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.

I just picked up this project that I was told would crank, but not start. This is what I’ve figured out so far….
I installed a new battery and get all dash lights, head lights, and brake lights on when turning the ignition on. Fuel pump even turns on. It does not crank with the key, but would when I jumped the starter solenoid, so I replaced it…..no change.
Figured I’d check for spark and compression while I was dorking around. Compression is 150 psi, but there is no spark. Replaced the spark plug… no change.
So, is my new starter solenoid bad? Could it be the brake or gear position switches even though the brakes and neutral lights come on? Not sure where to go from here.

I had to remove the relay for the dump bed due to it popping the fuse for main key power. I have tried to find a short but nothing seems to out of normal. I also disconnected the dump motor and switch and still pops the fuse. Also, when the machine is warmed up i get about 5 to 10 of work out of before it stalls. Once I can get it to start again I have to use the choke to keep it running.

I have an Axis 500 4x4 UTV that I was given. It looks like an almost new machine with 39 hrs on it however it was apparently under water from the hurricane . I have no spark at the plug. I have replaced the plug, the plug wire, & the stator so far. Can anyone advise me of what i need to check and or replace to get this thing running? Any advise would be greatly appreciated.
Thank You,
D Maynard

Coleman UT 400 has a strong sulfur/emissions smell from exhaust all the time. Kind of like it’s running rich and a catalytic converter is trying to make it run cleaner so it smells bad. Also misfires when warm. Idles fine. Full throttle fine. In between it cuts out. Do these have catalytic converters? Almost acts like it might be clogged if so.
