Your best guess

Looking for opinions on whats up with my Landlord. I re-ringed the B+S engine and had a heck of a time keeping it running both before the rings and after. Ended up rewiring it and REALLY cleaning the carb. Now it starts and runs ok 'til you put a load on it or get on a hill. Then it'll puke white to blue smoke for a while. It doesn't appear overfilled on oil. Could it just be the new rings allowing some oil past? Or are there valve seals or something like that I missed?

Can you run the RPM up with no load? John
