    Correct RPMs

    I modded the muffler on the 'ol ms310, and tuned it by ear. A hint of "burble" at WOT and smooth in the cut.
    For chits and giggles, I put the tach on it and it it pulling 13k with bar and chain ( no load). Does this sound right? Has great power in the cut and dosent bog. This thing really screams now with about 10 min worth of work.

    Fastest timed cut is the best setting, but the burble out and smoothness in a cut is good.

    Make mine Stihl, running:
    MS-361 5/8" muff-mod
    MS-660 3/4" muff-mod

    I'm told you can toast your bearings if you run it much past the max rpm, so make sure you don't freewheel that sucker too long. I have the same issue, and my saw "burbles" at about 14,100 and max is supposedly 13,500. I just keep it in the wood and it rarely gets above 13,000.

    If you want to have some fun with your MS310, tune it to about 15.5k and do some CSM-ing with it...
