I sold my ms460 and am about to purchase a new ms461r. I also have a 026 pro that is in good shape and was thinking of selling. The saw owes me nothing 20 years of sporadic use and it runs like a champ just wanting something new. Reading posts here got me wondering about having the o26 ported, would it make much difference? What will it do to reliability? Or should I be looking at a 261 or something from the dark side? Any thoughts appreciated.
