Poulan Pro 20" problem tightening chain

I purchased a reconditioned Poulan Pro 20" 50cc chainsaw and it arrived an hour ago.
I assembled it (bar and chain) and it seemed ok.

I cut for about 1/2 hour and stopped to tighten the chain. Since it was a brand new chain I knew it would stretch a little right off the bat.

Well I tightened it as far as the adjustment would go and the chain is still hanging off the bar. There is no more adjustment left on the screw, it is hitting the frame.

Since the saw and chain are both only a few hours old, I have to determine if this is just a bad chain or if the saw is so poorly designed that you can only get 1/2 hour out of a chain, in which case I will just return it. This is my first poulan pro (in the past I have had wildcat and Remington).

Does anyone have any experience with a poulan pro that would lead them to think that a new chain will fix my problem?

Somebody installed the wrong chain, it was likely near the adjustment limit. The quickest solution would be to have a local saw shop shorten it by one maybe two drive links.

Source of the problem could be someone grabbing a 72 DL chain for it and tossing it in the box, instead of the 70 DL chain that fits its bar. I know something about this, having a PP5020 and spinning chains for it. 3/8 pitch, .050" ga. BTW. And I'm assuming it has an OEM bar.

I'd pull the chain and count the drive links. If there are 72, you can see if a local shop can take a few links out, or obtain a 70 DL chain. Of course, also make some noise to the vendor.

That mismatch of chain driver counts happens more often than one would think .People have gotten used to the more common chain lengths such as Husqvarna and Stihl that use 72 drivers on a 20" loop but fail to realize some brands such as Poulan and McCulloch use 70 .

In my case often I grab the wrong one from my stash of chains hanging on nails in my garage .

My stash of chains is now up to around 200 plus chains.
I gotta stop going to the junkyard.
When a chainsaw dies the owners don't take off the new chains.

Just a few weeks ago I found about 50 harvester chains that looked like new.
I got 6 good 36" bars with them. Going to make a chop saw out of them.
Now if I could just find a good sprocket.
