Joe are you in that area where stihl used 1mm base gaskets instead of the .5mm gasket like we use here?
Nope. We get our saws with the .5mm gaskets too.
The current issue is with a saw that is currently under trial ;).

You won't change the port timing that much by lowering the cylinder .The degrees will remain the same as far as "blow down " between the opening of the exhaust and opening of the transfers .The intake will advance slightly and the exhaust will be retarded slightly .Probabley around three degrees which if anything will increase the torque but might slightly decrease the top end speed .

I had just completed the job and like Al said, the torque seems to have increased, and the top end has reduced.
Not a bad thing because the crank big end rollers will last longer.
The best part is that the fuel is burning cleanly now.

Joe
