Hi all
Stumpy advised me to post this in order to decide what to use when I reassemble the top of the engine : the muff height is 3.059 inches; the piston has 9010 on it and
Conway Motors say that's 9:1 compression; the previous master-engineer has fitted 1 x 1.63mm, 1x.93mm aluminium plates and 2 x 0.17mm paper gaskets which, by my reckoning, reduces 9:1 to about elastic-band strength. What does anyone feel is the correct shim/gasket combination to aim for, please, to get the compression down to about 8:1 and prevent my beating the big end to death in the first couple of miles?
Regards
Phil
