wont stay running

Had another recommendation from someone that said the valve adjustments could also be to blame. It made sense how he explained it. Gaps were indeed to small. Adjusted them and I also adjusted float more. Started right up on first push of the button. Idled better and lower this time before stalling, but still too high. Stuck my hand in air box and manifold was wet with gas again.
Perhaps the little rubber tip on the needle valve is worn out and not stopping the flow of fuel? Maybe PO used E15/E85 fuel? Maybe he used a carb cleaning solution that is not friendly to rubber parts? Petcock seems fine, and stops the flow of fuel when the engine is not running.
When I rebuilt the first time, I let it soak in one of those paint buckets of carb and parts cleaner for 24 hours, rinsed and sprayed out with Gumout.
I think I will order a new needle valve and needle valve seat, since it comes as a set, and see what happens. PO said the float itself was new, and it looks like it. Ill keep playing with it.
Thx
