I bleed YELLOW!
I hunk I sent one to Ted with the that seal and it leaked on him.
Maybe he'll chime in soon.

I picked up this one(D30 I think?) for $35, pulled the muffler and it looks good inside. It also fired on prime, so now its going to sit and wait until I have time to rebuild it.
Just finished this off yesterday after waiting a month or two to find a carburetor to replace the flat back. Runs great! Now all I need is some wood to test it in. It has NOS piston and rings.

What Did You Do With the flatback? They are great carbs I rebuild all of mine. I'll never understand why most take them off. If that had the original flatback on it and you don't want it anymore I could use it.

Anyone know a replacement bar and chain on a mini mac 110? I'm going to rebuild the carb soon p&c look good and it's a complete saw. Just hoping to get a sprocket bar instead of the one that came with it. Would be willing to go 12" b&c if needed instead of the 10" that came with it.

The big one looks like a 1-76, they are brutes.
tpence - you will need to be more specific, some Mini Mac's came with 1/4" pitch chain and some with 3/8 LP. If you change pitch you will need to change the sprocket/drum as well. There are lots of bars and drums offered on e-Bay all the time. I do have a good supply of 1/4" pitch chain if you decide to go that route and can't find the chain reasonably priced locally. I have at least one with a 14" bar, way too much for that little saw but a 10" or a 12" work well.
I can probably set you up with the full complement, sprocket nose bar, drum/sprocket, and a piece of new chain if you strike out elsewhere.

Mine is the later 2.0 cubic inch 110 with the Zama carb. 10 inch blade. Best I can tell is its 3/8 low profile but I'll try and look at the bar and be sure
Edit and thank you! I may definitely hit you up on that offer I'll see what I can find locally first though. Not a lot of info on these mini macs except that nobody wants to work on them. It's not the best limbing saw but for $30 it makes up for a little work not having to buy a $300 echo or even higher stihl. Especially since I'm just a home owner and the bulk of my cuts will be with my echo cs590 and my husqvarna 51

Looky there just saw an Oregon bar and chain pop up a 12 inch on eBay with sprocket nose. Once I find out my chain pitch may jump on it

You can always replace the drum/sprocket to match, 3/8" LP chain is much easier to find these days.

May have to ask you some more questions once I get it running on chain, bar, and sprocket combinations the hardest thing I've seen so far isn't finding the right style chains. It's the amount of drive links. I think the 10 inch is 38 drive links and the ones I have found are over 40 links for a 10 inch chain

I live in Canada and can't quite stomach the exchange rate and shipping costs for a flat back carb kit. Plus the primer was leaking like a sieve. I also have another odd-ball mac carburetor that came off a super 44A that I replaced with a tillotson HL series but it's not like the flatback off of this saw. The tillotson carbs are just easier to deal with and I have lots of spare parts for them.
The model in the lower picture is a 795, thanks to Mark for sending me the IPL.
Is there such a thing as a list of the gear drive saws? I have one with what looks like 1-76 and 772 stamped on the bottom, the 76 I am not sure about as the stamp is not well done. The saw looks like a 1-86. The saw could use a better muffler, it looks like the 795 muffler may work??

1-76 is direct drive and 1-86 gear drive. Both 99cc saws. 772 probably the serial number on the right side of the block I'm guessing? As far as a list McCulloch put out a publication of saws and production dates that lists direct drive or gear drive.

A D30 wouldn't have a primer on it but should be the early flatback choke carb with a spring and push in and hold choke button. That's why I was interested in it as I thought you had the early flatback carb. Shipping can get expensive yes but I'll pay it if I want something. I like flatbacks they are fine carbs regardless of what others say. A lot of guys can't work on them and get frustrated. A little finicky but still good carbs. My Super 44A has a factory tillotson on it, HL19 I believe.

Have a look at this file from McCulloch.
Gear drive saws are marked with a double asterisk **
The 33/35/39 Series and the BP-1 are also gear drive saws, crankshaft rotation is 90 degrees to the chain movement with a bevel gear set up in the front.

Yes the D30 does have that carb in it. I pulled it apart last night and its badly corroded, so its soaking in carb cleaner for the time being, the pump diaphragm is fine, but the metering diaphragm is too stiff to work. The 795 had the later model flat back in it with the primer. My super 44A also had the early flat back, or something like it. I have nothing against the Mac carburetors, I would gladly use them if parts were more readily available, the governing spring mechanism on the late model flat back is pretty slick.
I see Mark has posted pictures of the carb and a mountain of the pump diaphragms. What do you guys use to soften up diaphragms when you can't get replacements?

Also Mark's post on the various mcculloch carburetors is probably one of the finest technical help things I have stumbled across on here.
