Since my generator is vital to our usage and since it is now approaching 1000hrs on the clock, I decided to look for a replacement generator just in case. Ended up finding the exact same version of my Onan Marquis 7000 for a great price that only had 15 hours on the clock. It was used as a backup generator for the owner's workshop. He converted it over to 240/120 operation. The other issue was that it was an LP generator.
In the end, I was able to convert it back to 120V only operation and convert it from LP to gas. Cleaned the slip rings, added new OEM carb (Not a Chinese piece of crap) and fuel pump on top of the usual filter and plug changes.
Load tested it to 6900 Watts using space heaters as a load. Should now be a direct drop-in replacement.
Ready to be installed when needed:
New carb and a fuel pressure gauge:
New fuel pump:
Really getting to know how these old guy's work.
