What RPM during spark test
Hi Malcolm
What RPM was the engine running during your spark test? What type of timing light pickup? Induction or direct connection to spark plug? Running engines in on the test stand I have seen the same apparent intermittent spark using an induction pick up. Seems to smooth out at around 1000 RPM, never have tracked down the actual cause of the intermittent nature of indicated spark. Wonder if it is just slightly lower voltage at idle. Because of the phantom problems with stored vehicles, I try not to get to excited about rough running, hints of missing, etc. generally I wait till I've run through a tank full fresh gas before doing tune-ups etc. Please keep us posted on your mechanical detective efforts. Cheers Phil
