Cut it!

What all did you do? 

I aint cutting nothing here as I only get $50 or close for them. One of those saws I get backwards in real quick. 
I like them though as I have owned them myself in past. coil spring anti vibe and 42cc great deal on the cheap.

Now in the  chainsaw weight threads I was surprised what it weighed. Thought it would be little less.

The cylinder has been cut and the bearing pockets ground out to reduce the squish to about 0.021".  The intake and exhaust are at about 60% of the bore, and the timing is quite changed.  This one was an experiment to see if the later cylinders that came with the cat converter equipped saws could be made to perform.  The have considerably bigger combustion chambers and less compression.  It goes pretty well, but not as well as an early cylinder does.
