McCulloch Chain Saws

Airbox first. I believe the oil/fuel tank assembly overlaps it.

That's exactly what I was thinking. Thanks for confirming, the service manual doesn't have much detail on the order of assembly.

You would figure it out real fast doing it ass backwards.

That's usually how I learn anything....screwing it up the first time!

Only the first time? You must be a fast learner!!

G'day friends! First time posting here.

I've got a question when it comes to my McCulloch CP70 that i managed to get my hands on. I am in need of a new muffler since the original one thats on it has rusted away beyond repair. The illustrated parts list says that that it is the P.N 65532. Now considering that i am living in Europe said part is difficult to come by. Are there any alternatives that i can put on there?

Airbox and reed assembly together and installed on the cylinder. Hopefully it's all together correctly....

You'll get the saw together beautifully I'm sure. If you're going to try using the original flatback, it will have you questioning whether or not you forgot how to do basic stuff, like counting to 10. Some work well, some don't. I redid one for my S550, choke style. At the time, it would start right up and idle. I pulled out a couple months later, one pull and fuel is pouring from the muffler.

Welcome! There's a couple of fellas here who may have a replacement for you...

Thats an excellent way to sum them up!

Jeffrey Link - the muffler from any of the 60 or 70 cc models (PM60, SP60, 4-10, 5-10, 6-10, 7-10, PM700, SP70, etc.) will work although the PN may be different, or the design may vary. It will be necessary on some of the versions to add the hole for the DSP to vent into the muffler body.

There will be others that will also work but those are a good place to start.

You will not be able to use any style muffler from the 54 and 57 cc saws as they do not fit the larger displacement cylinders.

I think I'm going to try and rebuild the flatback and see what happens. I'm fascinated by the airvane idle whatever gizmo and the primer. The primer even appears to work already. I've never worked on a flatback carb, but this this one looks super clean and shiny.

If I hate it...I have a Tillotson from a Mac 250 parts saw I could throw in there.

I missed out on a free 10-10 today... not quick enough!

That stinks!! I hate missing those amazing deals.
There was a guy selling a clean 10-10 for $25 a while back in my area. It was gone before I could even contact him.

Points adjusted to .018" at top dead center:

I still need to test the coil but I am hopeful to have spark, these old Mac points ignitions are pretty darn reliable.

It wasn't that I needed another 10-10 - I don't.
But it needed me.

That's how I ended up with 4 Mini Macs... they're like unwanted strays.

I'm keeping my MAC110, because it was my first.

My Mini Mac 30 was my first and only saw for the better part of 15 years. I have never even had the carb apart. If I went to the shop and gassed it up it would fire right up.
