Seat belt switch has been bypassed. But thanks for ideas.

Yes. Engine is running very smooth. It’s revs to 4300rpm but just is bogging down like timing is off or something. Belt is not slipping.

Okay folks. I have a low power issue. Been like this for a few years. Place I work at bought 3 and all have lost most of the pulling power. They gave them away after local shop worked on one for 3 months and it had great power for about 1 month and then crap. They replaced throttle body, fuel injector, spark plug and IAC motor. Seat belt switches have wires cut and left open so no seat belt warning light anymore. It revs to 6k rpm in neutral but when put in gear and take off in low it just doesn’t seem to want to go anymore. Running 93 octane fuel with Stabil. Any ideas greatly appreciated. I dont have a scan tool but no codes on dash. If held to floor it pops a little and runs almost 5K rpm but if I let off pedal about an inch it smoothed out and revs up to 6k rpm.

Got myself a 2017 Cub Cadet Challenger 500 for free. It has very low usage and runs like crap (no power going up hills, popping and running rough at WOT in neutral, only 32 mph on flat asphalt) but it was free right? I'm an old ASE Automotive Master Tech and drivability tech from GM that can't figure out a Hisun UTV motor and have no manuals on this thing. I have seen this thing run 45mph but it just started to slowly run more crappy each day. New air filter. I need help guys. Please.
