2012 Polaris Sportsman 500 won’t crank over

Hey guys. I’m new to atvs. I have a 2012 Polaris sportsman that I bought brand new. I put quad on trickle charger. It cranks but won’t kick over. I did starter fluid no change. It eventually started but sputtered bad then shut off then went back not kicking over. I don’t know if anyone has run to an issue like this. So anything would help.
