Try taping the float bowel till the pins let loose and the floats re-float. This happens when you don't put stabilizer in your fuel and your engine sits for extended periods. The ethanol in the fuel causes a green sludge build up in the carb that makes the float pins stick . give the float bowels a tap with hammer not hard you just want to free them up . you may want to pull that pumper apart an clean the jets and needles and the float bowl reservoir. Hope this helps

Tap trick worked and I decided to put a carb kit on it so i cleaned it out and you were right about the green scale. I'll have to remember to use a fuel stabilizer after this.
