I posted earlier about a 1984 mustang GT that was randomly stalling out and occasionally backfiring through the carb. It has a Holley 4160 4 brl carb. We tested it for vaccum leaks and there doesn't appear to be any, and adjusting the timing has had no effect. A custom engine builder in Lakeland said that the secondary diaphragm spring in the carb may be worn, causing the barrels to open up prematurely/randomly, flooding the engine.
One thing I noticed today, that I didn't catch earlier is a mysterious orange piece of rubber, that almost looks like a part of a Holley umbrella check valve that goes near the accellerator pump, except it has a perfect little hole where the stem should be. I found it in my air cleaner. Anybody know what this thing is.
