Anybody ever have this happen? My friend has a blaster we just finished rebuilding and the thing looks and runs awesome. He left the fuel on and we came back to it today and all the fuel is gone. We noticed some on the ground but not much. I started it up and it poured fuel out of the engine vent tube. I think the float must be sticking (and the carb overflow tube is clogged) and letting fuel into the engine. Anybody ever have this happen to them?
