Blue smoke could be an overfilled oil res.

I copied the following from another rv tech post onan 4000

The carb on 4KY has a seal washer on INSIDE of float bowl, where fuel solenoid fitting comes through hole in bottom of bowl. If you have bowl off carb., and are not careful, or don't know this washer is there, it is easy to lose it.Then carb will not work correctly, will overfuel, etc. Might be something to check out. (been Onan tech 20+ years)

Another problem could be the fuel pump.
