You might want to chang the oil twice to get the gas out.
Nothing harder on a motor than gas on the bearings.
Except for a loose nut behind the wheel!

A very common occurence for us in the North, usually happens when a car won't start at about 30 degrees below zero and floods out.Also can be caused by a problemed carberator.

If it's happening do to flooding (ie overloading carb) how does it actually get into the oil?

First, I don't think it would be due to flooding as I didn't post that answer....... but......

If the manifold gets excess gasoline, it can seep past your piston rings through the gaps of the rings. It does happen, but you would really have to be flooding a lot to have this happen, and I think you would have noticed major starting problems before noticing this! I agree with the guys who suggest your fuel pump.

usually a bad fuel pump. hole in the diaphram allows fuel to drain into yhe crankcase.

It did run reall bad one day about two weeks ago, but new plugs and wires fixed that. I'd had two wires get against the headers. I'll try a new fuel pump.

I think you may have helped my case for flooding when you say you had a running problem a couple of weaks ago, a fouled spark plug is what often leads to the flooding, one can get glazed over if it is not firing properly-the situation you describe with the wires hitting the headers would have provided ample oportunity.I would check the plugs on those two cylinders as well,if you haven't already, they still may not be firing properly.
