I got a 55 husky practice saw. Practice as in, trying get a little bit more out of a bunch
of junk. Split the case and installed new bearing and seals and bolted the chinese cyl on it and measured the squish, .055 no gasket Not the worse china cyl I have measured, but bad enough. This will be my first attempt to cut the base on a cyl, which is why I am using cheap china parts. Just looking for a good target number, thinking .020, but is that cutting to much for a 53cc saw. I plan on trying a little porting once I get the squish where it needs to be. The ports on that china cyl look a lot smaller than a oem so even a little bit of grinding should help.
