Hey Ron, good to hear from you. I feared that your answer is the likely cause. The coil wire is fine, so it's the distributor. With the Webers the distributor is next to impossible to access. I can't even see the clips, every thing has to be done blind unless I pull off the two front Webers. Can you see the distributor in the attached? See what I mean. Spring is almost here, why now?
Thank you,
Tom
