Hi Dick,
I'm going to buy a cylinder bore gauge and measure the bore at the
bottom, just above the piston (I don't want to remove the piston) and then
measure the top. I will then check to top of the piston to see if it's 0.020
over , which I think it is, the cylinder should measure out at 2.96" if not
I have a problem. How's this sound?
