As long as we are in the McCulloch thread and looking at 1-72's here's mine.

I had to replace the clutch cover and clean it up a bit but other than that it was good to go just as I got it. I really like the unusual roller nose bar on this one.

You're just teasin' because ya know I need one for that sweet PM8200 I snagged last week!!!
19933a - probably a 4-30 but I can't find that part number on the piston list, too cold to go to the shop and look through a bunch of IPL's
46848 +10 - I can't find any 46XXX part numbers for pistons, lots of 48XXX
55310a - 1-71 standard bore, 2.119"
61428 - 450 standard bore, 2.157" - keep this one for me if you don't have any other takers
48852 +20 - can't find this one on the list
53941a - S44A/S55A standard bore, no thrust washers, 2.119" bore
51210b - D-44/55 standard bore, 1.995"
48841 +10 - can't find this one on the list either but 48844 fits several kart engines

That's very interesting and different. I'd be interested in buying that if you decide to sell it one day. Bar and or complete saw. I have a 1-60 that came with a nice solid welded tip roller Mac bar and a new loop of Pro McCulloch 1/2" chain. I like that bar a lot it's different.

My 640 came with a specially modified solid tip bar.

Hello all I am a Mini Mac owner to be, and I have a fuel question. First if there is a better place for me to put this just go ahead and move it I don't want to thread jump anyone?
I just bought 3 saws one old R15 partner , 1 Homelite xl 500 auto , and a Mini Mac . I don't even have them yet but I will by Wednesday evening. According to Acers site the Mini uses 40:1 mix, does that sound correct? The Homelite uses 32:1 and the Partner uses 25:1( prolly to keep the black fly's at bay) I have run old partners in the past on my 50:1 mix that I regularly use but after reading on Acers site it looks like I should have a gallon of all 3 ratios on hand. Is this what you would do,.. or do you run a happy medium of some sort? I will post this is the Homelite sticky as well jus to get some Homelite opinions too. Thanks Jeff

I bleed YELLOW!
I'd pick either 40:1 or 32:1 and use it for all saws. I run 32:1 in all my Macs and my modern back pack husqvarna blower and modern husqvarna trimmer.

My brother came up with this saw and thought I might want it = 0 dollars so far. Acres site says Walbro HDB but there seems to be several HDB carbs for the PM 650, can anyone point me the right direction here?
Try Rockcrusher or customchainsawparts, either one will have carburetors that will work.
Perhaps one of the sponsors like chainsawr as well.

Back in the early 60s, when the roller nose bars started being popular, most of them were made from existing hard nose bars. In those days there were a lot of shops that did bar repairs and modifications. Even the factory took hard nose bars off the line to make roller nose to meet the demand.
Fallers liked the roller nose bars because you could run the chain tighter, chains didn't come off as often, and fewer breaks. Roller nose was susceptible to being tweaked when limbing.
Hard nose bars stayed around for work on landings and dirty areas. The bearings wore out pretty fast in the dirt and greasing them only made it worse
It only take a twig in the right (or wrong) spot to jam the chain on most roller nose bars. Nice to look at, nice for show, good for racing in cants, but not a great all day every day solution to fighting friction at the nose.

Too me awhile to find my pics. I got lucky and got this bar on a 1-60 I bought. Chain is 1/2" McCulloch Pro chipper was like new. I really liked the bar it had so it was a good buy. Only other one I seen is the one you have...

I've been fooling around with a D44 the past week between back spasms, but put it away for a while waiting for a carb kit.
I drug the 797 out and decided to see if I could figure out how to square file a chisel bit chain. I've never filed, seen filed, or used square chisel chain before, so had to figure out how to replicate the grind on old chain.
The first cut went pretty good, but saw didn't seem quite right, I realized I hadn't closed the compression release. The next cut went even better.
The log was a standing dead western hemlock I cut a couple of years ago. It's hardness is rated with doug fir, but this log has a lot of water in it and has been frozen to 10deg for the last two months( I know, that doesn't seem so cold to you southern boys, but this is Alaska, not Wisconsin or Minnesota ). It was getting dark by the time I got outside to make the cuts so they don't show too good. I'll try to get out today and make some cuts in the daylight.

Nice haul, Mark. If you don't have plans for that PM850, I might. Ron
