thanks, it says 20-1 ratio? what do you guys think about that?
Woody - If you find a D-39 please let me know, I have the D-30 and D-36 already but could use a D-39 and the very mysterious D-45.
Leo - 40:1 with a good mix oil will be just fine. The 2-10 is probably equipped with the little flat back A.K.A. bullfrog carburetor. Be prepared to study and learn a bit as that one will be unlike anything youv'e worked with before. I think you will be happy with a 16" bar on that saw, it might be able to pull a longer bar but maybe not with the authority you would like. Many of the original saws would have been equipped with a McCulloch unique .354 pitch chain, sort of half way between .325 and 3/8.

Is the D-39 rare?I don't know what to offer him for it.I keep asking him every time I stop by if he wants to sell it but he keeps saying no.It just sits there on the shelf collecting dust:bang:It turns over nice and seems to be complete.He does have what looks like a D-39 saw and trimmer/brush saw both bought at the same time he got from a neighbor.He did sell me a nice Husky 44 that was in his back room for a long time full of dust that needed a coil this last summer.That one I will finish tomorrow.I might go over there Mon. and get some pics and ask again.
What are your opinions on switching my 7-10 over to an 8-pin rim? This afternoon I finally got a chance to bury the 20" bar and it laughed at my feeble attempts to try and bog it down. This was in seasoned mesquite too -- probably the hardest wood available around here. It was actually pretty damn impressive. But it got me thinking: if this saw has that sort of torque available I could go to an 8-pin and gain some extra chain speed -- since most of the time this saw would be used for 8-18" oak I think it might be a worthwhile consideration?
Can you get an 8 tooth rim to fit the stock 10-series saws or does the whole drum with splines have to be changed? I inquired about them once from a supplier and was told that the drum would have to be changed to a larger size spline. I've considered putting one on an 850.

Why keep bothering him if he doesn't want to sell it? He knows you want it so I'd just not bother him any more. I'm sure if he ever wants to sell it he'll remember you asking.
I agree. If you keep pestering him he will label you a pest and not sell it to you, ever, at any price, on principle.
In fact, if you don't ask him about the saw he may get scared that you don't want the saw anymore, and offer it to you.
I picked up a new project yesterday. It's not exactly yellow, but I figured that since it is sort of international related that it might be O.K. with a few of you.

There is some confusion up there guys, the 10 and 600 Series drums (they are identical) are available with spur type sprockets (7T .404) and both large and small spline. There should be .325 sprockets available in the small spline (7 and 8 tooth) and large spline (8 and 9 tooth) so it would be easy enough to set one up with .325 9 tooth if you just get the right components. In fact, I think that is how one of my Titan 57's are set up right now, one with 18" 3/8 and 7 tooth and one with 18" .325 9 tooth.
I expect there are probably 7T 3/8 as well but I don't remember having any; I do have the other three on hand so I know they exist.

all these following saws are 10-series: my 54cc, 57cc, and 60cc Macs are 7 tooth 3/8 with small spline. my 70cc and 82cc are large spline 8 tooth 3/8 with exception of the PM800 which is a 7 tooth since it usually wears a 28" or 32" bar. all my 600 series have 3/8
7 tooth in either small spline with rims or spur type.
i have aquired about two years ago a mcculloch 24" with a replaceable tip. the previous owner replaced the tip with a .325 pitch and i've never used it. after hearing this talk here, i could set up a saw with a 9 tooth rim. now the question is, which Mac would be the most impressive with a 24" bar and a .325 chain and 9 tooth rim??
Well, the biggest according to me. In harder wood, burying 24" .325 to my idea would take at least 70 cc. I do have a 56cc set up with 7T .325 with a 20", and it likes that Ok. I think it may bog a bit with an eight pin, and wouldn't dream of a 9T with that one.
In soft wood it may well shine on the 60cc. Especially if its in .050, at the most .058. I feel if you want to run .325 in .063, you may as well run 3/8 in .050. Your experience may vary, try it and let us know.
