The 346 is much stronger than a 242,i try both.Better throttle response and higher rpm,better torque also.I dont think the 242 turns 15,maybe im wrong,probably more around close to 13.PWB said:How's the 346 compared to the old 242 (xp?) had one of those years ago at work (stolen along with ten other saws) and thought it was the fastest little saw I'd run. suppoesed to be set at 16,500 if I remember right! I was too chicken, we ran it at 15,500.
