MCCULLOCH The official McCulloch thread

[Bigmac]

I decided to pull out a set of calipers to better describe my issue. In order, new bearing, old bearing, new bearing, old pin. The only difference I see is my new bearings are B-88 S bearings and the old ones (as well as all the n.o.s. Mac bearings I've seen) are B-88 C, but I don't see any way of ordering "C" sized bearings.

Quantum Racing has an oversize 1/2" wrist pin available:

Taking a break from the CP's fun, I finally chipped the SP. I still need to get the tune set and it might need a fuel filter too, but at least it runs again.

Some pretty healthy chips coming out of it!

Off the roll 1980-something Oregon .404 square ground chain with a couple horses behind it makes some good chips!

Grip it and rip it . Lol

If I remember correctly 1/2" Oregon chipper is around .040---.045 . It will pull big old chips and about drag you over the log .Fact I've got a NOS Oregon 7 tooth rim for 1/2" but I'm half afraid to even try it out on a 125 Mac .

 

[Vinnywv]

Lol guys. Those big saws are fun. I actually have a 1/2" x6 rim sprocket also. Talk about grunt. Ive tried.it on a 125 and its fun. I have a 7 too. Either one will make ya hold on.

 

[heimannm]

I am around 0.060 on the SP125 with a 16" bar....

Whew!
Talking about taking almost a 1/16" "bite" with every tooth!
Would be "fairly" aggressive.
With a 16" bar I could definitely see it.
125 ccs probably wouldnt care much, as long as you can hold on.
Make sure shes on the dogs before you pull the trigger.

Actually I've never filed a .404 chain to the point it needed the rakers filed .Some of the real old chipper chains might have been but I never checked .That said I've worn out buckets full of 3/8" chain .I run those until there is nothing left to file . During that time I might only hit the rakers a couple of times . What I do do is open the gullet clear down to the tie strap every so often so it carries a larger chip before it rocks out .

 

[Al Smith]

My biggest problem is cutting dirty wood or on the ground because unless you are exceptional good you will kiss the dirt .I'm good but not that good so I get plenty of file duty .

 

[Al Smith]

Ignitions can be a pain in the behind on shelf queens .If they are set up rich after a period of time the carbon fouling will make the spark plug ineffective .I've had this problem on just about everything I own .
Recently trying to get a super 44A Mac running because of the way the plug is oriented I could not get a plug wrench on it until I ordered a long socket scrench . I also ordered a plug sand blaster because I misplaced the one I have .I've got about half a drawer full of plugs of nearly every size ever made . I might never need to ever buy a spark plug again if they clean up .
A little off topic but on old "Ollie " my Oliver dozer that sits more than it runs the plugs were fouled and I only had 4 new ones .Found two old ones I thought would work but when it warmed up I had two cylinders out of 6 misfiring . Not a good thing trying to pull down a 100 foot tree .It had enough on 4 but it was nip and tuck .

 

[heimannm]

No spike on that one, if it pulls into the cant and the spikes stick it really slows the cooking making process...

I stumbled on this pic looking for another .Front to back Sp 105 with a 24" Sp 125 c with a 36 " ,Sp 125 with a 48" .The 125C is the one I installed an iron liner in and since have not ran it long enough to seat the piston rings

I'm going to that Ohio "saw fest " thing .I'm going to leave the dawgs on the saws .If they hook ,they hook . The last time I took them off it took me a month of Sundays to find them all plus the bolts . I'll take a couple of McCullochs but only operate one in competition and that's an 805 with an early 850 engine in the 5 cu inch class .The others ,a Titan 70, SP 1000 (partner P100 ) plus the SP 125 is only to show them because these models are rare in Ohio .I might run the 1000 if I can't get the Husqvarna 2100 CD started because it can be a bear at times . Reminds me of my first wife .
