You go to jacking the compression on that thing you'd better have the arms of a gorilla .That's one of the hardest pulling SOB's ever made .

I have a big stock Sachs 143 thats more of a bear to pull over than the 2100 with jacked up compression. I have a D handle on the 143 and you can not drop start it..... the foot in the rear handle is a must.

I've heard the 298 is worse - and that adds up, as long as it has the original smaller diameter starter.

I know one of my 166 had just 190psi stock piston and used to kick my butt even with a decomp. The hard plastic T handle snapped in to one time on a start on a kick back, stung my hand big time. I thought oh heck no never again. Stihl 460 rescue handle went on that saw from there on.

I took the cylinder off this morning. Squish @.050 as a member stated his was. What I thought was scratches ended up being barn find grime and carbon streaks. The saw was stored for a long time without a muffler. I'm going to try a 395 piston. I can always go back to the original. I was surprised how large the chamber is dished on this cylinder.

So do you guys think there is anything to be gained by the window design of the 395 piston compared the the stock thick ring 2100 piston windows?

I think the 395 is slightly taller only a mil or two from what I can remember.

I lucked out and picked this NOS thin ring piston and rings up off ebay a few weeks ago.




Other way round, I'm sure the full skirt 2100 piston is higher than a 395, I have both on the shelf, I could measure.
