I have looked all over google and cant find any one that has my issue. My 139qmb wont start unless i drain the gas from the float bowl in carb. Once i drain it i kick it over untill it fill with gas and then i have a chance to start it. Some times it starts great amd fast. Maybe even for days. Then out of no where it wont start unless i drain carb and crank till it fills with gas again. Any one have any ideas? Carb just got cleaned, valves are adjusted and no air leaks in manifold of head or bottom end. Have 91 pump gas with slight octain boost/keeps gas cleaner. I have good flow of gas to carb and if i take vacuum line off carb and suck on it with gas line disconnected the gas runs outfast so i dont think vacuum line or fuel to carb is problem. Help hahaha
