Ok, here's some more info...
I drained the entire tank and added 10 gallons of super unleaded. I also added a can of Seafoam to the tank. I then drove it around for about 20 miles in varying conditions.
The only noticeable issue after 15 miles was a little stumble off 2000 rpms. Sounds a little like vapor lock to me. It's about 80-85 here in Tampa in the shade. I did have an issue last year but added a 1/2 inch phenolic spacer that seemed to clear things up.
Nothing has been changed leaded to this issue.
Dirt in carb? Vapor lock? Mallory dist failing?
