When I wiggle the freewheel on my fs90r when at TDC the valves still move slightly. When I wiggle the freewheel when not at TDC the valves move much more. I have two fs90r and only one of them has the valves slightly move still when the freewheel is wiggled at TDC. What's up with that? New to the channel great stuff thanks.
That's the best explanation on how to find top dead center on the power stroke I have ever seen.

Thanks Steve. Super simple and to the point! I actually bought a couple of Stihl products with these engines and if I had known they had valves would have stuck with anything else 2 stroke.
A year of standing on my fs130 to start it because it pulled so hard, did this and it works perfectly again! These videos are awesome!

Great info. I'll be tuning my FS 90r valves for the first time this week based on the vid. Side note, I just picked up a FS 90r at a thrift store for $20 (deal of the century) and gave it to a friend. It needed $25 in parts (mostly cosmetic) and works great. Literally started on the third pull when I brought it home. I'm forwarding this video/your channel to him.

thanks Steve....Sleemans late 80"s many a trip to the Guelph outlet on a sunday when they were the only ones open for hundreds of miles around
My main problem was pulling out the cord, I took it back to the dealer he said that's normal. I bought the kit after watching a few videos. Now it pulls fine and runs better
Thanks Steve! Great information. Had just watched something similar before I found this. Now I have hope for humanity. Also, glad to learn about the 4-storke part. I have a 4-stroke Shindaiwa which uses a mix. Not everyone believes me.
Hi Steve. This is the best video that I have seen on KZread! You do an amazing job of describing the process of setting up the valves with the feeler gauge. I could not find any of those feeler gauges in this town! Thanks for showing us how to use a regular gauge by cutting a sliver off of the end of the gauge. No other individual explained that we could use the .004 inches which is .10mm gauge! I appreciate that you're so thorough! I thank you so very much!

As they say in South Boston, “wicked pissa”! My Fs-90 was hard starting, not running well and stalling. Replaced the air filter, the fuel filter and adjusted the valves with the Stihl kit, and it’s now like a new machine. Thanks!!!! Much more detailed solution than other videos.

Thanks a lot Steve on showing how to check and adjust these 4 mixes properly. Seen a couple other vids on here on doing this, but none have mentions the step about making sure you have it set on the right stroke before you start checking clearance and doing any adjusting. I think those other vids left that part out. Important step to not mention! So make sure guys when your adjusting you do this. If u wonder hey I just adjusted mine and still don’t seem quite. Could be it wasn’t on the right stroke before u started. Anyways thanks again Steve. I now know and feel comfortable enough to do this myself and not take it to dealer and drop it off just to be checked and if needed adjusted when I can do it myself in like 10min or so.

Hey Steve! I got a good one for you. I drank a 16 oz can of beer and cut a 0.10 mm feeler gauge from the empty. I mic’d it and it was perfect. Thanks for the videos.
Great video though... Glad to see someone else cares about good content and recognizes that good content equals a great resource for those who seek to find it. Keep up the good work... I'm actually working on some videos myself and still learning how to direct myself...

Picked one of these babies up from a neighborhood garbage pick. No fuel was going into primer bulb. I was prepping the carburetor for a rebuild before taking it off machine. Sprayed with carburetor cleaner to remove all the crud and shot it with compressed air and now it runs awesome. Guess the rebuild will have to wait another day. Going to hit the valve adjustment next as routine maintenance. Thanks Steve for your expertise.

Hi Steve: Thanks ever so much for all the great info you are putting out there. Unlike some other people who who try to inform us about the mechanics of how things are suppose to operate, you are always very precise, clear, and to the point with your instructions. Your instructions, we can understand. I have a Stihl trimmer KM 110 R. Piston & cyl are bad. Can I get a KM 131 R piston kit instead of a KM 110R ???
This video really helped me out. I was going to try and set the valves for the first time on my Stihl da 90 r and your video came up. Great job as always explaining in detail how to fix my machines. Thanks again

Just bough a Stihl FS 131. Before my purchase I did some research and saw that the valves needed to be adjusted time to time. Well after watching your video, I realized how easy it was and feel I made the right choice. Plus your accent reminds me of my mother's side of the family with their Finish accents they had. lol. Love the way you show your views how to do things without making them sound like it's rebuilding a rocket ship. lol

Just saw this. Now I can do the valves on my FS131 when the time comes. My Shindaiwa blower probably needs it since it's been 6 years. I'll check to see if you have a video for that. Thanks Steve, great job.
Like he said in the video, you can adjust these valves by hand, no feeler gauge necessary. The amount of slop on these valves after running a few hundred hours is very noticeable. Just adjusting the slop out is plenty good enough for routine maintenance.
Just discovered your channel - brilliant - concisely and accurately explained. Many thanks from the U.K.!!

Your vids are always supremely excellent. All info, no fluff. Btw it’s worth using a caliper or mic to double check the actual thickness of your feeler gauge. The trick of 1/8th turn is one I’ll use. My ht131 is running crappy so I reset the valve clearance this am. Think I set to the wrong stroke since it down on power and backfiring under load. Thanks

I'm commercial I have a Km 110 and a Km 111 I bought the 111 cause I was told my stuff wouldn't be ready for a week to 10 days (valve adjustment and new plug) and can't afford to be down that long cost $45.00 + tax for valve job. After watching your video I went to the same dealer to purchase the feeler which was out of stock they don't usually stock it special order so I went to ebay. After adjusting my valves I understand why he does not stock the feller gauge. BTW Ballentine Ale is the perfect beer for the job.

Hi Steve. I have three of these machines. Two FS 90 R and one FS 110 R. The one 90 I took to a stihl dealer. They said the governor was out. It will start. But will not rev. The other two runs well. About an hour they will die down. Let off the gas and go again for about twenty minutes then it will do it again. The 110 has Black suit on the muffler.

My fs130 was running great, easy to start,huge torque but i decided to have a look at the valve clearances anyway (number one rule, dont fix it if it aint broken). i was surprised to find the rockers very sloppy. adjusted as per this video TDC, no movement in rockers when moving flywheel. feeler slight resistance at .10mm, first thing i noticed was the machine was hard to start, then after some run time i realized that it had no bottom end torque at all. let cool down, turned each rocker bolt anti-clockwise between 1/8 and 1/4 ...about 3/16 turn i suppose, then tested machine and it was back to normal again.
Great video Steve ...thank you!
