Like Mom said it jumps, you will never get continuity that way unless something is bent. Have a picture of both rotors, distrib and cap so I can help you out? The up and down play is normal up to .040 I believe.
Well...that answers it totally...many thx.
I never knew we had an "air gap" and continuity was made by "a spark" between rotor tip and each s/p tab (port) inside the cap. Up/down shaft movement is natural and up to allowed tolerance. Thx for clarifying.
Doesn't air-gap "spark" destroy the s/p tabs inside the cap? Longevity of cap and rotor ultimately suffers. I guess that's why we replace both at ea tune-up. Ultimately I will install electronic ign and all this goes away.
A-Body forum is the best!!!!
