Number stamped on the bottom of the crankcase?
That's the model used in Australia and New Zealand. Welcome to the site Dave, just messin with the new guy.
PG600, my local small engine shop has a nice old Mac he was going to put on a shelf, but said he would like to sell it. It looks like my Mac15, but no stickers or tags, would it be stamped on the bottom? Sorry for the hijack.

Possibly 640 or 890 by the paint scheme. It has an auto oiler which was only on four models I believe. No decomp rules it out as an 895 Underneath it should show numbers on the crankcase. That has an early recessed starter cover which makes me think 640.
Looks like the 640 I just packaged up to ship except I don't have that muffler guard/cover and my af cover is yellow not black.
Only the Mac15 looks like a Mac15, they are the one and only model made that way, I have several but have never looked at the bottom of the crankcase to see if they are stamped, just so easy to identify them by looks alone.
I-60?

On the bottom of the crankcase is stamped 740, 840, and 460. The 740 is a direct drive. I am guessing it is an 840

Nope, the tank covers look way different and a 1-60 doesnt have an auto oiler.

Then there you go, 840 for the win.

Thank you for the help
Thanks, a 15 it is then.
Was at my father in laws scrounging some wood & he offered me a couple of McCulloch's, 1 of which is a worm gear, or worm drive. The other is newer, more plastic & yellow if anyone is interested in seeing them I have to go back tomorrow & get the rest of the wood. I could take some pics if any interest

Pics are always good.
The 640 does not have the Super Series engine and is only 80 cc displacement (2.125 bore x 1.375 stroke). Bore and stroke are smaller than the 840.
The 740/840 has the Super Series engine and no compression release (DSP). 99 cc displacement (2.165 bore x 1.635 stroke). 840 is gear drive.
The 840 has the automatic oiler, driven off the output shaft so it only works when the chain is moving.
The third number might be 450? Bore is the same but the stroke is shorter (1.5").
