Old engine help
I just was given a few old gas powered control line engines that I would like to get working. A few of them are seized up and I was wondering what I could soak the engines in to help free them up. Thanks, Chris

RE: Old engine help
Chris, I've had good luck with a heat gun and penetrating oil. This will free them quick. Once they are free, flush the engine with fuel to remove the penetrating oil. Over time, penetrating oil will damage neoprene and silicone. A hair dryer will also work for a heat source. I've also read that putting the engine in a pan of boiling water will free it quick. The same flush with fuel would be required to remove the water afterwards. I plan on trying the boiling water method next time I'm faced with a gunk frozen engine.
