I have a 2013 outlaw 50 i purchased for my son, the atv has ran fine until recently and was used frequently. Now when you try to start it all is does is spin over and never fires, you have to continue and continue and clean the plug a couple times and fires and runs fine afterwords, and during that period you can turn it off/on and it starts back fine. Then when you let it sit overnight and go to crank it the next day you experience the same issue of taking the plug out and cranking and cranking on it. I have cleaned the carb jets look good, changed plugs, i am getting spark but ongoing issues, any suggestions or anyone had this problem, any thoughts??? issues with valves sticking? not enough fire?
