Put a new carb on the 500 to replace the leaking OE one.  Machine idles fine and mid and top end runs great.  It tends to have a hesitation right from the start - bottom end.   Thinking it may be the air/fuel screw??  I didn't do anything with the carb out of the box and is it direct replacement for my machine.  Of interest is the manual choke doesn't seem to work very good now.... wonder is it getting too much air?

 

Any help appreciated!

Just going to follow-up on this one.  I turned the fuel/air screw out 1/4 a turn (counterclockwise) and the hesitation is all but gone.  Might do another 1/4 turn rid it completely.  She needed more fuel.

It sounds to me that the acceleration nozzle (or pump) needs to be adjusted. 

The thing runs great at idle and mid and top range. It only needs more fuel when you open the throttle.

      I just purchased a used 2023 Massimo warrior UTV SxS 1000mx with 600 miles on it. I didn't even get a full day of riding and the driver's side rear axle broke. I'm pretty sure it was already going bad because we would hear a noise once in a while. I'm wondering if anyone else has had problems with theirs. Also looking for places to buy accessories.

      Coleman UT400 won't rev. Idles fine
      By Will Sutton
      I've got a 2023 UT400 (bought from tractor supply) and I've been beating my head against a wall with it.
      It will start and idle perfectly. The second I touch the throttle it sputters and dies.
      I've checked that the fuel pump is working  (it is).
      I've replaced the injector, throttle position sensor, O2 sensor, and intake air sensor. All with no change.
       
      I've just taken a look a the schematic, and there is a crank position sensor as well.

      Could this be the source of my troubles? If so, where is this thing located? I can't seem to find it on any drawings from the parts suppliers.
