Re: Hi all! Help with Goodyear 5hp 1954 (3564)

Sorry, I somehow missed the inline part. I have both kinds. I tend to use the inline type only to diagnose a bad cylinder if I have a miss that I’m having trouble tracking down. If I’m working on an engine doing tune up work, I use an open air tester to check for spark. I guess I’m so used to my own methods, I just missed that part. That doesn’t mean my methods are the best, just what works for me.

I have had neon inline testers show a dull light when the plug isn’t firing enough to light the charge in the cylinder. It is much more obvious when running two inline testers at once with the other plug firing properly to see the difference in intensity.

Frank is spot on about the points. They are usually the culprit.
