McCulloch Mini and Small CC Chainsaw's

[asc20]

Ok cool, thanks for the info. What’s the difference between the 1 and 6? They look pretty similar without having both in front of me to compare.

I got it taken apart this morning and started digging into the carb, it seems to be an MDC 3, ordering a rebuild kit soon. Wasn’t too much of a pain to get disassembled/taken out of the housing, but we’ll see about getting it back in…

The starter on the MM1 is removeable, makes it much easier to get the engine in and out of the housing.

Presenting my mint condition Mac Cat. Never touched wood. The 38cc Mac Cat is the saw that started it all for me. Managed to get a beaten down one on ebay some years ago. Slowly builing it back together part by part had planted the little seed within me when it comes to loving old McCullochs. Couldn't pass on finding this one new with original packaging.

It's hard to imagine how someone buys a brand new chainsaw, and after so many years it never gets used!

That's a very cool find, thanks for sharing.

One of the saws that I acquired fairly early in my collecting was a late model PM6, complete with a brake. Not knowing what direction my collecting was going to take, I sold it...





Jeffrey - Congratulations on the NIB Mac Cat complete with GLX chain, very nice. The 300 Series saws have really good engines, but the ergonomics on the short handle version make them less enjoyable to use. The 330/340 models are actually very comfortable to operate, but my vanity would not let me use one in a public setting.



Since that photo was taken I have been 3D printing the airbox covers and now have OEM or 3D printed covers on all the saws in the display.

It's interesting to me how (according to the Mike Acres site) the PM6 and Mini Mac were available at the same time up until about 1974, I wonder if the PM6 was marketed as more of an arborist saw while the Mini Mac was more of the homeowner model?

There's a PM6 for sale locally pretty cheap, but I already have several small Macs and now I have the itch for the bigger Mac saws haha.

Any tips on getting the fuel filter in a MM6? Plus, should the large end go in the tank first?
It really is putting a square peg in a round hole.

Continue to push.

ok, a little wd40 a couple twist and got it in. Was afraid I was going to crack that old plastic.
Next item noticed missing is the oil pump check valve part no 86438. Looks like a piece of rubber hose that's about 7 bucks on ebay shipped. I dont understand how it works other than looks like it blocks oil coming out of tank maybe.
Is there a known hose size material that is a work around as I have two more to probably replace coming up.?

If you saw has an automatic oil pump in addition to the manual you do not use the check valve.

If you need a check valve, send me you contact information and I'll put one in the mail to you.

FWIW, I cannot say I understand how it works without having the saw and parts in front of me, but I do know they will not operate as intended without it.

I can vouch that the manual only oiler does not work without the check valve. I learned that the hard way.

 

[Gumneck]

Ok, great....one less thing, that's good.

I guess this technically is a MiniMac 6A for parts lookup but didn't see a parts breakdown for an automatic not showing the pump check valve.
