So - rummaging around for some odds and ends I needed for a project I finally got tired tripping over a little yellow chainsaw that's been sitting in the dirt and junk on the floor in the back of the barn discarded by the previous owner for at least 15-20 years. I meant to toss it myself by never got around to it. So I look at it again.

The bar and chain are complete rust. The body is covered by 1/8" of grease and dirt, only a little yellow showing through. I wipe if down with a rag - it's a McCulloch Power Mac 6. (Later checking shows it's from the 1969-1974 era.)

I wonder what would happen if I put a little fuel mix in? I douse the chain with oil and work it around a little - add about 1/3 tank of 50:1 I had nearby - and on about the third pull it starts to sputter. A few pulls later it's running. And loud - whoops - no muffler at all. But it runs well, idles well. Never touched the plug or anything else.

It clearly needs a chain and a bar, but otherwise seems to be in good shape. Not a bad little trim saw. (Word was when it was introduced it was the worlds lightest chain saw).

Like I said, I know it hasn't seen the light of day for at least 15 years. Can't help but like a tool that wants to wake up and go back to work. Bars and chains are easy, I've tracked down air filters, but anyone have any idea where a muffler can be had? And what's the right mix for this era of McCulloch? (I assuming the 50:1 I had for my Stihl is too lean - probably 40:1 or 32:1?)

32-1 should be fine.

One thing just to note, Stihl's only run 50-1 if you use Stihl 2 stroke oil, otherwise they run on 32-1. Putting cheap 2 stroke oil on 50-1 through your Stihl is going to kill it.

Didn't realize that, although I've only ever used Stihl oil.

From some more info I've come across I've gotten the impression that getting these little McCullocs to run well is voodoo and aren't worth wasting too much time on if they don't cooperate easily. Amazed me this little bugger fired at all but it actually seems to run well. Also after thinking more about it I'm going to revise my dead storage estimate - it has to be at least 20 years since this thing saw the light of day.

There's a parts saw on evil-Bay, but it's missing the muffler as well!

How long will it take to see this happen??
I have two stihl chainsaws 025 and MS260/026 and a HT75 pole saw, the 025 is five years old, pole saw 4.5yrs and MS260 3yrs...all have been run 50:1 with Echo oil.
The 025 has the most hrs on it and I can't even begin to guess.
I used it this morning and it ran as good as the day it broke in.

It must be another brand of oil than Echo that it is not good on a Stihl.

Tim, I dumped a working McCulloch a while ago, not worth the effort. It ran erratically, it was loud and it was a pain to start. I picked up a Stihl 013 (really small and light) for free and overhauled the engine for £30 (incidentally, scored up piston, possibly from insufficient oil), much better.

Wushaw, I would assume that Echo oil is as good quality as Stihl oil, so not a problem. If you went out and used the cheapest oil then it might be a problem at 50:1.
