It could work but the 262 pulley is smaller in every dimension than the ones for the 266, (and the 268, 272 and 61) which are close to the Poulan in overall height, 38mm, and outside diameter of the hub, 24.5. The ID of the 262 pulley is 12mm, the Poulan ID is 18 and the 266 is 14, so the 266 let me preserve more meat. Also, generic pulleys for the 61 are cheap.
