Maybe try pulling the starter cover off again and really inspect the pulley for play or wobble. ...put a little pressure on it and then pull it to see what happens. ...While the cover is off check the pawls on the flywheel for proper movement as well. ...

May or may not have anything to do with your problem however, I had an old Roper/Craftsman 3.7 come in that was doing the same thing. Just as you said starter worked great off the saw and saw turned easily without starter.

Turned out that the back of the starter pulley had a hairline crack in the back, which would not force the starter cord to wind up on top of itself between the sides of the pulley. Cord would wind up parallel to itself, forcing the pulley sides to flair out and bind against the starter housing, locking the saw up tight! Not immediately evident that the pulley was damaged because the crack was right at the hub and on the side facing away from the saw. And this was a pot metal pulley not plastic, when it would lock up it was metal against metal and there was no way to pull the saw over it would just stop dead!

Installed new pulley, big PITA on this saw, everything worked fine with new pulley installed.

I had the samething happen with a plastic pulley on a Poulan Pro 375.  The rope would double up and bind under strain given the space that the hair line ccrack opened up. May have to pull it completely out of the starter housing to see it.

Be careful removing the pulley, the rewind spring can jump out and run all over the shop, as well as hit you in the face causing great harm. If it does jump out also be careful replacing it because it can jump out during the installation process and cut your fingers and hands!

In my case I had bought a spare saw for parts off ebay a long time ago.  It's an old saw.  So yes to new part.

Just take the tension off of the pulley by unlooping the rope and let the spring tension ease off, then unhook the clip over the axis and pawl, and inspect.

I looked and inspected and finally gave up and took it to the shop, the guy doesn't know for sure either and I told him what I learned here.  He is swamped so it might be a couple of days before he looks at it.
