This just might be the next one to go. Poulan 445 71cc 50mm quad port. I put it back to half wrap yesterday. IMHO best of the series. Seems the hardest to find and get info on. I have 4 of them. 2 runners, 2 with bad cranks I use for parts. 4 cylinders though. 2 on saws.
On the clutch cover inner. It is missing the rubber deflector. Someone over the years had thrown a chain and it must of took it out along with part of the grooving.
