Conflicting piston clearance info?
On Macs spec page it lists bore as 3.876 and piston as 3.8745. I measured my bore and it was 3.880 and the piston 3.843. that says to me my clearance is .037 pistons appear to be aluminum and only have slight carbon on 1/3 of the piston top. Suggesting it was a recent rebuild before the 30 years of storage.
