So the purpose is to lock the engine when trying to unscrew the starter cup or flywheel nuts. - OK, I can see that, but I would be a little apprehensive to use a tool like that for that purpose. Don't want to mess up my piston. Thanks for the info

Does anybody know what tool 4282 890 2700 is used for?

Compression release problem solved. I carefully double checked the valve lash again and it was a little too lose. I guess it doesn't take much

OK, thanks.

Here is what I have done so far. Installed new cam gear and made sure timing is dead on according to manual. Compression release nipple on cam is moving freely in and out when pushed manually. Valve lash is 0.10 mm (using Stihl gauge and adjusted and checked when engine is cold). Engine starts...

Either everybody has gone on vacation or nobody knows anything about Stihl engines and I thought this was the Stihl forum - very disappointing to say the least. But maybe somebody can answer this. Does a 4 mix engine fire at every revolution? I am also just curious about that too.

My FS111R is all back together and runs like it was brand new. I couldn't be more pleased. Since this is practically a new engine is there a break in procedure that I need to follow or can I start trimming away like nothing ever happened? Btw StarTech, you never explained what you meant by this...

....like how? And if you are talking about me I don't have a contract with anybody

Update! I haven't heard from Stihl and I don't expect to. That's fine. In the meantime part number 4180 020 1209 arrived last Friday and yesterday I started putting everything back together. By the way I got a great deal on this part from a Stihl dealer in Texas ($95 + shipping) for a brand new...

This is the complaint that I filed with Stihl USA and a case number was assigned to it: I am the owner of a FS111R trimmer, which failed even though I only use Stihl oil since the trimmer was new. According to my local Stihl dealer who did a leak down test, the problem was with the valve train...

RevB you are right. Theoretically none of this is easily done, but there is always the genius who comes up with a way to make this an easy job. As a matter of fact, while I was messing around with the cylinder, one of the valve seats actually fell out of the block. That's how I know what the...

I was afraid of that. I don't see the seats in the parts list. Just for the hell of it I will call Wilson-Dismukes (Stihl headquarters who happen to be in town) and talk to one of the techs. I know they probably can easily replace the seats if they wanted to. Otherwise I will give it a shot...

I got the engine apart and it looks like the Stihl tech was right. looks like a valve job will make things well again. The cylinder walls don't have a scratch on it and the piston and rings definitely look good. Also the decompress nipple on the cam is good but I may replace the cam anyway even...

Thanks StarTech. I couldn't have asked for a better explanation. Before I tear into that engine I will check and make sure that the decompression nipple moves freely and is not stuck

Thanks StarTech for the decompression info. How does it work on that engine?
