Well deserved rest then
A couple of my 10-10's have had that green primer (I guess it's primer). Be a very nice saw when you get done with it.

I think you're going to have to look at the rings. Both sets are listed in the IPL. I'm not sure of the ring dimensions though.
From IPL 11-600052 7-10A 10/71 to 12/75 IPL 91123
87166 1 Ring Set - Piston (Wide)
89732 1 Ring Set - Piston (Thin)
From IPL 10-600052 MAC 7-10A CHAIN SAW 09/70 to 09/71 IPL 85017
63290 1 Ring Set - Piston
There are three more IPL's I can't find for the 7-10A's
Ah right they (mac) seemed to change there manufacturing processes all the time. Thanks Brian it's a great saw now runs really well but really want to experience a fresher one.
Can you tell from the picture? Or are they not as noticeable do I need to measure them 1st?

The extra hole in the muffler is where the lever operated DSP on the older saws vents to.
I had a couple "mini adventures" with my Macs over the last couple days.I got out the Eager Beaver 2.1 to cut up somer downed limbs yesterday & found that the oiler wasn't working.I replaced the oil pump & oil line back a couple of months ago & I found out after I'd put the saw back together that I should've coiled the excess oil line when I put the tank back on.The result was a pinched oil line.I fixed that today & it's puking out oil good now.
I had a couple of 10-10's that gave me some minor problems too.Tim helped me get the one 10-10 going back in Dec.& I always thought it was quite loud.I got it fired up to cut up a pear tree that was pretty much destroyed by the wind this winter.That saw made my ears bleed (not really),but my ears rang for quite a while later.I pulled the muffler cover off last night & found that the baffle was missing.I found one on Feebay for $17 + shipping,sorry not paying the extorshonists there that kind of money.I found another baffle on another site for $6 + shipping,much easier to handle.
The other 10-10 that I'd bought about 6 weeks ago just needed a new fuel line & a carb rebuild,plus it needed bar plates.I put the bar plates on Fri.along with a 20 in.bar & chain.I fired up the saw,but the chain wouldn't turn.I think it's got an old .354 clutch drum on it,but that shouldn't make it bind that badly,right?I found a new Oregon rim & sprocket on Feebay last night for under $21 & free shipping.I'm going to look tomorrow,I might have a spare .375 clutch drum laying around out in the garage.The one I just bought will come into play on the 2-10 I'm working on.

Had a little yellow saw fun today! I think the 1-52 needs crank seals though. The hotter it got the more the idle creeped up.
Thank you for that thats very interesting Have you got any pictures of your 7-10 piston? And nice pic is that a 10-10?
If you are going for a full set of 10 Series, make sure your shelves have a lot of room. Considering there are at least 14 different model numbers for the 10-10 saws alone, there are quite a few saws to collect.
Today's project involved the Titan 40 setting on the bench on the far right in the photo above. Back story is, this saw was part of a larger haul I made last June on my trip to Oregon. There were a number of saws that had been used in the Blount/Oregon factory for some kind of testing, presumably of the kick back tendencies of different chain. Notice below how the rubber on the front handle has been removed so it could be clamped in their test rig. I also presume the broken rear handle was due to them drilling a hole for mounting the saw in their test rig.
I found the starter cover on e-Bay some while back and knew it would come in handy. Turns out the Titan 35/40 and the Power Mac 380 share a number of components so I was able to gather the starter parts and fuel cap I needed for this Titan 40.
I didn't take many intermediate photos, compression is good, spark is good, needed the fuel pump diaphragm replaced, that was about it.
Makes me wonder if they were making some kind of extended run with fuel from another source?
Here it is cleaned up and back together. Started on the 5th pull, still needs a bit of tuning and I need to find a screw for the chain tension adjust. I will probably put a NOS bar on it when I put it on the shelf for display.

My "hot rod" 10-10 doing what it does in 20" red oak!
Thanks Mark, maybe I’ll just stick to my C series Homelite and the 100CC plus 1050’s, 2100, etc.

I dont have a picture of the piston, sorry. And yes, that is one of 2 black top 10-10s I own. I call this one my "hot rod" because it just flat out rips.
See my video for reference lol
It goes very well I'm impressed hard nose bar and all. I was only after the pic so I can determine if mine are thick or thin
Thanks Jethro, I wish I had all of the Macs from when my Dad first went into business. From the early 50’s to the early 70’s he had all Macs. When I started working for him in 72 he’d gone to Homlites. I remember Big Macs sitting in our barn for years. I’d go get one and get it running, then a while later I’d get another one going. Went down to the barn one time and they were all gone. Dad gave the whole pile to one of my cousins for Kart motors.
Aw that's real sad I rather see them left as a saw plenty of other engines go better in a kart

Looks like I need to get back into the carb on the 7-10. Made a new idle speed screw for it. Fired it up, revved it a couple of times just to warm it up, then it started sputtering and died and wouldnt restart. Fuel running out of the muffler. I think the needle stuck open.
I've about had it with this thing! I've put more into this saw than any other saw in my collection, I did it all "right" with all NOS or OE parts and it still refuses to run right! If I didnt have so much in it I would ship it off to someone who might have better luck with it than me.

Oh, and to add insult to injury, I've messed with the idle speed screw so much that now the threads in the airbox are getting sloppy and it wont hold a setting[emoji35]
Maybe I should just put it back on the shelf for another year!

Yeah, looking back I’d like to have them, but back then they were just scrap metal taking up room in the barn. What I’d really like is to just know what models he had. Dad retired in 86-87 and I had all of his Homelite from the 70’s-80’s. My Dad passed in 2004, about 6 months later my mom called and said she sold the house and was moving into a smaller place she could keep up. She was a little OCD when it came to doing things. She was having a big yard sale to get rid of Dads tractors and yard equipment. She gave one days notice, and I was leaving on vacation in two days. I threw a major temper tantrum and sold all of Dads Homelites except his Super 1050’s. Now I’ve been ten years trying to put the collection back together.
On my buddy’s Pro 10-10, there is a threaded stud on the clutch cover. It looks like there is a piece of cover missing. Is there supposed to be a cover that goes over the bar studs and nuts. At first I thought it was one of those gizmos you screw a rod in to measure firewood. But, it looks like there is stuff there that should be covered.
