This ATV has for last 2 years started almost instantly, about 3months ago - it would not start up (turns over great). Few days later it starts and runs fine- started several times in couple hours I rode it. Tried next morning- would not run! Tried to start several times in next week- no run. It decided to run after sitting few weeks- ran fine for about 1.5 hours. It sat for couple hours and hasn’t ran since! each time it would not start- I had no spark. It seems to decide when it wants to fire. I have changed plug and checked pick up.
sorry about long story.
thanks in advance for any leads
