I have rebuilt many carburetors throughout the years, so that is not the issue. When my Onan started running way too rich, I ordered a rebuild kit from Jim K. I found several issues with my carb when I removed it, including several patch areas of epoxy on the body (?), a nozzle boss that looked like it had seen better days, a ground off idle screw, a bent float, etc. I have a NOS Walbro LMB carb, that I cannibalised to get a new float. The NOS carb did not have the same jetting etc, that the Onan employs so I could not use that carb. I put in a new idle screw and the repair kit, installed the carb back onto the Onan and it started and ran, but it is still too rich and cannot be adjusted at the idle screw. The power screw adjusts great. The Onan puts out the correct voltage and frequency at load and no load. The idle smooths out a little whenever the filter is removed (new filter) and the carbon is removed from the new spark plugs.
I believe there is internal damage in my carb and it cannot be rebuilt. If I can buy a used carb from someone at a reasonable price I may be able to rebuild and use it or use it as a core for a Jim K unit.
Thanks,
Jerry
