I have discovered that a Husqvarna 266 starter pulley can be used as a substitute for the pulley on a Poulan 3450 and related saws. All you need to do is turn down the axle spindle on the recoil housing and grind the Husqvarna pulley hub notches about 3mm deeper. I didn't get to give it a long-term use test before sending it off, but I was so delighted I cranked it over and over again, at least a few dozens of times without a hitch. I plan to do it again on a keeper.
