That's a nice saw you done good right there!!!! Personally I would have put new seals in it when you had it apart and a new o-ring on the oil pump housing.....cheap insurance for such a nice example. That's a sweet bar.....but IMHO way to much for a 70cc saw.......You need to cut 32" a lot you need to be in the 90cc area....or more. As far as saw handling.....this entire saw family absolutely handles best with an 18" bar......now I know that sounds like blasphemy to a lot of folks, especially out westers...but it's true......if you want a saw you can fell and then limb with....and I mean with very good handling, so as not wear yourself out working all day, 18" is the very best. I have some of these saws with 18" ...most with 20" and some with 24". Will the 272XP run a 32"? Sure.......as long as you don't lean on it to hard.... but it's not likely to your go to saw with that set up. Wicked nice saw though!! Congrats!!!!
