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 have a bulldog i bought from home depot in 2013. In the last season it started refusing to shift from neutral to either forward or reverse. I changed the trans axle fluid and made sure the cables were lubricated and free. With a lot of coaxing, I can sometimes get it to shift. once I start driving it, things improve until I let it set awhile. Any suggestion on where to go from here?

2013 Bennche Bighorn 700 EFI
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.

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?
