My Honda 450 Foreman is leaking fuel from the hose coming from the bottom of the carburetor bowl. Is this hose supposed to be connected to something? Or is the 1 way valve in the hose the problem?
This problem can occur on any bike that is carburetted and uses a needle and seat/float bowl system. Basically any bike that isn't fuel injected in other words. The reason fuel is being dumped is because it isn't getting shut off and is flowing past the needle/seat. The cause of this is one or more of the following. Dirt or foreign material interfering with needle/seat/float operation.....Worn needle and/or seat....Malfunctioning float due to leaking float...Is there any thing in the float when you shake it?......Lastly, and I cannot stress this point enough,.....Improper float level setting. This is a critical setting and must be set as accurately as possible according to manufacturer's specs. It is accomplished by bending the tang of the float which will control how much fuel will be in the float bowl when the float bowl is full. Think of a common toilet with a float mechanism because it is the same principle.
