Looking for wisdom or even wild ideas.
In reaching the end of my repair/rebuild, I adjusted my valves to 0.008 and 0.010, then ran a compression test. Both cylinders ran up to over 150 PSI on about four kicks. This seemed pretty good, being about the same or better than I was getting before the start of repairs last year. With everything back together I was feeling cocky and guessed it might start on first kick. Very wrong. After about 12 kicks there was obvious difference in how much compression I was getting. Tested again and both cylinder were around 75 PSI or less. Gave one cylinder an oil squirt to test the rings and no change.
So, I'm looking for ideas, opinions, guesses and, even, sage advice as to what is going on here. A few added bits of info: new head gasket, well annealed and coated in copper sealant; in the rebuild, honed bores to a looser fit (0.004"), because my pistons showed scoring; reused my old rings because they showed no signs of wear, even though the pistons were scored (I could see this as an arguable cause of the problem if I hadn't, one hour previous, had god compression); valve train seemed to be working fine with TDC found with dial indicator.
How about: Blew a leak in the head gasket between cylinders? Snapped the cam shaft? (Easy enough to check if I want to pull off one of the valve adjuster covers just put on.) What do you think? No wild guesses will be sniffed at. No offense will be taken if your suggestion starts with, "Richard, you dumb..."
Edit to the list: maybe i fell asleep when installing the idler gear and missed a tooth?
Thanks
