We recently bought one of the original model waverunner, and it is doing really well.

It has a fuel shut-off with settings Off, Run and Res (reserve) . . . just like my 1968 Yamaha 80 motorcycle did.

Now it only runs on the RES setting. If you set it to Run, it dies.

Any ideas?

Thanks.

Anyone? ? ?

Haven't had to tear into one of those yet, but I assume they are similar to what was used on the older motorcycles. Your line is plugged at the petcock where the on/off/reserve is or between there and the tank, or in the tank. I would start by draining the tank, tracing the hoses from the petcock to the tank, and taking that assembly apart for cleaning. There may be a screen similar to the ones in the old motorcycles. A less favorable option would be to force air backwards through the hoses into the tank, but that would leave the garb that's clogging it in the tank.

Thanks.

That sounds like work . . . & since it seems to be doing fine on RES . . .
