had a crash sunday repairable and the guys at the field told me the engine was fine, but didn't bother to start it up. anyway i noticed today fuel dripping off the prop, its coming from the crankshaft, is the bad or is that normal?

If it wasn't doing it before the crash, then it's probably bad. What kind of engine is it and what kind of glow fuel mix are you running it with?

its a GP 42 running 15% coolpower and I don't think it did it before, still seems to have the same good compression. has anyone else had an engine do this?

did you empty the fuel tank after the crash?if not you might want to check the crankshaft being bent.if you left fuel in it that might be filling into the carburator and leaking out from there

I agree with Horace you probably had fuel left in the tank and may have stored the model nose down. There's nothing to stop fuel running out the front of the crankshaft other than the very small clearance between the crankshaft and the crankcase. It's quite normal even for a ball raced engine but I think yours is plain bearing in which case you shouldn't be using Coolpower fuel. Plain bearing (bushed) crankshafts need at least 20% oil and the more castor the better. Ideally they need 22% all castor for very long life.

I just use the fuel I was told to use. I emptied the fuel out but there was that little bit that is hard to ge out.

is there any more play, side to side, in the crank shaft than before the crash? If so you probably got the front bearing, should be replaced.
what kind of crash did you have? Nose down?

As a rule of thumb, I always run an engine dry at the end of the day. This way, there's no methanol or nitro in the engine to cause rust. If I can't run it dry, I'll pull the fuel line and make sure I empty as much fuel out of the engine as I can and then add some after run oil. If I have the misfortune of crashing, I make time when I get home to clean and inspect the engine so I don't put it away with fuel inside.

And this prevents the accidental dripping of fuel onto your floors or carpets.
