Changed carburetor, but now have new problem - smoke?

Question

I have an Onan Marquis Gold 7000.  Float was bad so I put in a new carburetor.  New carburetor installed fine, generator started right up with no problem, producing electricity 118volts @ 62Hz.  Runs smooth.  But some smoke around the right side of the unit.  Almost like it is burning off some burnt spilled oil, but I can't see anything.  After shutting down, still continues to smoke a while till cool.   Anyone have an idea?

I'd assume it's just burn off. Run it for 15 minutes and the smoke should disappear. If it doesn't, gets worse, or starts to run bad, shut it down and disassemble to determine the cause. I worked for engines for many years. A little smoke residual hydrocarbons was the norm.

Have you checked the oil?  A bad float could have filled the crankcase with fuel.
