Sdc44 is nice too
Does she have a sister?Wife isn't even bothered about it lol.
Jethro, I'll definitely try that before abandoning the Tilly - I don't like being defeated...Really like the 37A seems to just have a crispness to it over the other common 65. Not sure why maybe someone does but that's my 2cents. In saying that my 7-10 with the fixed tilly runs real good too. Just tweak the low as lean as it will take n should help a little.
the 37A are the ones I like to mod for the 125s They do a fine job on the big boys.Yes i have jethro. Used a couple of them before and they were both very touchy in my opinion. I do have 1 currently on a pro 10-10 automatic. It seems to be pretty good. It will stay there. The other 2 are in a box. Yes i rebuilt them and tried everything i could think of but i just did not care for them. Not saying they are bad designs, just not my favorites. I agree also that the 37 and 44 are great carburetors to swap onto about any mac. They did things right there.
Wait your not going to run it??Here she is the way she will be displayed. The NOS NIB SP 125c came to me in that box with everything but the NOS bar. "I added the bar to the package". One day when I am gone someone will get a chance at a true piece of NOS American Muscle Saw History...

I turned it over, does that count? lolWait your not going to run it??
INCREDIBLE!!!!!!!!!!So I did a thing... Yes it is NOS...View attachment 1183667View attachment 1183670View attachment 1183673View attachment 1183674View attachment 1183675
So glad for you!!I saw it, thought let it go, then I thought when or where will I ever get a chance at a NOS 125c again? So I pulled the trigger. Wife isn't even bothered about it lol. Let a NOS PM 8200 go a couple years back. I regretted it decided not to repeat that mistake. The 125 came with its original box and all paperwork, tooling and a dawg. There was a time in my life I could not even think of spending money on something like this, I am fortunate I have gotten myself to a place where I can. An America Muscle saw made by arguably the most known saw manufacturer in the world, in an era where America was at her height of industrial might in manufacturing. Nostalgic? Yes. Patriotic? Absolutely. Also fortunate, and grateful. This saw is another blessing to me in an already blessed life.
Ahh it's no longer mint now, may as well run it lots.I turned it over, does that count? lol
The PM605 (55cc's I believe) & PM650 (60cc same as the 610) used the same clutch cover as the PM610 with the little cut out,but only the 650 had the decomp valve.It was usually needed cause of higher compression due to different & more aggressive porting,tool steel rings vs cast iron ones on the 605 & 610.This 610 cleaned up nice. Looks better with the spike !

I figured it was due to something of the sort.

Just for the record, PM605 and variants are almost 58cc, PM610 and variants are just under 60cc...
Earlier models of the 600 Series used thick rings, later models were all thin ring including the 605 and other "3.4" variants.

The PM650, 655, and 690 (cut off saw) were equipped with a DSP (compression release valve) located above the muffler. These were dropped on later production and replacement cylinders for some reason. I think the location of the valve became a problem if carbon collected in the port, eventually scoring the piston. This was a problem on PM800 and DE80 models with the DSP located in a similar position.

SWEET, I LOVE IT Mark!!!Not as new, not as nice as Max's SP125 but I picked up and interesting piece of the McCulloch story last week. That's Randy Mac with his hand on the bomb hoist
My son Jeff spent quite a while today getting it cleaned up.
Now in the display.
