Have a look in the air box too. If it was over filled with oil there would be a good bit of oil in there but I think the plug you pulled probably rules out the way too much oil theory. I'd expect the plug to be black and wet due to oil getting force past the rings and to see multiple wet plugs not just one. If there's only one fouled plug and the rest are normal then there's a problem in that one cylinder. How did you drain the coolant did you pull a hose off or use the drain bolt? I'd suggest pulling the lowest hose off just to be sure that there's no gunk in there. A leak down tester would be really useful here. It would pin point where the problem is without taking the engine apart. You need an air compressor to use it though
