I am having a really weird issue with my mule. So it is at my deer lease and stays down there year round and gets used only on the weekends. The issue I have is when I get there on Friday I start it and run it Friday evening and Saturday with 0 issues. Sunday it starts slow and runs fine initially then in a matter of minutes it starts crawling even when floored I think it is a fuel issue of some sort but the thing I can't understand is why does it run fine for a day and a half then all of a sudden it runs like crap dragging and not wanting to go anywhere. Then park it and let it sit until the next Friday then it is fine again. Anyone got any ideas.

      I'm working with a 2015 MSU-500.  Basic symptoms are it cranks well, but will not fire.  It has spark, and it has fuel spraying out of the injector (and spraying starting fluid into the throttle body and plug hole makes no difference).  It has compression.  I bought it not running, and no other information was available.  It has 775 miles on it and 127 hours.  It looks to be in very good shape.   Previous owner replaced fuel pump, ECU, coil, plug, and the fuse/relay box that mounts on the firewall, then gave up.
      My questions relate to cam/valve timing, considering the symptoms and diagnostics so far.  My thinking was the woodruff key sheared off and the crank spun, making it out of time.  My question is, by the pictures attached does anyone have an opinion as to the cam/valve timing being correct?  In the crankshaft picture you can see a timing mark visible.  In the camshaft picture I have arrows directed towards what I think are timing marks (which appear to be exactly 180 degrees from one another).  However, the long arrow in what appears to be bolt configuration in line with the piston/rod line.  Here is a puzzling note... in the position you see in the pictures... I have valve lash on both the intake and exhaust.  I think it's at TDC, given the visible crank timing mark and valve lash on both valves. 
      Any thoughts ?  Does this appear to be in proper valve time ?  Have I missed anything simple ?  Thanks in advance for your input.

      While driving the MSU 800, it runs good but it lately it will not go over 20 MPH. The side by side will hesitate when it reaches 21 MPH, but it will run good under 20 MPH. What is the issue?

      Hey guys. I was wondering if anyone pressure washes their Mule underbody. Three years in, I have yet to do this. I'm worried that the pressure washer could damage or dislodge something but it's gotten to the point that it could use a bath. Any thoughts?

      My dad has recently acquired a 2510 Kawasaki mule Diesel powered. It worked fine  few weeks and then quit driving. Put a new belt on just to see. Still not driving. It already had a new clutch. Belt turns when in drive or reverse and back wheels are off ground to test. But wheels not turning. Thoughts?

      Hello, I have a mule 4010 trans that appeared to overheat based on the temperature light on the dash and it went into limp mode.  No steam though.  After letting it cool and the next day, I drove it around quite a bit and it did not have any problems.  Any ideas on this.  Do thermostats work intermittently?  I would like to fix the problem, looking for advice.  Many thanks
