chainsaw chain and sprocket won't turn

I bought a reconditioned Husky saw a couple months ago, and several times the chain has stopped spinning because a wood chip gets stuck in the chain and bar and I unscrew the two screws, take off the cover, clean it out and chain spins fine again.

Today chain stopped spinning so I undid the two screws and took the cover off and the sprocket behind the back end of the bar won't turn. I'm new to chainsaws, but I assume that the sprocket is supposed to turn and has somehow seized up? Right now bar and chain are off the saw and the sprocket still won't turn.

What are the possible problems? Thanks for any advice.

Will the sprocket turn when you crank the engine over? If so, the bearing/bushing the sprocket turns on is seized or there is a problem in the clutch. My best guess without looking at it.

problem solved

Mike, thanks for reply.

However, i found the solution and it was a naive mistake: the chain brake had somehow got engaged. I was taking things apart and cleaning to get a better look and could see a band around the sprocket assembly and the band leading towards the chain brake, and then it clicked that there was this thing called a chain brake.

I'm pretty new to sawing and I've never quite known what the chain brake was and why it's there (I understand it's a safety thing and stops the chain, but I don't quite understand when it would engage and keep you safe).

Glad it wasn't serious. I didn't think about the chain brake. My old saw is pre-big brother. I get so tired of gov't. and lawyers treating us all like we are total idiots. I better stop before I get a rant started.
Glad to help,
Mike
