I've had this motor for two years...no problems, very clean motor. Last week I noticed the cooling stream was sputtering a bit when idling, and eventually it stopped. I restarted the motor, ran it for about 30 seconds.....no stream. I removed the motor and replaced the impeller....only 3 blades were intact, and cleaned the pump housing/tubes of debris. Now the motor will not start. Checked the compression....95 on both cylinders after three pulls. Is this low? I know it's getting fuel.
