1999 Polaris Sportsman. I just replaced the starter and the plug about 4 months ago. I havent driven it much at all put just pulling a trailer around the yard and an occasional run up and down to wear the dog out. Anyways, the atv wont start now. When I it the starter, it will turn over for 1/2 a second then just make a winning noise like the starter is hitting put nothing is turning over?? Any thoughts on this. Im tempted to take it up to the stealership but its 15yrs old and I dont want to put more money than its worth into it. Anything would be helpful. Pull start wont start engine either!
