You can measure the squish using some lead solder into the spark plug hole. Usually you do not want to go less than .015" on a work saw. But you measure the solder once you have squished it by running the piston into it. Then you can adjust the cylinder from there.
On the piston skirt, you can cut the skirt on the intake side only. By cutting a good chunk out of that you will make the saw run better. Not sure why, but it works.
Of course you need to match the muffler to the worked over exhaust port and dual port the saw as well.
If anyone wants to talk to smarter people than me, send me an email.
Scott. | I tried doing only the intake side but it seems the piston becomes unstable and rocks? by taking material off both sides seems to stay balanced and works better(for me anyways.)
