I already drained the bowls and waited to see if they would fill up again. No go on the bowls filling up again. The fuel line from the tank to the carbs and filter were clear. The only thing I can think of is maybe the float bowls are stuck not allowing fuel into the bowls. I plan on removing the carbs and cleaning them then reassemble and test them. I'm checking with my local dealer now to see if they carry the stainless socket head cap screws.
