Those are OLD pics of my 35A. That bar and chain now reside in RandyMac's stable. The red paint is something someone brushed on decades ago. Most of it comes off with a fingernail. It 'sort of' runs, as the carb diaphragm is sad. Has good compression. The tank bottom is extremely corroded, and was patched decades ago with some kind of brown epoxy putty. It weeps...
I have a 35 that came with a nice (but short) 'oval McCulloch emblem' bar and a loop of 1/2" chain. The tank bottom and other parts are good. The saw feels 'crunchy' when turned over. Probably rusty bearings. Somebody sprayed a pale yellow over the saw to make it look better. I was told that it ran not long ago...
Between the two saws, and possibly with the addition of an NOS carb diaphragm (if the one in the 35 isn't good) a person will have a runner. That person won't be me however, as I'm gonna send the whole shebang to Brian13. He has more patience than I do, and is still lacking in the McCulloch gear drive department.
