    have you ever run your ported saw in the forest cutting firewood or is it build for fun?
    Or tweeked saw in the woods?

    Without porting, add a larger rim like one or two pins depending on what cc your saw is. A rim and drum is less friction. Plug the governor, advance the timing a tad. If you don’t want to port it.

    On my old 70’s husky 240sg I put a 9 pin rim, plugged the governor.
    On my 266se husky I put a 8 pin rim and plugged the governor.
    On my 2100 added a 8 tooth rim, plugged the governor, advanced the timing a tad.

    How the chain is filed matters you must be a perfectionist with sharpening the chain. Open up the gullet.


    Speed cutting at the local fairs we used every trick in the book setting up the saws. In between the local fairs I would change the saw back to cut firewood. One year I didn’t change it back. My saws were eating wood.

    I've yet to build a saw that wasn't for production work etc etc. From what I see in the porting world the majority of builders just do work saws and maybe build a race saw for themselves just for fun.

    As far as mods, nothing will compare to machining and porting a saw. I don't care for rims bigger than 7 teeth because I just don't see the gains. Maybe if you had a big saw with a tiny bar sure..

    How good at sharpening a chain you are plays a huge factor. Wood type, saw size, bar size, chain size, chain sequence, round or square are all big factors.

    Wood type, bar length/saw size is directed mostly at raker depth.

    In the carb on the older husky saws there’s a over speed governor under the brass screw. We used a hole puncher to make the plugs. Today’s gas I’d use metal from a beer can.

    Unlimited module and turn high and low needles. Saws cut faster right before they blow.;):yes:

    As soon as you adjust the high needle too lean she seezes not a good sound to hear. Use a tach.
