First new to me saw this year ! Mac super 44A

I like that term "Saw Piler Upper" it is a disturbing affliction . Those old DB saws were slow but had a lot of torque I only had a few mcculloch saw over the years but way back I did have 101b mac Kart engines I had them turned way up ran Klotz alcohol/nitro blend racing fuel, ported and 2 carbs on them I have my Kart manual around somewhere I dig it out for a picture JB
