you might have a broken shift dog. try disconnecting the shift linkages and turning them with pliers first to see if shifter is out of adjustment first.

Check the electrical connectors especially at the ECM.

I did it on a 300 and dont recall it being dificult, just a bolt holding it I think?

Somewhere you have a bad connection. Trace the power line with a test light and find where you loose the current.

Check your fuses

Disconnect the pipe from the manifold. Take off the brackets and move the pipe backward far enough to remove and install a new donut.

check conections on new parts just had that deal new cdi had one wire that pushed out just enough to lose contact. sounds strange but it happens.

It may be a full time 4x4 therefor it does not have a lever to shift

Make sure your fuel system is clean.

Sounds like it is running lean. Adjust the air fuel mixture. If that does not help, may need to do some carb work.

Could be the coil pack going bad or fuel pump. Find the coil pack and spray water on the outside of it. Not a lot just a stream to keep it cool. It should be on top. Here is a video https://www.youtube.com/watch?v=woE4OIhCvAs

All most positive it is in your carb take the bowl off it as you take it off there is a small tube that hangs down that all most reaches the bottom of the bowl need to take a small wire and push through it it is blocked .symptoms backfiring no idle coughing and sputtering if it does start

Check the drive belt and assembly

Sounds like one of the wires on the loom might have come undone, just run through the loom, especially all the wires to the ignition.If that fails, looking at the model, could potentially be a CDI failure. Good luck

you can pull the oil tube off the carb for a couple seconds while its running to see if it drips oil. I'd run a synthetic 2 stroke oil, lubes better and burns cleaner.

If you are certain the spark plug(s) is in good condition and correctly gapped, and the magneto is working normally, then you may have a fuel system problem. A quick diagnosis of fuel system issues is to spray a shot of starter fluid or WD-40 into the intake through the throttle body. If the engine fires for a bit then quits, it's a fuel system issue. Small engines do not do well with old ethanol-containing fuel. If it's turned yellow, drain it out and replace it, and remove any in the carburetor float bowl also. Air leaks in the carburetor or intake manifold gasket may also cause hard starting. A sticky carburetor float or float valve is another possibility, especially if the engine was sitting for a long time with ethanol fuel drying out in the float bowl. A dirty air filter will also cause starting issues.

Based on information provided I would start with just checking the basics as far as servicing goes, starting with air filter, is it clean, and is there anything preventing it from breathing easily. Check the accelerator cabling, might be dry, stuck or mucky somewhere from pedal to carburetor that can cause similar problems. Check oil level of motor as well.. Hope this helps
