MCCULLOCH The official McCulloch thread

[simsponsawshop]

Hmmm guess I will try a coil out of one of my good runners and see. I've got plenty of parts to swap so should be able to narrow it down.

Small Mac's this week.

This one needed fuel line(s) and the stop switch replaced. I gave it a good cleaning inside and out as well. Where do you buy that LP Skip type chain?



I replaced the primer while I was working on it, these are B/4 photos...



This one came to me a while back, thought I'd clean it up and get it ready...I want to have a few "ready for sale" saws in the shop for the uninitiated so small saws with a chain brake are in order.

Above was really yesterday's post, I just forgot to post it...

A couple more today, the Mac Cat is the anti-vibe version of the 32/35/38 cc saws. Compression was pretty low so I put a NOS short block in it, basically a new saw now FWIW. I did install a chain when I took it over to the museum building.





I will get some better photos of this one, a really late model McCulloch (2005) with excellent compression (200 PSI+). Starts, runs, oils as it should. I am tempted to take this one out and cut some wood with it but parts are pretty hard to come by so I may just put it on display as well.

Mark, who owned Mac when that last one was made? Just curious. I know Black and Decker owned them for a bit. I know some of the "Titan" series were Italian made(or so ive been led to believe).
Just wondering about the history.

 

[Gizzard]

At present McCulloch is a Husqvarna brand. Current website has 3 gas powered saws and 1 lithium battery powered saw for McCulloch.

 

[Dream]

I saw the Husqvarna part little while ago. I know they were tossed around a good bit. Just wondering who had them when that last one Mark posted was made.

I think I have it sorted. I went through and rechecked the points, the coil air gap, and the wiring and kill switch, still no joy. Swapped the coil from the 2-10, and all good.
I made another wire for the old coil using a homelite coil wire I had here and put it on the 2-10 short block. It still seems weak and intermittent so I may be looking for a coil. I guess I should have just left the 2-10 as a parts saw. Oh well.

Here is the best information I have been able to piece together regarding the McCulloch timeline:

1931 - R.P. McCulloch starts McCulloch Engineering in Milwaukee, WI building centrifugal superchargers. That business was later sold to Borg-Warner.

1943 – Changed the name to McCulloch Motors Corporation, primary products are drone engines for Radio Plane and chainsaw engines for Reed-Prentice.

1946 - Move to California, purchased land near what would become LAX (airport)

1964 - Opened plant operations in Lake Havasu, AZ

1974 - Sold to Black & Decker

1977 - R.P. McCulloch dies

1984 - Private/Employee owned

1988 - Moved to Tucson, AZ

1999 - Bankruptcy, Europe goes to Husqvarna, North America to Jenn Feng (Taiwan)

2003 - Jenn Feng & MTD sign a distribution agreement

March 2008 - Husqvarna acquires Jenn Feng, McCulloch is now a brand within Husqvarna

Robert Paxton McCulloch was married to Barbara Ann Briggs (Briggs & Stratton, yes that Briggs). I thought I had read that his uncle was Ralph Evinrude but I cannot find any confirmation of that. He was in direct competition with Evinrude and others when he bought Scott-Atwater and went into the production of outboard engines for boats...coincided with their move to Lake Havasu, AZ where they had an ideal testing site. There was an episode of the old television program "Route 66" based loosely on McCulloch's activities in the outboard engine game.

Practicing social distancing yesterday... Made up a new loop of chain for the 1-70 and took care of some maple butt logs. Its been a couple of years, but ran flawlessly. Not bad for 60 years old!

Thanks Mark.
They were employee owned for a good while there.
Thought there was an Asian company somewhere in there, just never knew who.

Where do you buy that LP Skip type chain?


Mark

I've seen a few of those 91 LP skip chains on small battery powered chainsaws but have never seen any of those chains for sale. I thought I had one but can'r seem to locate it.

I wonder if they come out of China and are just sold to manufacturers making those little saws.

Looking at the one my younger brother had, I doubt the saw would outlast the chain.

I have lots of little gas saws I could have given him but given his outstanding ability to turn any project that involved power tools or ladders into scary accidents, I didn't offer.

 

[heimannm]

That is a handsome old saw John.

Here are some photos of the MS2050AV. I may have to take it down to the local brush dump site and cut up some ash logs since the city has been taking down additional trees recently.

I found another plastic Mac in the attic as well, this one is only 42 cc and has less than 90 PSI compression so I will just move it over the to museum as is.







The 2050 and the 42cc Eager Beaver are both Jenn Feng era saws. The 3200/3500/3800 saws shown above are actual McCulloch from the end of the Arizona period.

That one cleaned up great Mark.
So I assume a Pro 1010 Auto was still a 54 cc?
What we're the differences between it and a 1010A?
Sorry for all the questions. Know you have a lot going on. Just trying to pick up a little knowledge along the way.

 

[heimannm]

Did you ever find one of these in the bottom of your oil tank and wonder where it came from?



And the answer is





Normally there was a small piece of felt in the space with the vent hole, evidently to minimize the amount of oil that would leak out if/when the saw was tipped on its side.

Dream - 54 cc like the other 10-10 models. The biggest difference between the Pro 10-10 Automatic and the 10-10 Automatic is the Pro 10-10 Automatic has the Pro Mac style and fuel tank and so the PM type air filter. The 10-10A and 10-10 Automatic saws all had the domed type filters that are hard to come by these days.

I remember trading you that rhs 10-10 Mark for a 3-10E. That was a long time ago!

 

[heimannm]

I have lost track of the history of many of the saws I currently own...I may have to start compiling a notebook with model, serial numbers, and where they came from.
