Nice saw Chris - nothing like a big old Mac geardrive to spice things up in here again.

Regards,

Chris.
 
Here's a pic I dug up of some OLD 7.3ci muscle.

Here's a pic with little Rachel sitting between the smallest and largest saws I had at the time. Poulan XX/Craftsman 1.9 (with 1/4" chain) and Mark's McCulloch 77 (with 5/8" chain). I took the bar off of the 77 so both powerheads, the sprout, and the bars and chains could all be together. Also visible is the rotted muffler Mark replaced, and the large mud dauber nest that was inside said muffler. Thank GOD the piston had closed off the cylinder while the saw was sitting. That kept the little bastards from building a nest in the jug. The 77 powerhead weighed more than the kid at the time. Probably weighed more than her AND the little Craftsman/Poulan together. Check out Mark's thread on the 77, as well as the Baraboo GTG thread for info, pics and VIDEO of that monster saw.

Aaron, how are those 77's to work on? The shop I deal with has a pile of them, and they've always caught my interest. -Sam

They have a PILE of them?????:msp_scared:


Are you sure they're 77's (or 73's) Sam? Those were the 7.3ci/120cc McMonsters of old. Most of the time, McCullochs you'll find that look similar to this saw are a 47 or 4-30. Common stuff. If there's a 49 at your shop (smaller displacement version of a 77), MAKE SURE you hook Mark up with it. He needs one to complete his collection of these saws IIRC. If there are multiple's of that model, I immagine he'd want 'em all to piece a runner togetether. I think he has a 73, but I don't know how complete it is.

They're actually not hard to work on. The hard part is finding carb diaphragms for them. See Mark's thread on these saws. Grab one (or more) if you're up for a bit of a challenge. There were NOS rings, a conrod, and a crank on feebay a while ago, as were a couple diaphragms. The 77 takes the common large-Mac air filter (250, etc), while the 73 has an oddball filter. These saws have the most fantastic castings that I've ever seen in a saw. An exercise in well executed over-engineering. The 'carburetor system' wouldn't fit in a shoebox if you took it all apart. There's a reason why these saws cost $500 in 1957. That's something like $4000 in today's funny-money...:laugh:
