I have an Autolite 1101 on a 1969 250 Mustang, automatic
I have been tracking down a vacuum leak and the cigar test revealed smoke emitting from around the lever pump. sure enough. The entire throttle plate shimmies back and forth in the carb housing. I replaced the lever pump, but I'm sure of the best way to stop the leak, which is around the throttle shaft. It wiggles less than 1/16" but that can make a big difference, apparently...
I fashioned some c-clamps out of thin washers and added them to the small gap between the lever pump and wall of the carb. There was a noticeable improvement on performance, but it's still not air tight and I don't know how long those washers will last.
Has anyone come across this problem before? Is there something missing?
