Hole in the float? Float hanging up? Just a couple things I have run into. Good luck.

When you first started after cooling down it idles fine, high and low. Once I move it or engage PTO it floods out
How do you know it is "flooding out" and not an ignition failure?
Gas dripping from carb? .....Sooty, black smoke from exhaust?
When it cuts out, is the sparkplug wet or dry?
Have you verified the presence of a strong spark right after the engine cuts out?

wet plug and it backfires when shut down
I've heard of a lean mixture causing a backfire, but I've never heard of a backfire being caused by a too-rich mixture.
Backfiring through the carb is usually caused by an intake valve not seating properly, or improper ignition timing.
Backfiring through the exhaust is usually caused by an exhaust valve not seating properly or improper ignition timing.
The wet plug can be caused by flooding, or by faulty ignition (loss of spark).
Wisconsin engines are very sensitive to ignition timing, so setting points with feeler gauges is usually not good enough.
If you are losing spark, I'd start with a new condenser. ....The points can be cleaned, reused, and reset unless pitted.
The best way to adjust the points is with a continuity tester or test light to get the timing correct.
