Test the buzzer by turning key on and gronding pink wire at temp sensor on head. Check compression and ignition spark. May need carbs cleaned.

May have bad wire in main harness. Remove the oil level sensor from oil tank with key on, buzzer should sound with float at bottom.

Check your exhast tube coming out of the jet pump.It probably has a hole due to corrosion. The hole allows water to limit rpm's due to back pressure in the exhaust tube. Take it for what its worth, this could save you some time and expense.
