Can't solve this. Cany anyone add any light or similar issue? Rebuilt a 365 that had been crawled over by a tracked chipper. Included new bearing seals as split crank to replace clutch side. Ok. all back together with new rear handle to boot (non OEM but it seems reasonably rugged). Fired it up but chain is turning over with every pull. It ticks over and idle and Low adjust as they should hence discounted leak around new seals yet chain is turning no matter what. Looked a little deeper thought clutch was shot thus engaging with every pull, but springs not that weak. Pulled apart clutch side, I discover clutch appears to be binding with oiler (this after looking without sprocket on). The order things are reassembled according to diagrams are (thin washer) before oiler (so this sits virtually next to bearing seal) then oiler torx screwed down, then clutch directly on top (reverse thread). But even if i sit clutch only lightly tightened on it still binds with and turns oiler. This obviously then turns sprocket and hence chain. I prob should post pictures but there are so few parts involved, I cant seem to seat clutch without it tightening on to oiler and spinning it, there's plenty of play elsewhere and am used to tightening clutch down reasonably firmly and not catching on other models? even with a thin washer inserted in there its still going to pick the oiler up. Driving me mad, am wondering if crank has been bent (even only a microscopic amount) encouraging the clutch to bind? arghh Any ideas?

Hi everyone. This is my first post here. I'm a landscaper who uses his chainsaw rarely. So rarely in fact, I only have an electric chainsaw. Yes, I said the word that's probably banned here. I only use it for small parts of my job. For real tree work, I call my tree surgeon! It's a Black & Decker GK2240T. ANYWAY. I hit a nail in an old fence post I was chopping last week, the saw jammed nicely, so I presumed I'd find bits of nail under the cover and the chain to be all mangled. But it wasn't. Everything seemed fine. I took the chain off, gave everything a clean. But now the chain won't turn. The throttle works fine. The drive sprocket spins freely when no chain is attached. And it actually drives the chain when it's really loose. But as soon as I tighten it to how it should be, I can't even move the chain along by hand. And when throttling, the motor will run, but it won't engage the drive sprocket enough to turn the chain. I've looked at the bar, and it doesn't appear bent (by eye). The nose sprocket turns freely. I've cleaned out the groove in the bar, and it doesn't look pinched anywhere. The chain doesn't look visibly damaged as far as I can see (but besides the blades being blunt etc I don't really know what to look for) Any advice? If I can't move the chain by hand when tight, does that say something obvious? Do I need a new chain? New bar? Any help would be much appreciated. And I know that by default, having an electric saw makes me a bit of a joke here, but I humbly and honestly look up to you guys for your expertise. Thanks in advance. Jon
