The thrust washer has nothing to do with it. It is the clearance between the bushing and the crank. With no more time than you have on hte motor, it isn't worn. Just get some good cleaner and just fly it.

Most two stroke glow engines dump a bunch of oil anyways. Even the glow four stroke can make a mess of things, but for the most part, that doesn't mean that they need repair. If it ain't broke, don't fix it.
