RE: OS TM leaking fuel from crankcase
It's normal to see a small amount of fuel coming from the front bearing. On an R/C car, you'll usually see a "stripe" below the engine and on the body above. If the oil didn't come out there, the front bearing would be getting no lubrication.
If your engine's throwing a lot of raw fuel from the front bearing, enough to actually put a film of fuel on your hand, then it's not the front bearing that's the problem, but the fit of the case to the crank. On R/C cars, the close fit is usually eroded by dirt. The only fix is a new crank, case, or both.
