Re: Sport Jet 120 Problems (Go Figure)
Do a compression/spark test.Check the fuel pump filter and diaphram.What's a ride plate?Post a pic.The section for PWC has a guy calls himself kend301 he's up on this stuff.The motor is a Force 120 powerhead(I believe).Simple diagnostics are the same.
Ethanol is messing up a lot of motors.It's delaminating the inside of older hoses causing clogs in the carbs and fuel filter.Check for soft hoses and junk in the filter on the motor.Check the diaphram.
Do the tests and post your results.J
