that is what happens when my stupid brother ran a bad mixture through our grandpas saw so long ago. it sounds so nice. i was amazed that after all this time it fired up! took some pulling though to get the cobwebs out!
for adjusting the carb when it is idling high what screws have to be adjusted?
Adjusting the needles is not my strong suit but here goes: The idle should be set so the chain stops moving when at idle. The low speed needle is set so that it revs up snappy when you hit the throttle. The high speed idle is then set rich enough so the saw sounds like it is four stroking when not in the cut and when you start cutting (under load) it should sound two stroke and have lots of power. If you are too lean on the high speed needle it will have high RPMs when not cutting but no power in the cut. In short set the high speed needle for max power when cutting with a four stroke sound when not in the cut.
Clear as mud...
