I noticed water in raycor filter and engine stopped running. Will address that problem later. Question is how do I clean fuel system from gas bulb to carbs to get water out so that engine will crank?
Buy fresh fuel, put it in a small deck tank, open carb bowl drains and start pumping. Some sort of dye in the fresh fuel will help indicate,
and certain additives impart a color to the fuel, startron is blue for example.
