    So I bought a 051 av eq and cleaned it up and it runs. Any reason to modify it? It has a 26" bar. It's way more saw than i need. I usually do muffler mod on my saws but does this saw need it? I haven't cut with it yet. I know these saws will pull a 5 foot bar.

    I really doubt a 90cc saw will pull a 60" bar.
    It would more than likely have a very hard time with a 42" bar.
    Stihl rated it for a 30" bar...
    Just saying.

    Smoothing out the ports and crankcase along with slightly advancing the timing will usually improve performance.

    I don't plan on running a bigger bar anyways or using the saw a ton. It weighs like 30 pounds. I was wondering if it needed modification or gained a great deal of power from some simple mods like some saws do.
