a question. Once you you took the fuel line off,which drained the fuel from the primer bulb. Did you Prime the bulb after replacing the metering diaphragm or just started with the throttle open and choke off?
No long winded intro and sub and like and stuff! You've earned a subscription even if this is the only vid I watch. Doubt it though, got an idea you're gonna have the info I need to repair a petrol generator.
On my brothers Honda GX35 line trimmer it had the opposite effect because it was running lean so maybe not enough fuel was entering the fuel chamber,I don't know. The metering diaphragm was petrified but it wasn't letting enough fuel enter the fuel chamber in the carburetor, maybe it was actually a bit bulged. A leaking main jet check valve will also cause flooding & the engine will also bog down as well. On some carburetors they also have hidden fuel mixture adjustment screws !
It is mostly the OEM manufactures themselves, they put it out for bids ,the most economical manufacturer receives the contract or they meet the price point that the OEM's set out for the part .In my trade the parts supplier has moved from China to another poor country.I wonder why, the price point that the consumer will except and buy.If products were made in a higher price point country consumers would not buy it,The ones that did would take extra care of these products and keep them longer. The companies can't have that. that does't make their world go around .
You're kidding right? How is it so sad when Americans got what they wanted? When Americans don't care about buying American because it costs $0.50 more, the only other option is to hope for some government "solution", like a bunch of protectionist tariffs, and if you look up the history of protectionist tariffs, that has economic consequences too. In some countries, people tend to buy local out of a sense of pride or patriotism. In America pride is buying Chinese baseball hats with political parties logos on them and waving Chinese made US flags. Americans love America, they just don't care too much for other Americans.
Hey, Donny, thanks for the tip. I recently replaced the carb on an FS 45 and having a problem adjusting the idle, which you, mention toward the end of this video. When you mentioned the idle adjustment with the mechanical screw, we’re you referring to the large screw in front of the fuel tank which does adjust when throttle cable travel - my problem seems to be that the screw vibrates out of position. Thought that I’d seen one from your videos before on the carb adjustments, but can’t find it now.
I had that vibrating problem on my old br420 backpack blower thats how i bought it used so Id set the low and high to the right spot and they kept vibrating loose the carburetor is good but something wrong with the high and low screws on the carburetor so i replaced the carburetor and put a zama one on it the original carburetor was a stihl walbro. Im still working on the old br420 seems like it needs a new coil its got a new carburetor and it works fine but wants to keep shutting off so i think the old coil is burning out it still needs a spark arrestor put in
I had a flooding problem. Just replaced the diaphragm & gasket and now the bulb wont fill. I'm sure I have the correct diaphragm. Put the old one back and the bulb works fine. Any thoughts?
I have an old Stihl FS110. If the primer bulb is about 1/3 full, I depress it one time and then walk away for maybe 5-10 minutes. When I come back and do the normal start procedure, it will usually start on the first pull. Just about anything else, forget it.
I don't repair carbs any longer. I just replace them. Been burned on a repair like this only to have some other carb problem once the engine is restarted. Good video though!
i have a almost brand new ms261 2012 stihl chainsaw i used it 3 times for like 10 mns each time are they worth anything?its a pro saw i remember i paid alot back then.its been stored with no gas in it since 2013 in my bedroom closet
@@aussiehardwood6196 im in minnesota and ya I would think about selling it.lots of people wanted it for free around here so thats why i hid it for so many years i had many 150 dollar offers but no lol
Really good video Don!!! I had to tap the like button a bunch of times for this video because it kept highlighting the thumbs down instead but finally got the thumbs up. Hope that doesnt screw up ur stats. What the difference between an fs 55 & an fs 55R? I have the fs 55R and stihl dealer seemed puzzled by that.
thanks for the video donnyboy about do a full rebuild on my 16 year old echo srm2305 carburetor & new fuel lines thought was time to give it some luv seem its done me well for 16 years with out any major dramas other than my time to service it
Hey Donny, I remember when Steve's small engine did a video showing where the hidden adjusters are on carbs like that. Could it be the same for this one too? Anyway, good to see you're doing great and great vid
Cars I used t have with a carburetor which had flooded were easily started by mashing the accelerator to the floor while cranking the engine. Same principle.
Need help!!! My Ryobi blower runs good at full throttle. But it turns off at idle. After that it becomes almost impossible to get it started. Any tips?
Mines an echo and its been serviced recently already like last week but the diaphram was not replaced.... and now its doing the same thing....so, is this the same issue but different part #
Right ,, but the whole Carb goes for like $10-12 , may as well replace the entire unit,,however its good to know what the actual cause was ,,thx for share
Thanks for the videos! I have a "weedeater" brand 2 cycle edger that doesn't run unless I pull sparkplug and squirt gas into cylinder, and it only runs till that gas is burned up. Gas was ran dry the last time it was running. I guessing it is a carb issue, any ideas? Thanks for any help you can offer, and yes I have been a subscriber for a couple years.
Hi Dony, my machine sat in the sun one day and there was some gas leakage. I checked the diaphram and it seems fine. With this machine a repair kit costs the price of a new machine and China does not make one. I hate to toss this one out but I have checked spark, filters, everything, it sparks like mad and even injecting some fuel I got nothing but a backfire sometimes, no firing at all. Is it possible spark timing can be out? Does the leaking fuel indicate the diaphram is definitely shot because it feels very soft and is not broken. Maybe I should bend the lever down just a tad? HELP :)
Hey man. I just got a trimmer, it was not used for 1 year and fuel was all that time in the tank. Now it doesnt start. Do you have any tips what it can be/how to fix? Thanks
@@donyboy73 Wow thanks for fast reply. Yeah thought so (that carb might be clogged etc). Ok ordered new carb, spark, petrol pipes. Just for good measure. Thanks man.
Great vid.. I wanted to ask about the Echo GT 3000.. am i correct in saying a perished primer bulb would cause fuell leak out of what i think is some sort of breather... Or would i be best to replace the whole diaphragm,fuelines etc? (My apologies, i think you get what i mean.. girl explanation ha ha!! sorry...im a late starter in this fix it caper !)
@@donyboy73 thanks for the reply.. i'll be stoaked if its just the primer bulb.. Cheers for making these easy to understand clips like these for people that want to do things for themselves. 😁

Pretty sad that neither Canada or the US can’t compete in making the diaphragm. We’re just making China richer each day.
That's a Chinese carb made by a Chinese company. You would expect for the consumables to made in China also.
Who is going to work for Chinese wages? You?
It is mostly the OEM manufactures themselves, they put it out for bids ,the most economical manufacturer receives the contract or they meet the price point that the OEM's set out for the part .In my trade the parts supplier has moved from China to another poor country.I wonder why, the price point that the consumer will except and buy.If products were made in a higher price point country consumers would not buy it,The ones that did would take extra care of these products and keep them longer.

Mines an echo and its been serviced recently already like last week but the diaphram was not replaced.... and now its doing the same thing....so, is this the same issue but different part #
My Stihl fs38 has a rough idle. Runs great at full throttle. Just has rough idle. Replaced spark plug. Any ideas? I use ethanol free gas
try cleaning muffler screen also
Very nice!
Right ,, but the whole Carb goes for like $10-12 , may as well replace the entire unit,,however its good to know what the actual cause was ,,thx for share
some of the cheap carbs are hit and miss
You are the best 😊 this helped so much
I have a Stihl BG 55 blower, as soon as I push the primer bulb once, it's flooded with pure gas dripping from the muffler
Where u get the tools from.?
How did or do you find the right metering diameter for your model? Say like mine is a black max 25cc?
Thanks for the videos! I have a "weedeater" brand 2 cycle edger that doesn't run unless I pull sparkplug and squirt gas into cylinder, and it only runs till that gas is burned up. Gas was ran dry the last time it was running. I guessing it is a carb issue, any ideas? Thanks for any help you can offer, and yes I have been a subscriber for a couple years.
sounds like a carb issue, it might be easier for you to just replace entire carb
@@donyboy73 K, thanks for replying, I have to pull carb and see about a replacement.
How does the meter raise or lower?
Hi Dony, my machine sat in the sun one day and there was some gas leakage. I checked the diaphram and it seems fine. With this machine a repair kit costs the price of a new machine and China does not make one. I hate to toss this one out but I have checked spark, filters, everything, it sparks like mad and even injecting some fuel I got nothing but a backfire sometimes, no firing at all. Is it possible spark timing can be out? Does the leaking fuel indicate the diaphram is definitely shot because it feels very soft and is not broken. Maybe I should bend the lever down just a tad? HELP :)
Does this apply to gas leaking into air filter.
Hey man. I just got a trimmer, it was not used for 1 year and fuel was all that time in the tank. Now it doesnt start. Do you have any tips what it can be/how to fix? Thanks
it might need a new carb kit
@@donyboy73 Wow thanks for fast reply. Yeah thought so (that carb might be clogged etc). Ok ordered new carb, spark, petrol pipes. Just for good measure. Thanks man.
My FS200 ,the Gaz is boiling in the carburetor after +- 5 minutes of used, What cause this ?
Good job. Frank
Where can I get a new ignition module for a poulan pro 6.75, i looked on amazon and couldnt find one specific for that mower ...
try your local small engine shop
Thank you brother
Great tip Dony! On foam air filters like that stihl, do you lightly oil them after cleaning or put them in dry? 🇺🇸👍Roger
i put them on dry
@@donyboy73 thanks Dony!
Great vid..
I wanted to ask about the Echo GT 3000.. am i correct in saying a perished primer bulb would cause fuell leak out of what i think is some sort of breather...
Or would i be best to replace the whole diaphragm,fuelines etc?
(My apologies, i think you get what i mean.. girl explanation ha ha!! sorry...im a late starter in this fix it caper !)
you can try just replacing bulb, if it still leaks replace fuel lines and grommet as well
@@donyboy73 thanks for the reply.. i'll be stoaked if its just the primer bulb.. Cheers for making these easy to understand clips like these for people that want to do things for themselves. 😁
I thank you for the help 👍🏼
