vintage saw score

[Pablo26]

I was just about to complain about the lack of old and used saws in these city parts, when I roll into a garage sale on my bike this am to find this saw, which is from my local saw shop no less. Started on one pull, seemed to idle and rev fine, owner says it leaks a little bar oil, boo-hoo. He wanted $5.00 for it, good thing I had $6 in my pocket. Here it is after a quick bath. (see attached photo).

That saw is definitely going to warm you twice! I've always been nervous using a saw without a chain brake after reading all the talk about serious kick-back.

I have an old 610 clone (Eager Beaver 3.7). It's kind of interesting, because the 610 cranks very reliably, I've used it since 1987 without an service, and have only had to replace the recoil mechanism, the bar, and the on/off switch. It leaks bar oil after using it, but I still use every once in a while.

Mine has the sprocket rim set-up, which surprised me for a saw bought at Home Depot. I think this marked the demise of the brand as they failed to modernize and use lighter materials, address fuel economy, and increase the power per cc. I've gone modern using Huskies and am always amazed at how fast the fuel burns on the old Mac.

I hate Mac didn't stay in the chase. I would love to see a premium USA saw. I don't think we can cop out and say we couldn't compete on labor but I don't think Sweden and Germany can even compete with USA labor rates!

I pulled a new loop of Carlton full chisel out of of the cubbord and it was a perfect match. Air filter washed and dried. Fresh mix in the tank. Sure has a nice exhaust note to it, and tangy vibes to boot. I'm not sure I'm getting enough bar oil, manual plunger of course. Back out to check that out. Logs may have to wait till tomorrow. Thanks for listening, we're a sick group and most normal folk just don't understand.

No doubt the old Mac's sound good echoing through the woods.

Yup this has a rim sprocket set up set up too. I'm sure the folks down at my saw shop will get a kick out of it when I bring it in with their sticker still on it.
I sure won't need to do any serious wood cutting with it, but will be fun run. Will definitely strap on the helmet, chaps, etc.

Yes it does indeed have a manual oiler.However,hidden in the oil tank lies the best auto oiler ever made.An impulse driven piston oil pump.To get to it,just remove the screw holding the front of the tank on.Clockwise on the adjustment screw decreases the oilflow and visa versa.

What the screw does is to increase or decrease the piston stroke.An old Mac trick,run a tank of diesel fuel through the oiling system,works wonders most of the time.

That saw,by the way,is the largest of the 10 series saws,unless you include the sp81,800 etc.Properly tuned it will hang in there with the best of them,old or new in the 70 cc range.Loud and no anti vib but still a good old saw.If you are concerned about the lack of a chain brake,about any 10 series ,left hand start chain brake cover will fit,e-bay,cheap.

Nice score fer 5beans! You'll probably want a pair of gel-pac gloves and some sort of cushy rubber bar wrapping iffin you're going to use it for more than 10mins! Is it actually strickly manual oiling or is that pump extra like on many of the old Homies? Just curious. NM, Al Smith just answered that Q, thought so, cool!

The shake rattle and roll thing,I've never figured out.I have a bunch of 10 series saws.Some will make your fingers go numb,some not.

I like several others hated to see the demise of big Mac.The 10 series saws at one time were the bench mark of design.Perhaps if further development were given to this series,and the board of directors at McCulloch motors weren't asleep at the switch,things would have been different or perhaps not.We may talk about but it we certainly can't change it.

Wow, thanks for the feedback on this saw, sounds like I have a classic!
The oil does work, but will try and turn it up a bit. Here are a few test noodles from the back yard
