I'm trying to identify this generator through photos. I know little to nothing about it or the model.
Thank you, corey

MEP 0016B or E. If Yanmar engine then E.

I agree 016B. the original motor was onan but they stopped manufacturing the motor. Then the military outsourced the yanmar with several adapter parts if the onan failed.
