I've got a 14 sportsman 570 and when I go to start it, it cranks for a second, stops, then cranks and starts (not letting off the key at all). Sometimes the time between the first crank and when it starts cranking again is long and sometimes there is barely any time in between at all. It's done this forever but just wondering if it's supposed to do this? Never had any issues not starting. My 800 doesn't do this.
