MCCULLOCH The official McCulloch thread

[joeymt33]

I like the 404 because it seem to stay sharper longer and I have 3 82cc 10 series saws using it. But only one with the eight tooth sprocket. They pull great. I can’t tell much difference versus the three eights.

I use one for milling and it has a 36 inch bar which means I get a maximum of 30 inch logs which I have cut before. Of coarse those are 7 tooth sprockets.

Here’s Mark H running my PM850 and long bar.

You guys don’t forget that 404 chain moves faster compared to a 3/8 chain even with the same tooth count on the drive sprockets. I’m sure the larger diameter sprocket even with the same tooth count is what can make the 404 chain seem to cut slower unless you have the torque to pull it

I would think the heavy .404 chain would be better off on 100 cc or larger saws .I'm not saying they won't handle it because it could .I also suspect the .404 would work better on the west coast soft woods than in our eastern hardwoods .I've heard but never seen they made longer bars for the large 10 series,SP 81 850 etc but the longest I've seen is 32" of which I have several .

I don't have one, but understand a 36 was made for the PNW loggers. I have changed a couple of Mac 10 series 32" bars from .404 to 3/8 and ran the regular 3/8 chain with no issues.

I have .404 chipper on this 36" bar, very good chain for all day cutting as it holds and edge a long time.



The SP125 is not the ideal noodling saw for these large rounds as the noodles really get packed in there. I had to shut it down after each cut to dig them out or they would start smoking.

As a side note a 36" on a 125 Mac is the perfect neutral center line balance .Some place I have a picture of same hanging by a rope from the front handle .Not nose heavy not tail heavy .

Yup, hey Stihl, take a lesson here.

The SP125 with a 36" is balanced better than a Dolmar 7900 with a 24" bar. Dolmar is somewhat nose heavy.

Yup, same 24 inch bar, nose heavy issue with a 044 or 460 Stihl. Great saws, however poor balance. An 880 is also quite nose heavy with a 36" bar, but an 090 will balance neutral with a 42" bar. Funny but a 2100 Husky will balance neutral with solid steel bars ranging from 20" through 32".

Regarding that I was given a 32" 10 series Mac bar which most likely was made by Windsor .It had a .404 tip but it was an .050 slot which I found odd .Evidently it might have been a west coaster because that size was never used on those saws in this area .I changed the tip to 3/8" .

.050” has been the gauge for this area for a long time: I am in the Minority running only 0.063”.

I think the gauge thing historically has been regional .The 48" hard nose that fits both my 125 Macs and 2100 Homelite is .058 x .404 .Fact I've got a few 10 series Mac small mount that are also .058 .
Then of all things comes a Stihl 024 that is .325 X .063 .That one threw me for a loop until I figured it out .

And an 090g will balance well with 50” lol

My 797 feels good with a 36” but I like a 42, the 32” feels too light , homelite 750 balanced nice with a new style 36” and my sp125 feels great with an an old 3-rivet Oregon, I need to try some full comp .404 the full skip 404 is rough

Here's a couple of old Mac's i rescued yesterday.
I believe the one is my first 125,alcohol,and piped saw.I still have to see if i can find out if it is actually an alcohol saw.No stamping s on the block
And my first cart engine that isn't in a saw,but it isn't stamped Mc20 like the one i have in a saw that is stamped Mc75

 

[Yukon Stihl]

Anyone know if these numbers tell a tale?They are on the bottom of the block wrapped in Mc20 cart stuffs.

I have a 797 Super MCculloch , I want to sell

What are you asking for it?

What plug are you guys running in your 101 kart saws, have an autolite 411, but it was either bad or the wrong heat range, plus I would like a shorter plug for clearance reasons... I put in s 3/8 reach plug and it(needs1/2) and it runs like a top, but I know it’s wrong...any help would be great! Thanks in advance!

 

[Bigmac]

Made some cuts with the kart saw...need some bigger wood! Lol

 

[Steve]

That is all going to be custom fabrication if you want to keep the sloper intake and carb. Otherwise jus put it in a doner saw using the saw intake and carb.

 

[Al Smith]

I've seen a number of 101 kart engines on saws in vid clips .From my perspective running the saw carb they really don't have any more grunt than a stock 125 .

For me it was $, can’t find 125 blocks anymore, I was given a basket case 125c got it running but the chrome bore peeled,it was way cheaper for me to build a 101, than find a 125, plus I already have a 125c and a 797. Last I heard it wasn’t cheap to get the cylinder replated, but any shop can bore a 101, and there are lots of pistons available
