    sounds like pv reference hole

    how does the pv gasket look?

    have you tried a different pv?

    have you checked the fuel level in the bowls?

    It started doing it so I thought it was pv got a new one installed with new gasket and still doing it.

    I haven't tried any different pv as far as size

    fuel level is good in the secondaries but the primary will fill up then I can shut fuel pump off and watch the fuel bleed off in the sight glass and it just dumos into the intake

    thx greg

    have you done any drilling on the carb?

    maybe try a new metering block and bowl gasket

    double check the acc pump passage seal between the metering block and the main body
