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.

      Bit of background. First the machine would take for ever to start. So I adjusted the valve shims into spec and made sure the timing is correct. Starts perfectly now. 
       
      now it fluctuates on idle. Bogs down, Revs up, repeat. I noticed the fuel pressure drops from 60psi to 20psi while that happens. It also bogs down at the lower end of each gear, higher rpm seems to be fine. Seems to struggle under load. In neutral it revs up perfectly. 
       
      brand new fuel pump, fuel filter, gas. I noticed on the fuel pressure regulator there’s that vacuum nipple, it’s not attached to anything and I’m not sure where it would go. Possibly the problem? 
       
      Another issue is the tip off the end of the exhaust is broken off, sensor is still attached and connected. Could that cause these issues? 
       
      my next plan was to look into the pressure regulator and voltage to fuel pump while driving. Is there anything I’m missing or any ideas you guys have? 
       
      thanks!

      Recently purchased 2nd hand not going Crossfire GT400 (Australian branded name?) 2020 model.  Has some issues what would be the best forum to pose questions.

      Have a bed decal that has never been right.  Contacted Coleman Powersports and they have no solution.  Anyone know of a place where I could get a replacement decal or complete decal or graphics kit?

      Hello everyone! I am new here and have no experience with UTVs but I am quickly getting some. I have a shifting problem where I can shift through all gears without the engine running but as soon as I start the engine I can not select a gear. Yes, foot is on the brake and yes the pin is being pulled to go into reverse if I was to try going into reverse. The shift lever does not move. I adjusted the linkage to get more accurate shifting with the engine off so I know those are now correct. I opened the shift lever housing to inspect the teeth on the gear and found this picture below. Why is this oil so milky looking? I assume with oil like this I'll need to replace the wet clutch as well but am not positive. Does anyone have any input into how to flush this system and get things shifting correctly? Thanks in advance for all the help!

      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.
