I have to fit a new cylinder liner to a Comet.The mechanics of the job are not a problem, how much clearance is too much between the liner and crankcase mouth before there are oil supply problems to the piston skirt.
Is there a 'perfect' measurement for the oil hole in the liner and if not how close to the bottom of the crankcase mouth is it sensible to position the oil hole in the liner..John
