to start i'm talking about the 86 shaft drive

heres whats wrong
it blows gas out a vacume line. I was putting some compressed are through the fuel line now the line the comes out of the top of the carb shoots gas out of it. should the other end of this line go to some thing or is it just a vent hose?

help!!

 

Either a vent hose or an overflow hose. Shooting gas? Or pouring gas out of the tube??? Pouring out is caused by the float needle not sealing against the seat and shutting off the gas flow. Try a few raps with the handle of a hammer on the carb to dislodge some dirt.
