Sounds like one of the wires broke or got pinched. I'd trace the wires in the harness for the sensor for starters. I think there's a procedure for checking the voltage at the harness, but the TPS has to be plugged in while you do the test.

Thanks, I must have wrong TPS it only touches it when the throttle is wide open. There is not other way to get it to fit. Back to the parks store I go..

Interesting the OHV and SOHC TPS have opposite rotation. I wouldn't have known without searching this great forum.
