What should I do if my engine is flooded?
If you try to start your engine, and pull and pull, but it doesn't start, but only "pops" once in a while, it's flooded or too rich. Before you can hope to start your engine, you will have to get rid of the excess fuel.
First, gently turn the high-speed needle valve clockwise until it just stops. Carefully remove the glow plug from the cylinder head. Open the throttle to full.
Place a rag over the top of the cylinder head to catch any fuel that will be spit from it, and so that none of that fuel will get on your face or in your eyes.
Pull the recoil starter in brisk, short strokes to work any excess fuel out of the engine. When no more fuel will come out of the cylinder head, stop pulling the starter, and let the engine rest for about 10 minutes to let any remaining fuel evaporate.
Carefully replace the glow plug and attach the battery. Make sure the car is held so that it cannot move, and pull the starter. After a few pulls, the engine should fire. It will fire and run a very short time. This means it's ready to start. Pull the recoil one more time. The engine should again fire and run a very short time.
Now open the high-speed needle 2-1/4 turns, prime the engine until the fuel in the line comes up just to the carburetor, and try pulling the recoil unit. The engine should fire within a few pulls and continue to run. You can now drive your model and get the needle properly-adjusted.
