I actually got the engine in and car running, the linkage was a pain.
The Offset was a problem as well as the linkage running into the air filter bases.
I have it set up fairly well, the left side only opens a split second before the right- can't find a solution without having a perfectly straight drop link from the carb to the arm on the right side- no amount of adjusting equalizes it exactly.
Dammit.
Maybe different air filter setup.
