plyroadking Posted May 14, 2013 Report Posted May 14, 2013 About a month after i rebuilt the engine in the '40 it started idling rough, I knew it was a vacuum leak as pulling the choke smoothed it out. A week ago i was trying the brake clean vacuum leak test and discovered that the throttle shaft was very worn and air was being pulled in around it. I dug through my spare carburetor collection and discovered all of them were loose except for one with a steel shaft as opposed to the brass shafts. I switched it out and now the car idles great. Has anyone else encountered this? Is there a way to sleeve the carburetor base? Or are we stuck looking through collections to find less worn shafts? Quote
Young Ed Posted May 14, 2013 Report Posted May 14, 2013 I believe the common solution is to drill the carb for a bushing. I haven't tried it but I have some carbs that are getting there..... Quote
