Question about Yamaha 12V Air Pump
Hello, My 1994 Yamaha Waverunner 3 will idle but wont take throttle. It overheated when I pulled sand into exhoust. I cleaned exhaust out and took it out and it ran fine for 2 hours, now it will not take throttle. I have changed fuel lines,filter, rebuilt carb, rechecked rebuild, and still no change. Question: can the thermo switch have gone bad from overheat and be sending bad reading causing limiter to kick in. If so how can I check thermo unit to see if that is problem, It is an expensive part to change without being sure. Thanks, Don
Switch to reserve tanke to check to see if there is a clog at the fuel pickup in the tank.
My friend had the same issue with his waverunner 3.
