    Two questions

    1. I have a Stihl MS 441C with a 20" bar. I'd like to upgrade it pretty substantially. From my reading here, it seems like the best things to do are

    a. Drill muffler
    b. Re-tune carb
    c. Add high flow oiler or else mod oiler to flow better
    d. Upgrade dogs
    e. Buy a 25 or 28" bar

    What do y'all think, and, could you possibly point me to specifics on precisely how to do these things? Or, in the alternative, do y'all know anyone I can ship this thing to to get this done? I don't trust my locals.

    2. I have a Stihl 310 with 20" bar. It runs like crap, but I think it's because my bar is toast, specifically I think the tip sprocket or whatever you call it is bad.

    It spins all right, but it seems like the teeth of the sprocket are too worn down, and I think the sprocket may be bent to one side. As a result, I never get a good chain roll. I've attached pictures.

    ---
    Thank y'all. I'm a complete novice, so feel free to tell me everything I've done wrong and how bad my ideas are!

    You should post this in the chainsaw forum if you'd like more response.

    441R Oiler and a 25” bar is good combo
    28” go with a 460R Oiler or 660 with a 28”
    It will pull both fine with a muffler mod

    Yup, yup - I looked for that and missed it the first time, thank you. Reposting now.
