Stihl FS 55RC trimmer won't start fix

[@freeflight4ever]

A handy tool to have for testing these carbs is an air pump with pressure gauge. Connect to the fuel inlet, pump to .5 bar and it should hold pressure. If it doesn't, the cover gaskets are leaking, or the inlet needle is not seating. If it holds pressure, pump the primer bulb till pressure gauge reads 0 and keep pumping till it pulls a vacuum. It should hold a slight vacuum for at least one second. If it doesn't, the primers check valve is defective, and carb should be replaced. If it holds vacuum, connect the air pump to the primers output nipple and pump primer till gauge reads .5 bar. If primer won't build pressure, again its a defective check valve and carb should be replaced. This is known as the 3-step test. The problem with the cheap knock-off carbs is that these motors will often use many different versions of a carb for a given model. In the case of the FS55, I think they used about 12 different versions of that carb, with the carb being changed each time a slight change is made to the motor design. Its best to try to get the right version of the carb for your motor. Theres a black number stamped on the carb that begins with letter S, such as S34, S55, S62, etc., which indicates which version you have. I recommend using the orginal Sthl carb for best results. Great video, by the way. Brian / Stihl tech

I think your approach is spot on. In my experience most people are quick to jettison a carburetor when basic repair would do the job. Your approach is excellent. Btw, you have a good "speaking " voice for videos. No "ahs" or "umms". You're missing your calling. . VOICE over work.

I always put a complete re-build kit in when I have it apart the first time after using my ultra sonic cleaner or flush all passages with carb spray. I had a customer that wanted his riding mower cleaned after I tuned it up and changed the oil, but he did not want to pay the extra hour to do it, so now I always ask if they want to pay for the additional cleaning. Thanks for the great video's.

I would have remove the carb the first time and either put it in my ultrasonic or put it in a small pot with dawn dish soap and boiled it for a while. Then installed a complete repair kit in the carb. Put back on the trimmer only to see it still won't run. Then lay on the ground and kick my feet in a temper tantrum. etc.

I had one that wouldn't prime. I went to my local repair shop and purchased a purge valve for $2, and I was back in business. I was trying hard to keep the original Zama carb.

[@quentinromano8640]

Those trimmers are great. I have a Stihl fs55r trimmer. I had the same problem with the primer bulb, where it didn't prime. This was because my primer bulb base was bad. Its the black plastic part. My local dealer wanted 30 dollars Canadian for just the plastic piece. So i decided to go with a brand new oem carb from stihl. Best part was, it was only 65 Canadian. With the Canadian dollar being so low. It would be like 30 bucks for a new oem carb in america. and it solved all my issues. the trimmer runs like new now.

The STIHL ZAMA carb on mine was made in China also. Maybe the OEM cars are tested, and have better quality control. I find the cheap aftermarket ones to be hit or miss. Allot of defective ones are sent out.

[@TomTom-by5sx]

Like you said, check with the customer about OEM parts then make the appropriate repair. I use mostly off brands for myself and at ten dollars it's cheaper to replace than play with it. I usually check my used supply first as I save them and I will rebuild some for these situations. I also sell them on occasion, if I have enough in stock, this pays for rebuild kits. I haven't had any complaints so far.

Those Stihl trimmers, the FS 38, 45, and 55, spit a lot of oil out of the muffler. I add just the right amount of oil. So when I'm done with the machine there's little spots of oil on the machine. It gets on the pull cord, fuel tank, and even the front cover. It's a pain, and I have to clean it constantly. The stuff on the fuel tank definitely was not from exhaust. That was like spilled gas.

A non priming unit is either fuel blockage, check failure, or vacuum leak. Since it setup a long time, dump fuel into container and try blowing low pressure backwards through the pickup tube to the tank: carb cleaner, dust off, brake clean... as long as it can evaporate/won't leave lines filled. Then ask yourself why you went cheap and re-used a carb gasket in the first place - if that wasn't a problem, it will be [maybe soon].

[@HomeGaragechannel]

thank you Flinch for the tips

[@2008enzed]

Well done video. Given the unmaintained look of the unit, I would have assumed that the carburetor was shot, poor and old fuel having done its damage, and at $10, bought a new carb right away. I am really curious, though, as to what is a “knock-off”. My Stihl trimmer has an OEM carburetor made in China. Would like to know what is the actual difference between Stihl’s made-in-China carb and the made-in-China “knock-offs” beyond what the marketing folks would want us to think.

[@HomeGaragechannel]

I don't really have any ideas either about the difference but all I know is I have a lot of success with cheap carbs so I'll keep using them

[@jackyboi190]

Just brands become over glorified as they earnt their name so people will trust in, plenty of cheap products that are just as good just without the known name!

[@xgamerbih]

If it’s from China it doesn’t mean it’s low quality. Stihl has their carbs made in a chinese factory that actually does good products. You think Stihl would risk that? Now, non-oem made in China tends to be low quality with lack of precision when being made meaning wrong jet sizes etc. but overall it’s ok. ZAMA is a good brand

I would have installed a new OEM carb kit (if available). A lot of newer equipment doesn't sell carb kits any more. Your only choice is a new carb. That is the result of USA environmental standards (i.e. California). I'm not sure if this impacts on Sthil at all but I had a generator that needed a carb kit and this is when I found out this info.

I believe you are absolutely correct. And yes, if it's in your budge always buy an OEM carb. Thank you William Pickering.

Your air compressor is very valuable for cleaning equipment. Blow the crap out of it and you can get most of the dirt off. No prime could also be a line with crack in it. I use aftermarket carburetors all the time. However, I do everything I can to save the original Zama carb.

​@@HomeGaragechannel I finally figured it out! Compression is very good as it take a good effort to pull the starter cord. One think I learned was not to trust a lighted spark tester since a weak spark can indicate it is OK. Took it apart again, regapped the new coil although it appeared fine and still no spark by having the plug out, grounded on the engine fins. Could see a very faint spark at best. Put the new one back in and regapped it and still nothing. Now I had to assume the coil may be OK but why no spark. Came in and watched a few more videos for tips.

Thank you for the comment I appreciate it. Yes it was just a test run. It only ran on the little bit of gas I put in it.

[@manuelmaldonado4951]

what happens if the gas pass the screen with out pushing the roket arm?

[@HomeGaragechannel]

is the spring sill under the rocker arm? if it is then just replace the carb

[@manuelmaldonado4951]

@@HomeGaragechannel yes it is...ok thanks...do you think that is the reason it wont rev up?

[@markmendoza5533]

Have same problem on mine Fs55rc Took mine apart cleaned it up put back worked for little bit took apart again ordered new carb and kill switch

[@HomeGaragechannel]

nice work, hopefully you can get working again.

[@paulfran1]

Can you add a link where to purchase the new carb

[@HomeGaragechannel]

sorry but the link won't last since the listings disappear after time. Just search "fs 55rc carb" on Amazon and you should find it.

[@joreymuse8565]

I need that little diaphragm gasket but I can’t dont the specific one 😓 can you help me?

[@HomeGaragechannel]

To be honest I would just order a cheap replacement carb instead. No shame. Its just easier.

[@joreymuse8565]

Home Garage the whole carb lol or just that gasket?

[@larryrabathaly9503]

What do you use in the spray bottle to clean the engine with please

[@HomeGaragechannel]

it's an orange based cleaner we get from the dollar store but you can find it at any big store.

[@nolinnaik1956]

My carburetor puts fuel in the motor while im priming the lines is that normal

[@HomeGaragechannel]

Is it a grass trimmer? If so no.

[@pyrog.c.c89]

[@HomeGaragechannel]

Thank you Pyro G.C.C for the comment. I appreciate it.

[@timothymek8216]

Thank you for information.

[@HomeGaragechannel]

no problem

[@thatguywiththeford9467]

How much would one of these go for in this type of condition used

[@HomeGaragechannel]

maybe 80-100. thats jut my guess

[@johnwitherspoon7754]

About 110

[@peterkypriotis9484]

Thank you for your video help's a lot. I would have got a NEW cab there cheap as it is than to waste hours resolving the issue. Time cost money today. Great video

[@HomeGaragechannel]

thanks and yes getting a new carb would be a great use of time

[@beingsneaky]

yeah i would have done a better cleaning on the first take apart. take out the high and low screws sprayed those out with carb cleaner. sprayed out every passage on the carb. removed the brass fitting in the carb(slotted screw) blasted that out with carb cleaner. and let it sit for about half hour or so.. BUT if i had an ultrasonic cleaner that would be better. only then if it no work right carb kit or i would replace it. I would suggest that you buy a few of those carbs to have on hand. If you look at the Stihl Carb it is Made in china.

[@HomeGaragechannel]

Thanks for the information I appreciate it

[@Nothing19800]

OK so I replaced the primer bulb in mine mine is dirty I also replaced the filter it’ll run by when I get going it stops. Any ideas

[@HomeGaragechannel]

Sure, the Carb needs to be adjusted or replaced.

[@fredbarnhill9330]

Definitely would bought new carb. Have done it in the past and is much faster and easier

[@HomeGaragechannel]

Yes I agree

[@dominichd3079]

I would close the fueltankcap because most Stihl carbs didnt suck fuel in when priming, they over pressure the tank so the fuel get pushed in the carb. (sorry for bad english i‘m from germany)

[@HomeGaragechannel]

thank you DominicHD
