A member calls me last night he has a miss on one cyl when running on engines stand one header tube temp is a lot lower than the others. Presses down on the dist cap it goes away. WTF right so I walk him through the normal stuff for a points system, nothing is working. Asked him if he used a metal gasket and is the area it sits on painted. He says so that's what that thing was under the distributor. I put a new paper one there. Have him take it out clean the paint off under the dist and re use the metal gasket he still had. Guess what it went away. Took a hour but it is good for reputation, I guess?
