MEP-XXX 3KW Generator Engine Problem

[rboltz]

Got a new in the crate 3KW generator some weeks ago from GL. It ran fine untill recently. Still runs OK but after about 10 minutes, it starts emitting dense blue smoke. This smoking will start and stop and comes from both exhaust stacks so it isn't one cylinder doing it. It appears engine oil must be getting into the intake or exhaust manifolds somehow but I can't figure out where. Anyone ever experience this?

Have you tried adjusting hte carb now that its broken in?

It's not running rich, it's oil smoke. Is there some way oil can get to the carb?

 

[rboltz]

Found it. The engine oil is full of gasoline. The fuel pump must be leaking gas into the crank case. Then, it must be causing the diluted oil to burn.

Yep, that'll do it...
