Chris,
What ever else happens, if you can't make it work, find a local small engine shop. You don't give any hint what it is, but Onan engines have been installed lots of places for a long time.
Next big hint. If it is a "Power Drawer", then I have another stop for you. These were installed in about 13,000 GMC motorhomes betweem '73 and '79 model years. Both the 4kW(BF) and 6kW(NH) were used. If it is one of these, then root around at the site and you can dig up a wealth of information about these beasts.
While many replace them because they are now old and were mistreated in their youth, many of us elect to just extend the effort to keep them running. It isn't very difficult to do.
