Hello; I was wondering how much piston skirt to cylinder clearance is too much and if there is too much what will happen? Will the piston rock and catch the edge of the piston in a port causing "Real Catastophic" engine damage? Using a feeler gauge (I know a feeler gauge method is barbaric, but its all i have) I inserted the piston in the Cylinder Upside down while holding the piston with one finger against the intake side of the cylinder (almost in an effort to rock the piston as to generate the greatest possible clearance where I was measuring above the exhaust port) and started inserting blades as large as I could go. Well..... I made it all the way to .005" before the feeler gauge blade was really tight. should I rock the piston when measuring like this or just kinda hold it neutrally like by the piston pin, If I dont rock it in the bore then it is much harder to get even a .003 or .004" blade to slip in. By cocking the piston it seems like I would be better able to determine max clearance, Is this correct? Everyones help on this will be really appreciated.
Thanks, Stuart
