I woke up the other morning and my cub smelled like gas. I beleive that the float stuck open on the and it filed the crankcase. I drained all the fluids and pulled the old carb off and found that it was a Walbro. WhenI removed the bowl i found that the casting were the pin goes through for holding the float had been JB Welded on one side of the casting. Some people. I am looking for a diferent carb for it now and have been advised to switch to a Carter over the Walbro. Anyone have a thought.
