Re: 8BA compression issues
The crank gear issue is still an unknown. I did speak with the engine builder who assures me that the marks on the cam and crank were aligned. I have had a limited amount of time to work on the problem and garage temperatures near 100 haven't been conducive to my productivity.
Re: the valve clearance, in view of the fact that all of the cylinder compression readings are 40 ((except one at 20) I just wonder whether a small error in the valve clearance might prevent complete closing. Obviously, the one outlier is likely stuck as well.
