Chain wont turn

[onedash]

My chain jumped off the bar while I was buckin and now when I put it back on it wont turn. There seems to be one or two teeth that just stick in the bar. Another chain works great. It looks normal to my naked eye but it must be slightly bent. I can find the teeth too because once they get stuck it's hard to pull them out of the bar. Is that something that can easily be fixed? It's a stihl chain that is pretty new.

Take the chain off and look at the drivers the are prob bent or marred, put it in a vice and flat file any bugged up areas . Then put the chain back on not adjusted tight but loose and let it break in to fit again.

They may be bent. Lay them on a flat surface. You'll be able to tell. I've had to lightly tap some on the anvil to straighten them out. Double check to make sure there is no burrs on them. If so a file maybe in order. Good luck.

Yup.

inspect your rim/sprocket for excessive wear as well. A damaged chain can cause sprocket damage. A damaged sprocket can also cause chain damage. It’s like a disease that spreads.

Prevention is better than fixing. Chains that are running too loose are more prone to jumping off and you're lucky if there is no damage.

Brush is good at derailing them too especially like you said when loose.

When the chain came off the chain catch in your chip guard booger up the some of the drives. As mentioned above check the drives and flat file any burs.
