I started having a problem with my starter clutch recently. engine is a 163FML 2007 SunL atv.

My atv would not start after i shut it off the other day. the starter just spun. i push started it and drove home.

after cool down, the starter would still just spin. didnt turn the engine over.

I pulled the flywheel cover to see what the problem was. I noticed that the starter clutch(sprag clutch) was spinning freely in both directions.... it only supposed to go one way.

i used my impact wrench to remove the flywheel bolt. when i did, i noticed that the sprag clutch was now working perfectly! yay! i thought maybe something got stuck in it and the impact got it loose.

i put the quad back together and drove it the next day. the starter was working great. after getting home and shutting the atv off, i tried to restart it. the starter just spun.... i removed only the flywheel nut cover and used my impact on the bolt for 1 second. then it worked like it should again and the starter engaged.

has anyone experienced this issue? how hard is it to replace the flywheel and or start sprag clutch?

below are pictures and videos
the initial problem

after i impacted the flywheel bolt it was normal

This bolt was very tight. I used my impact to loosen it and remove it. Then re-installed . I did not remove the Flywheel
