Thanks for the fast reply. But, I don't have any valves on the valve cover, only a single (small) switch, the kind with a small roller at the end of a thin lever. The lever is operated off of the throttle levers. As far as tracing the 2 wires coming off of the switch - they go into a black sheath that goes down the side of the engine and joins up with a bigger bunch of wires. Anybody out there have this set-up?

Thanks

Steve
