Yes I agree, guess I'm Getting Old. 2 to 3ooo RPM Will get the oil to the cam lobes( my bad ).And to Jonathan Sacks.You are apparently using some sort of engine Analyzer.When the spark jumps the gap it bleeds off from a peek to zero .There is A spike in this curve when combustion takes place ( known as the combustion hook ) Compression can be estimated from where this event occurs .What the Analyzer is telling you is that the spark is occurring at the wrong time ( I think) So you eater have some wires crossed or You are getting cross fire between two high tension leads.And did you hear about the railroad inspector that was ringing wheels whit a hammer.Seames he replaced 2 hundred wheels before he discovered his hammer was cracked.Good Luck Jim --- --- macthehammer@xxxx --- EarthLink: It's your Internet.
