On my dual weber 44 idf's, I am having fuel dripping out of one of the accelerator pump jets when the car is off. I assume, it is also when the car is running. There is a fairly large amount. It is pretty obvious that it is from the pump jet. I really dont think it is a float height issue cause it is only one jet that is doing this.
The car has been sitting for two weeks due to some electrical issues. The engine was running fine prior to this. Now it is running ok however I am now having a popping noise when I decelerate. It may be present at other times however the car is so loud that I cannot hear it. Ideas? |

so do you mean it's dripping inside the carb from the accelerator jet nozzle, when you shut if off?? Or is it leaking from the accelerator pump cover on the outside??
If inside, I'm thinking fuel percolation in the float bowl. . look for a link to drilling pressure relief passages in the top plates |
