When I start it, it makes a knock sound (spinning sound). While idling or running nothing. Runs good. When I shut it off once again, a knock sound before its off. What gives? Daughter did just roll it down a hill (ER visit required). Is it the starter?

It's the starter one way bearing (starter clutch). When they start to wear out they will make a clunk clunk clunk sound when you start it, and then another clunk when you turn it off. It's not a big deal, it happens with most warriors. Sometimes they will go for 10 years making that noise and never have a problem, but mine started slipping and falling apart about a year after it made that sound. Just keep an eye on the oil filter for metal shavings from the bearing coming apart, and keep in mind that you may have to replace it eventually. Something that accelerates their wear dramatically is transporting them in gear when they're in the back of a truck or on a trailer, I didn't know that was harmful when I got mine, and I think transporting in gear is what tore mine up so quick.

 

Thanks for help! That's it I bet. When we first got it, there was metal in the filter. How much should one run? Where is the best deal. Again, thanks!

 

The parts will run around $200 most places, you will need the starter one-way, and the gear that it mates to. To install it you will also need a flywheel puller.

 

I ordered the starter. It was $180. Didn't order the gear. I need that too? I just pulled it out. No starter gear puller or anything.

 

I didn't install my starter clutch myself, but from what I understood the mating surface the clutch grips on is part of a gear, and that gear can get worn and pitted. I'd replace that gear, leaving the old one in could wear out the new clutch right away.
