Hi Hal,
There are several possible causes. It could be any ONE or some
COMBINATION of these:
- Damaged, missing, or improperly installed gasket.
- Float level set too high.
- Float needle valve leaking (wear, misalignment, debris).
- Sunk float (punctured or saturated).
- Wrong type of electric fuel pump (high-pressure).
- Electric fuel pump pressure/bypass problem.
- Possible warped carb body.
- Possible fuel bowl venting problem.
etc.
I suspect the carb is at the heart of this problem. However, we
shouldn't neglect the fuel pump as a possible source or contributing
factor. What kind of electric fuel pump do you have? There are several
types. Fuel pumps for fuel injection systems usually develop more
pressure and often require a return line to the fuel tank. Many
lower-pressure types would work fine for your application. Does the pump
literature say how much pressure it develops? Have you checked? Is it
installed correctly?
Solution:
1) Do a careful rebuild of the carburetor.
2) Check the fuel line pressure and pump installation.
3) Install (or replace) a fuel line filter.
