Anybody knows whats wrong with a suzuki eiger 400 when it stalls out.I put the fuel selector on prime and it started back up,and ran fine.I have a full tank of gas.

 

you have a vac. line on the back side of the valve make sure it has no leaks in the line or carb boot.

if that is fine take the valve apart and check the diaphragm

the vac pulls the diaph. open and let's the fuel flow no vac no fuel.

the prime side lets fuel flow all the time tell the float cuts it off
