Holly Doulbe Pumber Leaking
Holly Doulbe Pumber Leaking
(OP)
Hi
Have just purchased a jetboat with a 350chev with a holly double pumper on it. When at idle the fuel seems to drip from the jets down the barrel. We have put new gaskets between the float bowl and the barrel, made it idle a little better but we still have the leaking. I just read something vague about the power valve could be the problem. I am new to big engines the biggest I have worked on before was a Honda XR600. Thanks

this is a marine carb. as all marine Holleys Iv'e
seen are vacuum secondary units. There are a lot
of subtle but IMPORTANT differences between the
marine & automotive units.
