BE VERY VERY VERY VERY CARFUL DOING THIS !!! you could hydrolock the motor and bend a rod/rods :???: just put it in your fuel. i only use LUCAS or B12. i like the LUCAS ALOT :grin:grunt said:You can also remove the air cleaner with the engine off and pour it in the carb with the throttle open to remove carbon. Let it sit for 5 minutes and start it up in an open area cause there will be a lot of smoke.
