One thing you should do is a squish test. It is just as important to know this or more as anything else on your engine.
Take a couple piece's of solder around 1 to 1.5mm thick and around 1 1/4"long and put your piston about a 1/4" below top dead center.
Put a very little dab of grease on the piston above the wrist pin on both sides of the piston. Lay your solder Tight to the Bore across
the top of the piston on your grease, right above the wrist pin. Now turn the engine over with a Wrench and squish the solder. Do this at least 3 times until you are happy with a repeatable measurment. Squish is measured tight to the bore. If you have us do anything to your engine we will need to know this. If you ship us your engine do not worry about it.
