    Thanks Alan. I am going to check gasolator today and
    Float stop. I haven't been turning off the fuel shutoff at
    all. Good idea. Thank you.

    This carb may just need the float control arms adjusted. The floats may be just fine. the arms in conjunction with the floats control the level of fuel and if improperly adjusted will allow fuel to overflow. The carb must be off the engine to check this. It is help upside down. The float arm should be 10.5mm from the edge of the carb bowl to the top of the float arm in vertical height. Place a mm ruler on the carb edge and slide it over so the ruler mm can be read and compared to the float arm. The ruler here is straight up in the air sitting on the carb edge. If you need to make an adjustment just tweak the tab that the float needle is attached to. Either a tweak up or down and then see if you're now 10.5mm. If you're that .5mm off that doesn't see to be a big deal, but you should also strive for perfection. :)


    p.s.
    You didn't say how old the engine was. Ifg it dates back to early 2000 or before time period it may have red needle valves that were supposed to be tossed way back then.
