Engine Cleaning - How to Do It? After a crash etc.

Question: I have had a crash into dirt, sand, grass or other loose material and some of this debris is all over my engine and may have worked its way inside the engine. How to do I clean the debris off and out of my engine?

Answer: Wear eye protection and rubber gloves. Work outdoors. Invert the engine. Carefully rotate the throttle so that the carburetor barrel is closed. Plug the carb inlet with a wad of paper towel soaked in Oil. Clean away all of the debris from outside the engine using a tooth brush and Fantastic diluted 50/50 with water. Remove the muffler, the glow plug, the back plate, the prop nut, the prop washer, the thrust washer, and the carburetor. Flush the crankcase with Pacer Degreaser while holding the engine slightly nose high. Flush the cylinder via the Glow Plug hole while holding the engine with the exhaust outlet facing downwards. Flush the Front Bearing while holding the engine nose down. Flush the carburetor with Pacer Degreaser. Let the engine dry. Lubricate the crankcase and rear bearing with Pacer After Run Oil. Lubricate the crankshaft with Pacer After Run oil via the carburetor inlet in the crankcase. Lubricate the carb barrel with Pacer After Run Oil.

Turn the engine over several times by hand. Flush all parts again with Pacer Degreaser. Let dry and reapply After Run oil liberally to all internal components. Re-install the crankcase back plate and the carburetor. Reinstall the thrust washer, prop washer, prop nut and glow plug.
