Well I just found this thread and just recently entered the 2-man club. I had posted this in the Mcculloch thread.
My brother called from a local auction telling me about a 2-man saw. Honestly, I wasn't too interested until I saw the photo.
Mac 7-55, 161cc. Wound up getting it for a song. Did a teardown and clean up but only repainted the transmission, stinger, starter cover and frame. P&C look like new. The bar on it will do a 38" cut. Even got an extra bar (48") but no chain. It takes 3/4 x .077.
I learned something watching American Restoration. Best way to clean up old rubber is glass bead. Did it on the grips and they look like new. I put a coat of clear poly on the two outer grips.
I had to weld up a center section on the muffler and sharpen the chain (5/16" file). Checked the carb diaphragm and cleaned the fuel bowl. The saw had been put away right - no old gas but I doubt if the fuel bowl had ever been off before. A few pulls and it started right up. Planning to take it to the Western PA gtg next week and hope to get some vids in some big wood.
Might be nice to have some dawgs for it.
