McCulloch Chain Saws

[minosi]

I also picked up this 440. It has a new cylinder and MONSTER compression. Idle is smooth, that's as far as I've gotten...

Notice the super rugged rear handle brace that someone fabricated, almost nicer than stock. I'll replace the front frame bracket and maybe the muffler.

This one pulls like a 797 with the DSP valve plugged. Seems like there may be bar oil, or storage oil, that has greatly increased compression. Pretty sure the motor is fine, just needs some investigation.


Here's the lot:

Don't mind the IEL, I always try to buy a saw to sell, keeps the CFO (wife) happy when the CAD habit is self supporting:msp_biggrin:

The PM850 is running great. The compression this saw has is unbelievable.

I hope the video links up OK.:msp_confused:

If the Southern ME GTG ever happens, I'll show you the way my friend!

Andy - Nice haul! But the REAL jewel in all that is the 'Pioneer' scripted emblem on the top. They are VERY hard to find.

ODW - Nice saw! Can't wait to get mine done.

.... sure didn't last long. SOLD!

There were many of the 1-41 and 1-42 saws sold without the lower brace. You can add one if you like since there were perhaps 1,000 other models that used the same parts.

The saw only has a manual oiler, to access the piston if needed you will have to remove the oil tank and fuel tank from the front of the saw. Best was to start is clean the oil tank out as best you can, add some light weight oil (SAE10W or similar), and start pumping. If you are fortunate, it will start working.

If not, the next step would be to remove the external check valve, see Carl's 250 photos a few posts back for a good photo of the external check valve. Remove that cover, carefully remove the spring and check ball, spray a little WD40 down the passage, and hope for the best.

Saw arrived on Monday.Very strong compression,it was missing that oiler 'button',which I had in that assortment of parts bought 2 weeks back.Oiler works great.Adjusted the carb,its running great now.No other parts need replacing.I had a new stainless steel bucking spike that was a spare lying around for the 125 (same bolt spacing but its the smaller one) so I added that too.

2-3 pulls cold,1 pull warm.Air filter is pretty good,was very clean.Original 18" rollernose bar that has expected wear,.404 pitch chain is about done though,2-3 more filings & I'll toss it in recycling bin.

Picked up a reprint parts list for $6 a couple weeks back also....That's a must have for working on these old beasts.

Pm700

ODW- nice job on that oak.
i hope to hear my new- to- me PM700 soon. i think i'm gonna like the sound, thanks for the preview.
went to the local husky shop for some gaskets and spied this behind the counter. i guess it was a trade in,don't see many old macs down here. i asked how much and it ended up in my trunk !
everything is there ,pretty much untouched, but well used, just the way i like to find a saw.
the only thing missing was a clutch spring and it's retainer. there was an exit hole for the retainer in the cover but no sign of the spring. i imagine it left in a hurry too. i guess there's no cover plate on these clutches., eh ?
where can i get a couple of springs and another retainer for this clutch ? i remember hearing of of some marine store in detroit ? that had mac parts. not much on the bay.
it also needs a gas cap as the homelite one on there doesn't quite hook up enough to seal the deal.
thanks for any help.

.. or post in the 'Beg for Manuals' thread and get one for nothing.

My printer's messed up now,its about done I think,almost 7 yrs old..Easier to buy a few cheap reprint or original manuals than buy the ink,print them myself and/or replace printer at the moment.

Got around to investigating the recent Muni-Auction PM700 acquisition that had the fuel leak.

First, the fuel line was cracked at the carb intake, but I'm not sure that's where all the fuel was coming from unless some kind of siphon effect occurred as I added mix to the tank.

Second, the fit of the fuel line through the tank was pretty loose, though I hadn't added enough fuel yet for it to have been leaking there.

Separated the tank and it looked like someone applied "something" around the rear of the tank seam in a couple of small spots which could have actually caused a bigger leak problem at the seam if the original leak was indeed the fuel line in the first place.

The tank gasket and tank mating surface areas look pretty good with no visible deterioration at all to the gasket...., just the indent from the ridge on the tank cover. It was easily removed and still looks pretty fresh.

So can I swell the gasket a little somehow for a better seal prior to re-using it, or should I just go with the Indian Head sealer?

And without searching all day for this answer, is there a Tygon fuel line alternative that is nice and snug through the tank as an acceptable alternative to OEM, or am I hittin' the bay for a new line?

Finally, is Red-Kote available anywhere in smaller quantities than a quart container?

I have purchased the Stens replacement fuel line and done the "teflon tape trick" both with success...one obviously cheaper than the other...it only take 3-6 wraps around the buldge to resolve. The Stens line will require a filter with a nipple fitting vs. the stock line with the felt recess. I usually buy the "80cc+" filter size just to let the old girls drink.

You can try soaking the gasket in tranny fluid overnight to swell it. This usually works if the saw sat for decades with a dry tank.

[Warped5]

Pogo - Don't lose the anti-kink spring from inside that fuel line (if there is one) .... PM me if you need a spring. I may be able to locate a decent fuel line around here, too.

The smallest container of Red-Kote I could find was a quart.

Nikolas PM'd me for compression numbers on the 440's...obviously happy to oblige as I needed to investigate one anyways.

Here is the first:

Pretty average numbers for these old saws, seems like they are always 120-140.


Now the next, "pulls like a 797" one:

View attachment 310876

View attachment 310877

Ahhh yes, that does say 200. This saw has no bar oil in it (tank stored dry) it pulls nice and smooth with no plug.


SO am I "lucky" (used loosely as the thing is a bi*ch to pull) or am I missing something?


-Andy

 

[Warped5]

Andy, with the saws you've been toting home lately, you're not 'lucky.'

You're 'special.' :hmm3grin2orange:

 

[rwoods]

Maybe that last saw has the smaller kart motor in it - check for a removable head or for something in the chamber taking up space. Ron

I agree with Ron. That saw could easily have a
kart motor in it.
I bought a Mac way back when before i knew about
kart motors in saws and was trying to get this
particular saw running and had the time of my life
trying to start it. I literally had to stand on this thing
to pull it over and get it running. Only to find out it
has a MC75 kart motor in it. It's still a bear to start
but fun to run.

What doe's yours have for numbers on the bottom of the block?
