Hoping someone can help. I have a 1996 WXC 610, which I drained the gas and gave the carb a good cleaning a few weeks ago. Everything was disassembled for about two (2) weeks. When I put everything back together, fuel was leaking out of everywhere. I supposed the orings/seals dried up and shrunk a bit. I have replaced the rights side petcock / main fuel valve o-ring, and the carb o-rings/seals. Now, the left-side screw type fuel valve is leaking pretty bad. It simply unscrews to open up, and transfer fuel from the left side of the tank, over to the main fuel valve. In the closed position, it drips slowly. In the open position, it leaks enough that I do not feel it is safe to ride, leaking that much fuel right above the hot exhaust. Does anyone know how the left-side fuel valve comes apart? I assume there is a small o-ring inside that needs replaced. There is a small E-clip at the base of the knob. I removed the E-clip, but nothing seems to want to come apart. The o-ring at the tank/fuel valve mounting point is not leaking - it seems to be from inside. Any advise? Thanks.
