Why won't my chain spin?

[NCPT]

I put a new woodland pro chain on a 14" bar for my 025. I made sure all the numbers matched when i ordered the chain for the bar. Cut with it yesterday cleaning up some overhanging limbs and small trees around my field edge. Got into one small tree with a heavy lean and ended up throwing the chain. Now I have to force the chains links back into the bar and the saw won't spin the chain. I must have got my specs off but I thought they were right. To be honest, I'm a little confused by 3/8" and 3/8" lp. Any advice/help is appreciated. Thanks.

Check your chain brake. I've accidentally hit it and same thing...

Look at the bottom tangs of your chain, they are likely boogered in spots..

The chain in the pic is a Stihl chain.
Just out of curiosity, put up a pic of the teeth on your sprocket too.

That's the first thing I checked, put another 14" chain on and it spins no problem.

Do I just touch them up with a file of needed?

Yes, I put the green label chain back on that came with the bar to troubleshoot.

Put up some pics of the chain in question, and of the sprocket teeth.

Yes, you can clean them with a file.

It's a brand new 3/8" sprocket.

The drivers are likely buggered up when the chain came off.

I just checked the drive links, they have some spots that need filing. Going to the vise now, I'll report back....thanks.

My guess was boogered tangs too. That's exactly the kind of cutting where you're most apt to throw a chain, and new chains are going to stretch most when you first use them.

Make sure they are flat - any remaining burr is going to eat the bar groove until the burr wears off.

Boogered Tangs? Is that Pooties' brother??

Hit the links with a file.....problem solved and lesson learned. Chain spins freely again. Thanks again.

Here's the pic of the damaged chain and sprocket.

Don't throw out that Stihl chain, it has a lot of life yet to live...

No , Pooties brother is Prune .

Done the same thing cutting some saplings, threw the chain and buggered the drive links, a little filing fixed the chain and was back in business.

That anti kickback stihl chain actually cuts good.
