Looking at the carb float bowl from the left side of my 6000w Onan, at the very bottom of the bowl there's a brass needle valve with a flat on one side staring you in the face. Not sure what it does, but gas was dripping out of it today.
I counted the number of turns in from where it was set, then took it out to find the rubber(?) seal to be a bit hard and slightly chewed up.
When I tried to remove the seal from the valve, it snapped, so I took some electrical shrink tubing and shrank on and trimmed three layers of the stuff, ending up with roughly the same profile and shape as the broken piece. Any port in a storm etc.
Fortunately, after I reinstalled the needle valve with the "new" seal, there was no more leaking and the Onan fired right up. Tried it again once or twice a few hours later and all was still good, with Genset starting immediately each time.
What is that valve's purpose?
