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.

      Landmaster LM200 Will Not Start
      By BWF
      I have a 2011 or so Landmaster LM200.  I cannot get it to start.  I turn the key and nothing happens.  The brake switch seems to be working, the ignition switch works.  The Coil is new the Voltage Regulator is new and the starter relay is new.
       
      I can connect the terminals on the starter relay and it starts right up and runs fine.  I just can't get it to start by turning the key.
       
      I am having a bit of trouble bleeding the brakes, not much fluid comes out at the calipers when I am pumping the brakes, though that an air bubble near the brake switch might make it not sense that the brake pedal is depressed.
       
      I am at a loss, please help!

      I heard there's several off road festivals out that way. One or two post apocalyptic, the rest just rev and run. Anyone know a good one that offers camping? Any advice for out of state people like hauling, legality, and where to stay?
      Ideally me and the missus would be down for camping out and setting up shop somewhere nearby. That way we can just wake up, load up, and ride.

      MSU 500 Fuel Pump Ground
      By Kierobi
      Have a MSU 500 that we got from my wife's uncle a while back. We've had it running and hauling around the property but it stopped a few months ago after what I thought was running out of gas and I'm just getting to looking into it. 
      Had fuel to the injector but nothing coming out the injector so swapped with new injector and installed inline filter in the supply hose from fuel pump. Tried again and still nothing but noticed this time that I can't hear the fuel pump priming. 
      Pulled off the electrical connection and I'm getting 12V to the fuel pump but it won't run. Put it on a test bench and got it to run so put test lamp between +ve and -ve terminals on the connector and nothing. Checked against the passenger seat securing post and get a light. 
      Tried chasing the wire back and think that the ground is through the ECU but not 100% sure. Can someone confirm for me? And if it is through the ECU, is the ECU just grounded against the frame or is it wired through to the battery?
      Thanks in advance and hope this all make sense!

Can I use your typical vehicle code reader or do I need to download something on a laptop or PC???

      Utv wont start and broken fuel injection wire
      By Jeff freeman
      I have a Coleman 550.  Was having problems to start with where it would start and then shut off after a couple tries. It would take off and be good. It then got to a point where it would not start at all. I replaced the fuel injection twice the second time I replaced it I noticed a mouse or something had chewed one of the wires that connect the electrical to the fuel injector. . So two-part question first does anybody have a part number for that wire harness?  Second, any other ideas after I fix the wire harness permanently on what could keep it from starting I have gas flow up to the fuel injector.
