if you have to pull the choke, your engine is not getting enough fuel.

I've noticed carb problems on these 550s tend to happen quickly.

the first thing i would do is remove the fuel line from the carburetor and make sure the pump pumps when you crank it over, it'll shoot out in bursts.

if that looks good, i would remove the carburetor, two 10mm nuts, 10mm bowl screw, and spray out the main jet and all the air holes in the venturi with carburetor cleaner

I had recurring problems with my  carb since the fuel tank is a little rusty, getting rusty looking sediment build up in the bowl.  i installed two filters, one before the pump and one after the pump and i have had no more issues.

      2017 TW450 Kohler ECH440 runs out of fuel when running wide open.
      By Sammy
      Runs fine just putting around the yard. Get it out on the road and about a half miles it runs out of gas. Let it idle for a few minutes and it will run for another half mile and do it again. Replaced both fuel pumps and filter. Does anyone know if I can get rid of the factory fuel pump?

      Bennche 500, replaced stator no fire
      By Hoppy one
      I replaced the stator on our Bennche 500 because it was not charging. It ran as long as you kept the battery charged. I replaced the stator now it’s not firing. The only problem I found was a wire in the new stator for the crank position sensor was in the wrong place in the plug. I switched it around but still no fire. Putting a meter on those wires and cranking the motor showed no voltage from the crank position sensor. Something I did or a bad “new “ part? Thanks for any ideas.

      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.
