if fuel is dripping when you turn the fuel on and not when you prime it.

most likely either the needle is not seating properly in the seat (could be dirt or gunk buildup, The float is stuck or the float has a hole in it and has filled with gas.


removal and cleaning of the carburetor would be the first step in chasing down this problem.

Before going inside you may want to try using Seafoamģ in it. It should dissolve any gunk and run it through. Give it a little time to work.

I've seen where there's a tiny breather hole near the very top of the carb. If it gets plugged, fuel will fill the carb but it's air bound because the breather is clogged. It'll blow fuel out the jet inside.

Yep. Thatís the tube. Put in a new needle/seat and delivered it. It still gets a little gas coming out of it when you prime it, but canít do anything about it now as itís 250 miles away from here. Thanks for all the help.
