Mcculloch sp125/101b kart saw build thread

[Lee H]

This 125 came from the same fellow the last one came from. I bought it cuz the muffler guard.
Never seen one on a 125, Only the 10 series saws. It must be a winter kit to direct warm air into
the air box to prevent carb icing. I replaced the points and went through the carb and runs runs
perfect.

This saw came from another fellow member, It's a very nice saw and runs great. Unfortunately the fuel
tank must have taken a hit and leaks. So i'm on the lookout for a fuel tank that will hopefully match the
rest of the saw.

That’s a nice haul! How many 123cc Mac’s do you have total!?! And people say you can’t find them any more!

In 2004, I bought out a retired Mac dealer in Redmond, Oregon and ended up with some of those muffler guards. I always wondered what they were for.

 

[ManiacalMark]

I wonder if it was made so if you throw a chain off a long bar it doesn’t rip the muffler off?

HHMMM, Well i just went and counted. 12 797's, 14 125's, 5 101 kart saws, 5 797g's, then there are the SP105's
i have 3 and then the 120cc Mac's the MC75 and MC100 i have 3, so 42 total.

That may be what people say but to me the SP125 is the easiest muscle saw to find.
Look at the production run and the wood harvested during that time. Tells you that
Mcculloch sold thousands of SP125's. They are not rare but they are a very desirable saw.

That's always been my thought too. Mac made literally millions of the 10-10 style saws and variants, and even though they didn't make as many
125s, they made a lot of them. I think it was in '71 when they celebrated selling 3 million saws, and they sold a lot of saws after 1971.

They sold a lot of kart motors too. About the only 'rare' Macs are the BP-1, BP snowmobile motors, LeSabre, and the prototype kart motors.

Maybe the model 73/77.

Wow, so you were really needing the new haul!

I think it was a cold weather kit, now that Lee bring it up! Jj has posted that cover before, and we couldn’t figure it out!
I have thought about doing this for a long bar setup, kart chain guard and gear drive adjuster for chip clearance! The Mac cover sucks!

That is true! My area is hard core Stihl territory! My dad got old faller 045 for a fifth of jack and could have bought 090’s for $100 when Crown sold out, he kicks himself for not get any 090’s

 

[Lee H]

That would certainly give you chip clearance but i would use the bar adjuster of a
890 or 895, I think the one you posted is for the earlier Mac's like the 3-25, 4-30, 73, 77 etc

I agree Jacob, But the rarest Mac i have the model 49 which was only made for i think 2 months.

Yes! your correct, it was the closest example I found fast

If you would like a bar adjuster pm me your addy

Awesome saws Lee

 

[Al Smith]

Now those muffler guards .Both my two 125's plus the 105 have them . One of the big boys came from northern California and one from Oregon. The 105 if memory serves was from Minnesota or Wisconsin .

Gentleman, how to take the clutch off? I've loosen the nut, looks like a keyway slot on the spindle? But it aint coming off. Some heat?
