2013 800s rzr misses at low speed

No on the timing..sounds like the carb needs a professional cleaning.. and replace the spark plug!!

Not for sure, but if you belt is hot and you put it in H for HIGH then the gear multiplication may be such that it slips and won't pull because the gear is too high. By putting it in R for Reverse or L for Low you will get a lower gear ratio and it might pull the Rzr even though it is slipping. I would check the belt and the primary and secondary clutch adjustments.

are you using the correct key --possible need tune up --check fuel filter air filter plug and wires and possible carb / rebuild

Check to see that the pinion gear of the starter is hooting out and engaging the flywheel.
And if it is working it is possible that you have missing tooth/teeth on your flywheel and the starter cannot turn over the engine because of that.
