Chainsaw Repair

Here is a picture of the cylinder after I lowered the bearing area and then sanded the bottom of the cylinder.
I started with .035" and when I finished with it and put it in the case the squish is now at .019".

I also widened up the intake and exhaust ports and cleaned up the transfers a little.   None of it was big steps just a little grinding to open it up a little.

In the second photo you can see where I put the covers for the transfer ports back in.   They had to be ground down a little to because the bearing seal rides on them also.
