RE: Engine Cleaning
Are we talkin' 'glo engines'?
I've had great success with a crock pot & anti-freeze.. to remove the caked-on burnt oil & nitro..
Break the engine donw to the basic componenets. Go buy a crappy crock pot at value village or what ever '2nd hand store' you have. Get a metal strainer too! And buy a jug of Prestone / Ethyl Glycol on the way home.
Put the parts in the strainer, and fill the crock pot with the ethyl glycol. "Simmer" the parts in the crock pot, on low, for a few hours, like a day.. And you should have nice shiny engine parts. Drain, oil, and re-assembled..
Oh, a do it in your garage!
