I may have created a monster! I recently sold that MS460 we resuscitated to my next door neighbor Chris, and I put a 20" bar on it with some square file chain so he could try it out this past weekend (he went upstate).
In addition to replacing the broken clutch, we also put a dp muff cover on it and HD-2 filter, removed the carb limiters and tuned it right.
Well, he is ga ga over how the saw ran, and wants me to teach him how to file square file chain!!!!! Even though he has a 441 and 10mm 044, he says this is now his primary saw. I guess when you are 6'6" / 350 lbs, and additional fraction of a pound does not bother you a bit!
He said the saw ran super strong, and the square file just went through everything like nothing! It is good to have Happy Campers!
