OK not an auto but you guys would know

Old Cub Cadet heavy duty, shaft drive. Kohler in it. It "hunts" I blew gas lines out, replaced a 2" x 1.5" HD fuel filter, removed tank and flushed it. Carb is not a regular mower carb, looks like a single barrel or something. It had a big filter on it before it started acting up so not sure if carb float bowl. Ran a couple hrs then hunting again. Ideas?

Yo,

Lube all the linkages associated with the carbs operation for a start, including throttle shaft & its bushings.

I'd say replacing the carbs needle & seat, plus the fuel-float will likely cure your ailment IMO. ( Pictures of the carb will help. Different designs inherit different woes sometimes ).

Yo,

I'm hoping that first-off, you've checked & cleaned your air-filter element, & made sure that the choke-cable ( if applicable ) is releasing...

Hunting ( as you described / called it ) is often the result of too-rich a fuel mixture...( Too muck fuel, not enough air ).

I hope this helps,

Rastus

Tecumseh engines would have a surging when a carburetor port would get plugged up. Here is a video of the fix for a Tecumseh, Kohler may have something similar.

And here is a Republican's video on the topic (you can tell by the teeth)

I suppose you could have a governor issue too, but carb issues are much more common.

 Thanks Rastus. Changed the air filter not that long ago but it is very dusty mowing sometimes, I'll check that and the choke cable for sure. Either of those would sure richen it up.

Thanks men, got some things to try now. Carb is different, looks almost like a single barrel, very flat appears part of the manifold (of course it's not) but I'll find the jets and new air filter too.

Watched both vids. 2nd one is pretty funny, worth a watch. Taryl Dactal with his bubba teeth and about 20 pens in his pockets. I had a set of those, what a riot when I popped them in
