I have a 3010 with about 400 hours. It runs great and idles great but can be hard to start. Even at 100 degrees outside you have to choke it to start after that it runs well. Could use help so the wife can start it easier.

Try pushing the gas peddle down to the floor when starting, and let off as soon as it starts...my mule has been similar as long as I can remember, but hold the pedal down and it would probably start right up in the north pole!

One thing I would do is pull your spark plugs out and check them to be sure you aren't running too lean..

Travis makes a couple of good points. Weak spark can cause your problem also. Another possibility is the alcohol content in fuel. It can be hard on fuel systems. And cause problems. Especially if it's at 10% or more. Some machines are more affected than others. Some areas use a higher content. 

So I'd get a spark tester, that's made to see how far the spark will jump. They're not expensive. But just seeing if it's a blue spark isn't enough. Test all plugs, and wires. Pay attention to which plug came from which cylinder. That information might be needed. 

Good, clean, normal plugs. Good hot spark. If you have both of these, then it almost has to be a fuel issue. Of course there's other possibilities. But given the low hours, and condition of that machine. Most of the other possibilities seem unlikely.

      When we first heard the noise, we immediately stopped driving it...at first we thought it might be a linkage issue, but after further inspection looks like the sound/jolting is coming from the rear diff. Took a video below...
      Anyone know what is creating the diff to skip/jump like this? We drained the diff oil and didn't look terrible, no metal.
      Other info that may be useful:
      1400 miles on it
      Recently tightened the E brake
      P.s. never posted on this forum before, let me know if the video does not work

      Have a Coleman UTV 400 that cranks, runs, drives well until it gets warm and is put under load.  Light throttle or full throttle it doesn't bog, but it will cut out mid throttle if you move the pedal quicker than it seems to like for example when you're getting ready to go up a hill, but if you immediately floor it, it will do just fine and not cut out.  It's random if and when it's going to do it, but is consistent in that it happens only when hot/full operating temperature.  I've replaced the injector twice, same with the spark plug and tried different heat ranges (NGK 7,8 and 8 iridium), replaced the fuel pump, adjusted the valves, checked air filter which is like new, changed the oil, replaced the fuel filter.  No check engine light.  I don't have a code reader for this.  Initially I thought it might have a head or head gasket issue as when I got it, the oil was over full, very runny like water milky and it was smoking.  I've changed the oil since then twice to clear and clean everything out, and it seems to be good.  Coolant stays the same level and so does oil with no changes in consistency or need for adding more. Had I think 7-9 miles when I got it and now has about 77.  What should I try or consider next?

      Is there a better performing higher volume injector than what they come with or what is the best replacement for the original?

      Is there a diagram of all of the grease zerks for a Coleman UT 400?  Mine squeaks like crazy and want to try and remedy it.
