So recently I popped the cover back off and backed the oil adjustment screw out some. Now I'm getting more oil to the bar, but not too much. Maybe not enough. Not sure how to tell, but I can see a little lubrication between the chain and guide. I pump it occassionally to give it more.

I got a new chain and it cuts like a dream. I am having an issue with keeping the chain taught. If I make it too tight, the saw binds up and can't spin it fast enough. But if I make it just right, it'll loosen up to the point where the chain droops. It stops cutting too when it's loose like that. I tightened the crap out of those nuts to the point where I think I'm about to strip them. Is something worn out that should help keep this bar from moving?

Yeah it needs to be flying off the bar a bit or over half empty at fill up time but you'll get the feel of it.

I suspect the drive sprocket is probably toasted and not meshing well with a new chain
