I have a Kohler 25 mud buddy lt. it's a 2000 model with low hours. First few times I used it it ran great. However recently been experiencing issues.

Motor will fire right off cold. After running hard for a while if I idle down low it will try to choke out. I can keep it going if I give it throttle. If it does shut off it's hard to start and usually end up flooding. If it cools down it will fire right back up again. If I can get it lit off while hot it misses and runs rough. Also when I pulled the old plugs out they were carbon fouled.

I'm gonna rebuild the carb and go from there I reckon

Any suggestions or tips would be greatly appreciated thanks
