I did a compression test on my recently rebuilt 260z engine. It has about 1500 miles on it. On the dry test with the carb fully open and the coil wire off I get the following results # 1 thru #5 came in at about 72 lbs but the # 6 came it at around 90lbs On the wet test all came in at 90 lbs including the # 6. I am rather new to this and this is the first time I have done a compression test, so my questions are- why would the # 6 not change from a dry to wet test. The warranty expires next week on this engine and I wanted to do this test prior to the warranty expiring.Is this something to be concerned about? Thnaks zdude1967
