If anyone has not complied with the above bulletins, I would advise you to do so ASAP.
The float in my circa 1997 A10-3878 Marvel Carb float did not sink, but the needle valve plunger dug a hole almost halfway through the adjustment tab on the 30-764 float. The float was barely shutting the valve when the float hit the gasket. The float to gasket distance when closed should be .200" (13/64"). The replacement float for this carb is 30-862.
Early indications of this problem are engine flooding during closed throttle.
