Sounds like an air leak in the intake somewhere. Check all gaskets in the intake; manifold to engine, manifold to carb, carb to air box. Try some gasket sealer if gaskets show no damage.

I finally pulled the piston out to check the rings. The lower rings are not wider than the piston anymore. I'm guessing that is allowing oil to be pushed around the piston.
I ordered new rings and a new gasket set to put it back together. Hopefully that will take care of the issue. |

When you put in a new piston and rings did you sand the glaze off the cylinder wall? The rings won't seat against the cylinder unless you do that. A new cylinder has micro grooves in it from the boring bar but a used cylinder doesn't. Had you kept running it the rings and cylinder would have seat eventually but it would have smoked for a while.
