I'm looking at buying an Onan genset. It's a late 80's vintage 4 cyl aircooled diesel unit, 120/240 single phase. Seems to be the same model unit shown here-
As far as I can tell it has about 1500 hours on it since it's last rebuild. I had the seller fire it up today & after warming up it was blowing white smoke . The owner sez it was fine last time he ran it back in June. It also seemed to take a while to settle down before it ran evenly although there may have been some air in the fuel line.
Q.- Any ideas what the white smoke is all about? Is this likely to be a tuneup item or something more serious?
Q.-What's a rebuild on one of these things cost?
Q.- Anything in particular I should be looking for/concerned about with one of these units?
Q.- How much do you think its worth?
Thanks,
Howard.
