Steve is a life saver when it comes to small engine repair and adjustment! He has helped me out in sooo many ways! His knowledge regarding beer is almost as good! I would like to offer one CAUTION though. DO NOT buy$$ anything from TEESPRING!! There T-Shirts are the worst quality, their silkscreening work is horrendous and their customer service is NON-EXISTENT! They will not respond, nor do they offer phone numbers that will get you through to them!!

Not only can I get some badly needed yard work done, but you saved me about $200 and a lot of time waiting for our local saw shop to get the job done. I spent a whole $18 for the rebuild. That's it.

If your model has tuning screws with a special head designed to prevent you from tuning them with normal tools, you can buy the special screw driver. Or you can take a dremel with a cutoff wheel and grind a slot into it for a flathead screw driver. My carb isn't quite as pretty now (I had to cut through some extra material around the screws too), but it got me tuned up without having to wait to get the tools! Wonderful video.

I cleaned the air filter and made sure the line was out. I did exactly what you said to do. The high speed was already pretty good, but I found the sweet spot on the low adjustment, and the thing screams when I pull the trigger now! And it only took me about half a beer to do it.

Steve ,I just watched your video on how to tune in my fs38 stihl line trimmer ,I did what you said,my trimmer works perfect now,I only bought it three weeks ago and when using it,either you had to hold the throttle all the way down and then it was too fast,but now I can control how fast I want it to go,thanks Steve for the information,it only took me five minutes to do that,and now I have the perfect trimmer,thanks again.

Hi Steve, from down under in Australia. I have just watched two of your videos and must say that I was very impressed with your laid back but informative and educational approach. I have just bought a carby kit for my Stihl SH55 blower and planned on fitting it tomorrow. The problem being that it starts but wont rev, but after watching one of your videos, I am going to remove the spark arrestor first to see if that makes any difference. But don't worry as I realise the safety issue of not having one, so will purchase a new one if this turns out to be the problem. I currently have three pieces of Stihl equipment and overall have been pretty happy with all of their products. I have saved you in my bookmarks so that I can easily access your help videos in the future should I need any help. I'm glad you were enjoying a Carona in one of the videos as I enjoy the beer, but am currently sipping on a Hahn Super Dry.

Awesome mate! So happy I helped....

Steve's video is incredibly detailed and produced so that even I can be successful getting my weed eater to run great!

I just changed the carburetor on my STIHL FS55R and watched your video and it runs like a champ ! Thanks so much Sir. I'll drink a beer and toast you !

Thanks for the video Steve, couldn't have got my Partner 330 going without it. Had to wait a couple weeks for new gaskets to come from the States so took a few more beers longer!

If after using this tutorial you're still having trouble with engine RPMs and/or stalling, please check if your trimmer carburetor has a clutch adjustment screw. My trimmer is an old Stihl FS36. Besides the high and low speed screws it has a clutch adjustment screw located below the two screws. It's slightly bigger then the others. If you unscrew it way out then on low RPMs the head will spin very fast. You need to screw it in enough so that the head stops spinning but the engine doesn't stall. If you screw the clutch screw too far in while the engine idles, the trimmer will turn off. I suggest to unscrew it half a turn, start up the trimmer, let it idle then very slowly turn the clutch screw in untill the engine stops. Make note of this position, unscrew it one quarter and now the engine should idle perfectly, and the head should not spin. If it does, you need to fiddle with this screw a little more. Eventually, you will get it. Naturally, the location and type of clutch screw may vary per model. Please see the manufacturers manual for reference. Also, I found that when adjusting the low speed screw a certain amount of turns, it is best to do the same amount of turns with the clutch screw, with the reference point being the lightly seated position as Steve describes it. The manual advised this but does not specify the amount, so sticking to a 1:1 ratio is a good starting point. Other than that, thanks for the video Steve!

Clutch adjustment screw? Hilarious!!!

I must say this was an excellent tutorial on how to tune the carb. I just installed a new one on my FS 90R and was very helpful. Right to the point and good video. Mine was a one beer job. I was thirsty. what can I say.

[@StevesSmallEngineSaloon]

Right on Bob! Thank You...

Steve, thanks for providing these videos. The lessons you have provided on KZbin helped me to rebuild my Weedeater Carb, it took me awhile but I Got it Running. I ran out of daylight, so fine tuning will take another day again thanks. Ken

[@StevesSmallEngineSaloon]

Great to hear!

[@OrlandoCRamos]

Thank you for making this video. Actually Thank you for making all your videos. I have been watching your videos because I would like to learn how to keep my equipment running. Today this video helped me. My fs55 wouldn’t stay on and a quick adjustment of the idle and I was back in business. Thank you.

Thanks Steve! you saved my Stihl fs38. It was crap until I pulled those caps and followed this video.

Purring like a kitten 😺 roaring like a lion 🦁 in 5 minutes or less. Thank you! My primer bulb had been going bad and boy did that make it hard to keep running! Installed a new one and runs great now after ur guidance.

Hey Steve just tried your fix to repair cracked gas tank on a Stihl FS36. Did like you said and used a soldering iron- PERFECT FIX!! Thank you

WOW! Thank You...

[@alexfher00]

Thanks a million Steve. All I knew was turn both screws in then back out 1 1/2 turns. Then just tweek both of them until weed eater seems to be working OK but had no idea just what exactly I was doing and why. You've saved me from so many frustrating afternoons when I couldn't get it to work Now there is a "reason to this madness" Next beer is on me, Bud.

Perfect! I had a Stihl trimmer not wanting to stay running. I cleaned the spark arrestor which helped, but did not resolve the issue entirely. So I ordered a new carb, and your video was excellent on how to adjust it. My FS46 Stihl is humming once again. Thanks for your instructional video.

[@StevesSmallEngineSaloon]

Nice work!
