Dunno how this one got missed? Sorry man!

Typically if it's smoking the piston rings are worn out.

It is possible the reed valve for the breather system in the head is bad and is forcing oil vapor out into the carb inlet. Pull the intake tube off and look for heavy amounts of oil in the carb inlet.

Also possible the head gasket has failed and is letting oil leak directly into the combustion chamber. The best way to check all of that is to pull the motor, pull the head off and see if the head gasket has any visible failure points. Then check the cylinder bore for wear. Usually if the rings are toast the bore will be glazed.

A compression test can sometimes pinpoint bad or stuck rings, but usually it's inconclusive. The only way to know for sure it to tear it down and remove the piston.
