I have been working on my 292 for a while now and for a while have had an issue with my idle/mixture or something else. Today my vehicle after installing a new water pump, and thermostat, I took it out for a run. On the run I finally figured out it is wanting to flood at stops, but that is getting ahead of myself. I take it out and run it and back off the choke as it it warms up. At the first full stop I figured out it was flooding when I saw the big billows of black smoke I saw pour from my exhaust as I turned it over with pedal flat to the floor. Previously I turned the screw completely closed, backed it off and then leaned it out until it started to rough up. Anyone have any ideas? I have one person thought it might be dirt in the needle seat. Need to look that over.

Dirt in the needle and seat is possible. What carburetor are you using? When it's running can you look down the carburetor throat and see gas dripping? That would be a sunk float.

Martin is probably right, a small 'speck' of dirt/rust is holding it (float-needle) open. Check/change your fuel filter. Good luck.

Check your tank too. You might have some sediment or rust that will keep getting sucked in making this a reoccurring problem.

When you pull the filter element, you'll know.  If (that word again) It's clean in there and in the bowel. Change the needle/seat and adjust the float. Then turn the assembly 'upside down' & blow through it to make sure it is seating. Good luck.
