Q: Accelerator pump not sealing

asked by on October 24, 2016

Hi,my accelerator pump is not sealing properly.There is always a bit of fuel at the top of the pump plunger where the rubber boot is.As a result,my fuel bowl level drops from centre of the glass to about a quarter and sometimes will be back up to halfway where it should be.Its an aftermarket carb which is identical to the Aisan 22B carb which was on my car.Is there something i can do to make the plunger fit more snug in the tube?? The accelerator pump squirts as it should
