1997 suzuki lt250F 4x4

[phazer2000]

This last weekend I bought a 1997 lt250f 4x4. I got it home and the family ran it around the yard for a few hours ran great. On sunday my son wanted to run it again. When he started it it started up and ran fine until it warmed up. Once it was warm it would not run past half throttle maybe not even that far. It sputtered missed and eventually died. I pulled the plug and the it was black. Seams to me it is running rich. I am not familiar with the carbs on this machine and do not have a shop manual, but the only thing that I could think of was that the choke is stuck part way on. Does anyone know what I should try first???

Thanks for the help.

Possibly left the choke on put new plug in start it up if not possible choke sticking or dirty carb

It was a choke issue. See picture of dirty choke part.
