It is but wrapped around a 10-10S engineIs that the lightweight? Love mine!
You're missing a screw there J2t
Yeah it's stripped out. Meaning to re tap for M6 for a good few years now

I only remember using one chip, I believe it was a NOVA II but I cannot confirm that. That was on a 10-10 McCulloch and it certainly would exceed 6,000 RPM...
I agree with Mark. That could be an issue. I have had an obstruction cause that before.It could be that your throttle rod is out of shape and not letting the throttle close all the way to the stop. Next time the saw is running try forcing the throttle closed at idle and see if it slows down.

I have heard that said of many MAC enthusiasts.You're missing a screw there J2t
Thanks Rallyeguy - I will give that a try once I get the kill switch problem fixed!Ive found that on 2 jet carbs on the mccullochs the low jet can have some crossover effect on the high jet. With a fixed high jet, this may also be what you're running into. The saw should four stroke when free revved, but clear up under load in the cut (assuming you're running a sharp chain). If its not clearing up in the cut, you could try to lean out the low a little and then adjust the idle screw accordingly if idle rpm changes. This might get you where you need to be...
It's kinda like a four barrel primary's first then secondary's but primary's still function.Thanks Rallyeguy - I will give that a try once I get the kill switch problem fixed!
Awesome Max,So I did a thing... Yes it is NOS...View attachment 1183667View attachment 1183670View attachment 1183673View attachment 1183674View attachment 1183675
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.Holy crap you must have robbed a cartel for that
That Mark guy...He funny!Max is the cartel...
Would of done the same , only go around once in life, go big or go home,I saw it, thought let it go, then I thought when or where will I ever get a chance at a NOS 125c again?

That's what I was afraid of - everyone just seems to replace them with SDC's, rather than monkeying with them. I have an SDC 37A that I can slap on (even though my desire was to keep it as original as possible). Did the same thing with a PM 55 that had a single jet Walbro.I think the Tillotson they often used on the 70cc saws was a governed carburetor, they always run very rich at high speed as that was the governor does, dumps more fuel as the RPM/vibration increases.
