Hello, what can I take to clean my engines? I've tried a lot of things, but unfortunately the aluminum has turned dark. I would be happy to receive an answer.
If the cast aluminum motor has been isolated for years most likely the additives from the previous fuel have attacked the alloy leaving darken areas that have penetrated thru the alloy casing, there are a few options to remove some of the discoloration. What I have been using with acceptable result is Berryman 0996 Chem-Dip Carburetor Parts Cleaner within a ultrasonic cleaner at 50 Celsius (120 Fahrenheit) for about 30 to 45 minutes and then I rinse with hot water & soap (Dawn) and then freshwater rinse then let air dry. The hotter the air dry the better to extract any chemicals residue from the Chem-Dip to prevent any further additional discoloration.
Nice job
Nice engine. While much less powerful than today's 21-sized engines, the Enya 21X and 21CX are super reliable and easy on the gear boxes.
