Onan Quiet Diesel questions

Steve Polhill · 08-14-2020, 10:32 AM

Anyone out there have any expertise on the Onan quiet diesel Gen sets with the 3 cyl Kubota D722 engine?

Ours is having a cold start issue. sometimes it needs extended cranking, Runs rough for 10 seconds or so before it straightens out. Huff's a bit of white smoke on start up. If I didn't know better I'd say it was flooded a bit. Once it straightens out ir runs fine for hours, makes power etc.

I've had the injectors rebuilt, it has all new filters and lift pump, New glow plugs etc.

Any one have some insight?
