I have a Stihl FS 110. I bought it at least 8 years ago and it's never given me any difficulty until a couple of days ago. I intend to purchase a carburetor kit to replace the one that's in it. The kit also comes with a spark plug, gas filter, air filter and other parts from Amazon. I noticed that it would start and work well until I needed to shut it off for a few minutes. It used to restart it without any problems but lately, it wouldn't restart. I cleaned the filters and spark plug and it's working a lot better. I started using that premixed 50 to 1 gas that is sold in Home Depot. It doesn't have ethanol and that's the main reason that my machine has lasted so long. I use it quite a bit since I live in S. Calif. I have 2 and a half acres of lots of weeds.
I'm going to guess that the original carb is having some difficulties delivering fuel like it supposed to so a replacement Carb is the best option. Hopefully it works out for you.
I'm a small engine mechanic thears no reason for this to happen to a stihl trimmer i own sthil products & I make it a point of servicing all my equipment that's why at the end of the day I take the time to clean up the equipment have it ready for the next job I own the fs90r trimmer sthil ms290 chain saw & the ms441c magnum with a 25in bar & the br600 sthil back pack blower nobody is allowed to use eaney of my sthil equipment ever so don't even think bout asking
As of 2023, a top end rebuild kit costs about $30. I’m not a small engine guy and never rebuilt anything and it took me about 45 minutes to rebuild the top end of my FS80. Carburetors, if you need one, cost around $15. It’s much, much cheaper to fix one of these than buy new. BTW, that fuel looks exactly like my mixed gas using Stihl HP at ~45:1. I doubt it was bad gas or low oil. If you take the piston out, you can tell from a few different failure modes based on where the wear marks are (intake side vs exhaust side, e.g.).
even the inexpensive trimmers can last a long time if people would use only ethanol free gas and correct mix radio and before storage for the winter, drain all gas an and dry carb. on carb, the metering diaphragm dries out of shape in long storage and when it's replaced,95% of times it's replaced with a wrong one that doesn't have the same size center metal stud. that means the lever will never completely close and carb will not run correct no matter how much adjustment.
I'm leaning towards a carb adjustment issue, Either there's too much fuel or not enough. but if I had to guess, theres too much fuel because warm engines don't need the extra fuel to stay running.
Hello-My 110R is a great trimmer,but, even with great maintenance, my machine warms up and will not start. Then when it starts up after many tries it will not throttle up -take a few minutes to come up to full throttle-what can be the problem-the shops don't know? thanks
@@INSIDEHOUSEGARAGE the other thing id check are the seals on crankshaft .jus visually note if its oily around it cos air fuel mixture is transferred thru dry crankcase into combustion chamber n if seals r leaky thn it probably wont start also.jus som pionts to kip in mind
I have a stihl fs91r trimmer and it quit today when I was using it full throttle when I was edging a yard. I had it on its side kind of over my shoulder since I was edging but it lost power and died. Started it again and it ran for a few seconds and it died again. It’s only a few weeks into the season and it’s a brand new trimmer why would it do that?
what probably happened is the way you were holding it the trimmer caused the gas to go into the tank Vent. That would keep air from entering the tank and not allow the Fuel to make it to the carb. put the trimmer back on the ground and open the gas cap, close it again, prime the fuel system and then try starting it.
Stihl, Echo, and Husqvarna last longer because Weed Eater and MTD stuff such as Yard Machines, Yard Man, Troy Bilt, Craftsman, Murray, Bolens, and Remington is poor quality
I am arion I am 12 years old ,I saw my grandfather had a Murray 22 mower and It weren't starting ,so I watch some of your vids and I fixed it,then he had a dunsh laser brush cutter so I tried to start it but it didn't I Chang the spark plug ,new gas new carb but still won't start .Can u give me some advice
@@INSIDEHOUSEGARAGEI’m trying to get better at mixing gas but I thought it might’ve been easier just to mix 40:1 for all of my equipment because I have some equipment that requires 40:1
Have one that’ll run great opens up and stays running until it gets hot then it’ll shut off but as soon as it cools it’ll do the same thing anyone in the comments know what it could be? Thanks
@@INSIDEHOUSEGARAGE could you post a picture of that vent? I have the same weedeater that will not idle. It has a round grommet for each line going to the tank but there is seepage around at least one of them. I don’t remember ever seeing any other round part connected to either fuel line.
@@rickeykeeton4770 if you only have two fuel Iines with grommets, and not a third line, that means your Fuel cap has then incorporated in it. Do you have a third fuel line?
So I'm calling a misdiagnosis on this one. It started and ran on choke. as soon as you turned choke off it stopped. Classic carb issue not getting enough fuel. Low compression wouldnt start at all.As it heats up you will get higher compression too. clean carby and retune. Also some 2 stroke oils dont have the blue dye in them doesnt mean fuel is not mixed. pour some on a pane of glass let it evaporate and see if there is oil residue.
They last longer because they are built better. I still run my FS 85. Wife got annoyed from the clutch bell sound, so last year I bought a brand new Troybilt. It lasted two uses and was nothing but problems. EVERYTHING broke. For the FS 85 all I do is run Amsoil, clean filters, grease gearbox and keep the carb tuned. Runs like a champ.
I often wondered what made that ding a ling bell sound in my Stihl hl75 hedge cutter. Never knew it was the clutch! I could listen to that bell sound all day.
Poor Stihl trimmer I had to buy another echo pas 225 today because my old echo pas 225 blew up today It was a sad day today I love ur videos man keep up the good work it’s a shame people don’t take care their equipment
Danged if I know why so many people with 2-stroke engines insist on running them with no oil in the fuel. "I'm only using it once, it doesn't matter." Yes it does! If you have a damaged 2-stroke, and it still has some compression, you can sometimes get more use out of it (sometimes a lot more) by adding more oil to the gas. For example, if it's normally 40:1 or 50:1 fuel-oil mixture, try using 25:1. The engine will smoke more, but the extra oil will help seal small gouges in the cylinder wall, giving better compression and allowing you to keep using the engine. Also, low compression doesn't always mean the engine is completely trashed. It might just mean the piston rings are stuck, and if you can get it to run, running it hard for a while may loosen the rings. In an extreme case you'll have to dismantle the engine to free the rings if they're really glued in with deep-fried carbon deposits.
One time I had entered in a repair shop and asked the owner why he had a lot of trimmers in the floor;he told me that some brick headed customers use their 2-cycle trimmers with only gas (no mixture)the look of my face was priceless...
The similar problem even after I had professional service from a trusted location. what I found was the tank filter we floating still connected to the tubing so I was wondering if I'm just sucking air. Took the tank off and carefully push it back in making sure it was at the bottom of the tank and now runs better than it has in years. If it happens again I might spring or something to add weight to the rubber hose to keep the filter to the bottom tank.
It's the build quality and like a painter said that had a BOSE Wave Radio on the job; 'I figured if I paid a lot for it, I'd take care of it'. This is how I got my MS 440 Magnum saw. A dose of straight gas. BUT a OEM top end replacing, jug, piston and rings, cured that problem. Around $350 BUT a cheap price to pay for a $1200 saw. Stihl runs fine. Sorry about that one but......................! Blessings!
Very sad. Was a great trimmer and not cheap. Reason for possible damage as you have pointed out, accidently using straight gas, wrong mix in gas can, mixing wrong ratio fuel/gas in gas tank of trimmer (yes, I have heard of people doing that) or loaning equipment to friends and neighbors. Never loan out your power equipment. It will not be the same when you get it back. My stihl is over 15 years old. I did have to replace the coil last year. It still is running strong.
My father gave me one piece of advice that I have followed religiously. Loan out your wife if you’re so inclined but never loan out your power equipment 😆👍
I have a FS 90 R and work all day, everyday, for over 2 years. I bought 91 R and did not like it. Its heavier and I don't get the same feeling. The 90 has the same problem as the one on the video, it won't stay on unless on the choke. I wish they continued the 90 R instead of the newer models. Great video!
I feel expensive Equipmemt has better Q&C so you have a much better chance of getting a well built machine but honestly if you take care of a cheap trimmer it will last a long time as well.
Is it possible to hold the damn thing wrong? Lol cause it's not just me, I have a sthil f175 (or something like that looks like the one in video) and it will not run for me my dad grabs it fires it up runs and cuts. My buddy touches it same thing runs and cuts. I touch the thing and it shuts off. I've been "trained" on how to use it. it's pretty well common sense. Done with the fucking thing piece of shit haha
He started it this morning, he cut the length of my deck, then handed it to me. It dies. Has gas has oil, all new, new spark plug new air filter. 2and year in a row I'm battling with this thing. Haha done with it I'll just buy a new one!
They are like a Diesel engine they can take a heck of a beating over years before dying. (They casually worker doesn’t know much except get off truck mow and on to the next yard.)
Did you turn out the low speed screw on the carburetor? Sometimes they have to be adjusted. It's also possible the idle screw is turned out too far and it's bogging down due to lack of fuel. Taking the carb apart and cleaning the insides with carb cleaner also helps.
I have a Stihl FS36 Curved shaft Trimmer that I purchased in 1996> I always performed maintenance on it. This season it started and ran fine . But after the first run it became hard to start. I Changed out fuel lines, filter and primer bulb. Checked spark aresstor which was fine. Checked compression which was 75 psi. Cleaned and rebuilt Walbro carb WT160B using Walbro Kit K20-WAT. Still hard to start but when it does run it it works well until you try to get it to idle. Any suggestions? What is the relationship between the L Screw and the Idle speed adjustment?
yes, your low compression is no helping the engine run like its supposed to. as for the L screw and idle, when you add fuel, it will lower your engine speed, so you need to adjust the idle screw to compensate.
Sorry if this is somewhere below - what would cause the air filter to be soaked in fuel? I bought an old fs76 and fuel drips past the orange choke semi circle if the strimmer is turned upside down? Any suggestions appreciated, thanks
sure, then carb is leaking fuel. either the pumping diaphragm isn't sealing like it should or the metering diaphragm isn't returning to position like it should. The best option is to just replace the carb.
They MUST be built better. Have you SEEN the way manual labor treats equipment? You said yourself that the previous owner kept it outside. Most likely some guy filled it from the wrong gas can.
In answer to your question, I'm guessing these machines last longer only due to superior build quality. After working on a couple older Poulan chainsaws with most Torx fittings at T25 I was pleasantly impressed to find that an FS110R had T27 fittings to do the same jobs as well as being more consistent throughout the machine. I had the above FS110R given to me in abandoned condition with some obvious issues visible externally. My research lead me to this video because I want to learn all I can about this type and make of machine before digging into it. I didn't read through all the comments here so I don't know if anyone mentioned these things, but I'm wondering whether your machine is NOT actually a total loss. Low compression reading aside for the moment, the air filter might be clogged internally and still not obvious on the outside, although that one did look pretty dirty to me. I just bought my first-ever ultrasonic cleaner and one of the first tests I want to do is run this similar type of air filter through it to determine how effective the recommended cleaning methods really are. I already used brake clean and air to get most of the debris and oil out of it and then washed it in warm soapy water, rinsed and dried well, so my test will hopefully yield some definitive results. Next thing I noticed (which seemed pretty obvious to me) was the excess carbon buildup in the exhaust port. Between the intake and exhaust being clogged I question whether this machine might have kept running if they were thoroughly cleaned. Then there's the issues several people have mentioned - I would have removed, disassembled, cleaned and inspected the carb to confirm that it wasn't a carb issue like a pump or metering diaphragm, needle seat or filter screen that prevented it from continuing to run. Frozen piston rings are another thing that really seems to point to low compression, shiny or dull appearance notwithstanding. Since it had such good build quality I definitely would have put time into trying to give it a second chance at life. I would have pulled the head and pulled the drive shaft to inspect that as well as rotating it to confirm clutch, etc. condition at the other end.
Throw it away and go get a Husqvarna 525. Every pro gardener I know is switching to Husqvarna. Especially the backpacks. And that includes every big time gardener I know.
And this is why we make sure to put the 2 cycle gas in our 2 cycle engines And make sure to get the ratios right. We know not to put regular gasoline in a 2 cycle because of the damage it can cause however some of us don't always read the warning labels And or ignore what we are told We can even forget sometimes And that's why things like this happen.
I like my Husqvarna. Believe it it not. I use a 128ldx with an old craftsman pancake head attachment. It's so well balanced that I kinda get angry if I have to use another half shaft.
I feel like it's a mix of good parts and better care. But eventually they do die off. An old fs90r that i had as a parts weedeater was so worn out you could spin the engine over with your hand effortlessly.
I think all of the things mentioned contribute to the life of any machine. However, the most important is machine abuse and there are many way to do that...Take care of what you got and it will take care of you !!!
I do believe people take care of more expensive equipment and wont spent that kind of money if they didnt. All you have to do is work on a Stihl and you can see the difference between it and a 99 dollar model .
Hey I gotta question when I went to the shop to get my throttle tigger fixed they also find that my carburetor is boggling down so do that mean I need a new carburetor?
I have the fs 55 I’m getting around 20mins of use then it won’t start back up ( had it for 4 years) and maintain around 20 gardens, it’s had a carb clean new gasket & diaphragm has compression , new file filter & lines and a new tank , spark changed , flywheel cleaned & coil any suggestions guys ??
@@paulstir mine just started doing the exact same thing. Runs like a champ for about 20 minutes, then it will come down to idle and die. No restart. Acts to me like someone threw the kill switch. Won't even think about restarting. No clue.
@@INSIDEHOUSEGARAGE yeah, maybe there's a small amount of nickel and carbon fused in the entire cast or just a small coated portion of it on the displacement wall of the combustion chamber... idk that just my guess. I would like to know why the price as well lol
If you didn't already get the recoil off then remove the orange top cover, remove the other 2 boots on the recoil then remove it from the engine. Next them the screw in the middle of the white part where the rope goes. Then lift out the white part and you'll see the broken recoil spring. After that I can't help as you'll need to keep the spring wound .
Mix oil 40:1 for everything. If you follow instructions on 2-cycle equipment from different manufacturers you need 32:1 up to 50:1 Mix everything 40:1 and you'll be good
You forgot to adjust the three screws on the Carby. LA (idle speed) L (low mixture) and H (high mixture). This is often a problem as I found on mine. They can end up being "out" after much usage of the machine and need to be re adjusted. There are videos out there showing how to do this.
I think you're talking about making adjustments to compensate for issues with the carb or the engine? If so, you can try but you can only adjust so much to make up for s diaphragm that's beginning to harden up.
Purchased stihl fs 56 rc 5 months ago. Use it twice a week. Have had 1 day where machine didn't cut-out on me. Most times it will happen 10 times in a 20 minute period. I don't run it at full throttle very often but it will cut-out at any speed, even full throttle. When moving from 1 area to another and you release the trigger, it dies, not all the time but sometime. Engine can be cold or hot. Had it back to dealer 3 times and of course, it doesn't happen there. Using regular gas and stihl oil. Any suggestions as to problem or solution.
typically when it dies during usage its running out of fuel. i would suggest turning the L screw about a quarter turn counterclockwise and turning the idle screw clockwise about half a turn to it doesn't die from the introduction of more fuel.
I just bought the same machine .it was parked up for 5 years .it starts and runs well .but when I stop it and try to start it again it won't start until it cools down. There is also a hole in the bubble squeezer.
@@liammulligan1279 I have videos where I tune the trimmers I get working, However, I don't have a video discussing the general tuning basics as each piece of equipment is unique.
I have a huqvarna weedeater,I put a new carb,gas lines,fuel filter and spark plug in it,it will only run about 30 seconds and quit,Its adjusted and will run but quit,help please
I would remove the spark arrestor screen and inspect it. If that was Okay I would try to adjust the carb and if that didn't work, I would replace the carb.
If you like doing that sort of thing, it's kinda fun to do anyway. An expensive engine (such as a Stihl, Husky or other high-priced make) is worthwhile pulling apart because if the piston & cylinder are trashed, it's possible to get aftermarket cylinders and pistons which are cheaper than originals and often perfectly good enough for home use. If you use the engine for a living, it might be worthwhile getting factory original repair parts, but the cheaper stuff on Ebay or Aliexpress might be fine for lighter use. After you're done replacing the junked piston/cylinder, crankshaft seals etc. make sure you put oil in the gas!!!
