Poulan PP4620AVX with revolutionary no tool plastic tension adjusment.
Recently, well Apr. 2011, but first real use now, purchased a Poulan PP4620AVX. Plastic no tool chain adjuster is in plain English "crap". Poulan should send everyone the old clutch cover chain break, part #530054819! Seems everyone is having trouble with chain tension and I believe it's because of this new set up. You need the 2 bolts to hold the bar in place and a solid screw to keep the chain tight, not a plastic cheapy.

Incidentally can someone tell me where to find the serial number? I called Poulan and the person on the phone didn't even know and couldn't help me with my request for a replacement part for this problem. I should not have to pay!
