McCulloch Chain Saws

[Eccentric]

Very interesting. The Oz 73A looks like it has a 77 tank. Heck..........it looks a lot like a 77 in general. I'm curious to see what's shared with what model...opcorn:

Heres the 47a Australian model i own

and a brocure of the 73a

Mac 73 American

And a Mac 49 i own

And a Mac 73

The main difference between the American and the Australian models was the air filtration system

Great stuff Cliff and Bob. That 49 seems to be a RARE bird. At least in the US..........the 49 is basically a 77 with less displacement (If I understand correctly). They look identical on the outside (77 and 49).

The American Mac 49 is indeed a rare bird i have had mine for a few years now which i bought off ebay.com and imported out here

Yup, work and family have kept me out if the shop lately. This morning I filled out my order to finish two yellow threads that never got all the way done. Tomorrow, I have a stop to finish a green one.

If someone ever pisses you off squirt that tube of valve grinding compound in somebody's engine(or a fresh quart of oil strategically placed) ....wont take long for a rod to come out the side of the block......just saying

Pieced this 3214 together with parts from 08F150, 67L36driver and a few other members. Did the usual muffler mod and replaced all the usual maintenance parts including fuel and oil lines. Have a new 14" mac bar and chain on the way, once I get it bolted on ill fire it up. I took apart and cleaned up the carb but i didnt replace the diaphram etc....yet. I figured worse case scenario if its acting up the carb is easily accessable unlike the mini's. I know these saws are plastic and MAC's last run but they are pretty reliable. Have another 3516AV to fix after this one, we will see what happens

Its a bust, carb needs to be gone through. Only runs for a second on a prime and then dies. Carb doesn't appear to be sucking fuel. Zama RB-39 rebuild kit is on its way.

HA! Yeah, I know a jerkwagon or two who probably deserve it, but malicious property destruction has never been my style. I like to be more subtle and suggestive and allow karma to cut, sort, and stack the rest.

Thanks for the photos and information Bob, very interesting to see the differences between the US and Australian versions of the saws. Sadly, my 73A has a few broken bit like the rear handle. I can probably clean it up and make it look O.K. setting on the shelf but I don't think I can make a running GTG saw out of it.

I will follow up with some additional photos once I get all of the snow moved and the first family Christmas gathering wrapped up.

Minis

Since the are a few of you guys now that love these things.....
I need some mini mac info.

My neighbor, whom I owe big time, gave me a saw to fix up for him. It was his Paps and it means a lot to him, so I wanna help him out. I have a pile of these and would like to use a running newer engine in his mini Mac 1. Can I do this? Will the newer engine fit? Fingers are crossed for good news.

Yep, it will bolt right in. Just check out the kill switch situation if the engine you want to use is from a later model with electronic ignition, off the top of my head I don't remember how the newer ones are wired but the old points boxes have a stab the switch slides into. You will see when you pull them apart. Shouldn't be a big deal either way.

Another thing is your going to be fighting that pain in the ass fixed recoil on the MM1, just make sure the starting pawls are the same if not swap em on the flywheel. Good luck.

380 spark plug cover

The spark plug cover on my 380 is really hard. Do you guys have any suggestions for softening it up? I was thinking of soaking it in tranny fluid but if you have any better ideas, it would be appreciated.

Thanks

Has anyone ever seen a 10-10 air filter cover like this? Just wondering, The saw is on Ebay and looked odd...

Joey answered that either here or in the eBay/CL thread ... it works together with another piece (not pictured) that fits over the engine/muffler area to provide the carb box with heated air. Sort of a cold climate kit.

Thank you very much. That's what I was hoping to hear.
