1. Does the car idle well?
2. What is your GAV setting when driving?

If you gas cap was not venting it will have trouble running anytime. Drive it around with it off and see what it does. Try opening the GAV another quarter turn and see what that does to your stalling.

Removing the secondary well is not the solution.



Hey terrific reply Tin Cup!! I do notice that when I brake and come to a stop, it does seem like the idle surges as if it just got gas. In fact, when I start to stop, I can sort of tap the brakes to slow down and the idle seems to respond to that, ie surging effect.


But I really don't see what the secondary well does for the carb. It seems to me its just a smaller tube inside a larger tube.
I'll play with the float level, great suggestion thanks!!
