Tim,
I just happen to have a new fuel valve that I will put on mine whenever it warms up around here. The one that came on mine was leaking a bit so the dealer gave me a new one. Here's how the line go as you face the switch:
Upper left is vacuum
Lower right goes to the carb
Middle right comes from the tank reserve
Upper right comes from the tank main
I have noticed that mine is very cold natured. It always starts right up but I have to play with the choke and throttle to keep it going until it warms up.
Hope this helps, let us know.
CC
