Carburetor help needed
Holley model 4150.
At idle, there is fuel dripping off the secondary venturies. So much fuel that the car floods and will not stay idling. You can actually see 2 to 3 drips per second dripping off each secondary venturi. What is the problem?
Thanks for your help,
Steve

Has anything changed/occurred prior to this condition appearing?
Have you checked the float on the secondary bowl? Not knowing anything else, I would start there. pull the sight plug. If gas pours out, that is your problem. If that is the case, it could be the needle/seat gave out, fuel pressure increased too much, dirt lodged in seat, etc.
Good luck.
