Toss some gas or spray some carb cleaner/starting fluid down the carb throat.

spray it where the duct from the air filter goes to the carb. Then try to start it.

if it does fuel is not making it to through the new carb.

next take out the spark plug and spray some carb cleaner or pour a small amount of gas down the hole, put the plug back in. And turn it over.

if none of these give any results  lift the bed and  unplug the coil ground wire, it's right behind the governor linkage. Then try to start it.

if you want I can upload you some troubleshooting  pages from my shop manual to look at.

Next you might try to unhook the fuel line coming from the pump, to the carb, turn the engine over and gas should shoot out of the pump.

one of the least likely options would be to pull the valve cover and  be sure the valves are operating correctly/not out of time. thats a last last resort.

Here is the coil ground wire. Unplug it right there. Black wire

It's next to th oil fill cap.

As far as I know, no.  Did you look at kawasakipartshouse.com ? O EM parts, but a bit cheaper. I'm rebuilding my 550 now.

What parts were missing? There are quite a few 1000 parts on Ebay.

I did find another issue and it started...it does idle good but has a very severe hesitation on acceleration...i did put on a new omw carb. Hardly has enough power to move...any thoughts?

It could be sucking air from somewhere, or not getting good fuel flow enough to accelerate. Did you put new gaskets with the carb?

I would also add be sure your choke is fully opening and closing.

Okay.

If I am not mistaken there is 1 or 2 gaskets that have a small hole in the corner of them that match up with corresponding holes in the carburetor. But I may be totally wrong it's been almost a year since I put the carb on mine.

Yes there is the small gasket in between the engine and plastic spacer..then the main gasket in between carb and plastic spacer...in question.. That 2nd gasket has indentions..which direction do they face...towards engine or carb...

Posted

I did check and gaskets look correct...i adjust air fuel...seems idle ok...but eventually it does die...you can pump the gas and get it going and then it runs on down the road..

Hey Travis..Im a diesel guy so I'm not much into these faders but I did swap engines and components...do I need to adjust that governor lever as I did exchange that as well??

couldn't resist! Do you have a fuel filter on this model? Could be clogged.  Also any small crack in a fuel line can do bad things.  Does the engine have points and condenser or the newer electronics?

This engine has a ignition coil on the flywheel, no points.

Its possible, as old as these engines are, (15+)  I would buy a inline spark tester, like one you would use on a Briggs engine,  this is one like i have. you  hook it up to the plug wire, and clip it to ground, or on the spark plug, if you've got a orange, yellow spark, coil is weak, if its blue or white, thats great! another thing could be a faulty spark plug, sometimes under higher pressure (such as revving the engine) the spark wont jump the gap, the plug i use on the 550 is NGK  i BPR5ES. i would also be sure the plug gap is correct, should be 0.028-0.030, you might also try gapping it slight smaller than spec, if your coils weak it wont have enough oomf to jump the gap over high pressure. EDIT: one thing i would do, is when it starts to bog while revving, choke the engine, about 1/4 of the way, then half choke, then about 3/4  of fully choked. if it runs better while being choked you have a lean mixture of air and fuel. or more air, not much fuel.

Yes...that is correct....it will just stutter etc...I did notice the spark is Oran g ish and it seems to weaken after spinning the engine over after 10-20 seconds.  I ordered a new coil for it. I did take an empty cloth and shine up the magnet...reset the gap to .0012 per spec's. So hopefully that will fix it.

      I have a 2016 550, ive tryed the hisun website and seems i cant get parts there. I would like to add power steering, have seen a few "kits" on ebay
      for the 750 not sure if its the same parts needed for the 550, there is a factory bracket already welded to the frame above the standard steering rack, is this to be used
      to mount the eps motor? There is also a grey plug hanging just above the brake master cylinder, not sure if thats anything that needs to be used in the install.
      Handy with wrenches so if i can find the parts installing it shouldnt be a problem, anyone done this upgrade, was it worth it?

      Hello All...
           Just bought a 2014 Massimo 500 UTV.  It;s not running at the moment, but hopefully will soon.  I need a seat for it also (passenger side, if it makes any difference.)  It is a crank-but no start situation.  Just now starting to read the boards for solutions.  Apparently these models are well known for this issue.  If anyone has any suggestions, please feel free to chime in, it would be greatly appreciated.
      Thanks

      I have a Coleman HS400UTV-5 got it manly for hunting and spending time with the grandkids
      The one problem I am trying to avoid. My son borrowed it last summer and said it ran hot so he added water to it . I do not know how much he put in so I would like to drain most of it and add new coolant to protect it this winter. I can find no drain cock or any way of draining it besides loosening a hose.  Any suggestions ????

      I have a Coleman Outfitter 550 purchased in January 2022 that runs and operates pretty well.  65 hours on it so far.   It is a work vehicle for my 10 hilly acres with two 1 acre woods and 5 acres of "lawn".  The rest is under a lake. 
      My parking brake does not seem to have any grip.  It worked when new but after a month or so, it is just almost useless.     I press the parking brake pedal hard until it stops. Still, it won't hold even on slight inclines.   I don't see the caliper move as I press the brake pedal down.  There seems to be plenty of pad left on it and the rotor is shiny as if it is rubbing a little when applied, but not enough to stop it from rolling. 
      Any thoughts on possible causes?
