Compression Release on FS111R not working

[ueww40]

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 immediately (on 2nd pull) and runs perfect under normal operation. The only other thing is that I feel it is running a little too hot. It just feels that way when I put my hand on top of the head. And i know if I were to remove the plastic cover and put my hand on the valve cover I would burn myself pretty good. Is that normal? I must add, the engine is brand new and has about 5 hours on it so far and I am still breaking her in (with other words taking it easy when trimming with stops in between every hour or so). As always your thoughts are appreciated.

Trimmers get hot. I wear a sock cut down, on my arm, so I don’t get burned.

OK, thanks.

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

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

Threaded Stihl piston stop for 10mm spark plug hole

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

It is a piston stop used when the engine has to have a flywheel nut loosened or retorqued.

A piston stop will not screw up the piston. I use one all the time. What will screw up the piston is forgetting the stop is in the spark plug hole, and then cranking the engine.
