Engine RPM problem--Help! When I apply full throttle from a standing start both engines react and the RPM jumps up to around 7200 on both engines but then the right engine falls back to about 4800 RPM and will not go any higher even with full thottle applied. Is this a Rave valave problem? Anyone have any ideas? I have just replaced a fuel pick up at the tank but both engines ran fine for a couple of hours after I did that and then this problem started. Help guys....
