I hope your new job includes using a chainsaw.

I wish dam it. Got two more tree jobs coming up though. Word is getting around i can make trees go where needed. Sorta wanted to get into climbing so I can remove more residential trees but its a big big step:(

I'll see how it goes. Id love to make a living on a saw. It's peace in my head. The sound of chips on my helmet and boots the buzz of a mac it's beautiful
 
Rare, classic, antique and vintage are all words that add value.
I'm more of a sentimental person I have my Dads xl super 2 and it's not worth much but there's no money that could buy it.
I have known quite a few guys who are dead now with collections more valuable than I've seen on these forums and usually the kids or others squander them off for profit , thats kind of motivated me to give away a few saws that I have doubles of ,to those who are in need of a saw.
I always thought good saws and fast cars were wasted on the old , but the older I get the better I am at not taking things for granted.
Fyi we finally got electricity back today from Thursday.
 
So, I picked up this Super Pro 81 for $30 this afternoon... I'm not really sure if I did good on this one or not after giving it a quick closer look when I got home.

The Good:
Great compression
Air filter was relatively clean and had no holes in it
???

The Bad:
Light to moderate mag rot, mostly on the handle and bottom plate
Decompression valve appears to be stuck in the closed position, I feel like I'm going to dislocate something if I try to start the saw as-is
One of the bar studs is stripped and spins in place trying to get the nut off
A few odd/missing screws, evidence that someone was trying to muck around inside in the past and did a poor job putting it back together
Literal spider nest. I swear there's spiders coming out of the woodwork everywhere on this thing

Is this worth trying to save? I know from searching through old posts on here and other places online that mag rot can be treated successfully with a chromic/sulfuric acid mixture, but I have yet to find any sources for this chromic acid that don't cost an obscene amount of money for a tiny amount. Are there any other alternatives to this process?

You did great man. That cylinder alone
 
Jethro is right,heck the carb alone is worth more than what you paid for it.Take your time with it & it'll come together.You've got a lot of guys here who'll help you get this beauty back into shape.I'd almost kill for one of those saws.First thing you might want to do is get some insecticide & spray the thing down to get rid of the spiders.Lol Next would be to spray some lubricant on & around the DSP & see if that'll free up.I don't believe you'll break anything with the DSP stuck open,but it won't run worth a pile of beans.Check to see if you've got spark too.The filters can be had fairly cheap,so don't even give that another thought.

I see some strange fasteners in there. One option might be to disassemble the hole thing and have someone glass bead blast it to get the mag rot ,local sand blasters are usually pretty reasonable.

I'll bead blast it if you send it to me, but it might not make it back. :D
 
I gotta say this.
Life was so much simpler when I only had a XL-12 and my fathers SL-5 setting on a shelf.
I love it tho.

I spent my day yesterday on teeth, drags, gullets and bars on three saws.
Then I tore down a 10-10S I bought last week.
Both oilers were not working. I replaced the O ring on the manual oiler. I hope that will work.
Then that gas tank. Awww! I have it soaking in acetone.

Two of the screws on the muffler were loose and covered the jug with oil. A mell of a hess.
Of course I dropped one exhaust screw. I'm still looking. Ha!

This is the first Mac I've taken apart.

Thanks for looking.

My first objective with the SP81 is to get the clutch cover off so that I can remove the bar and not have it constantly be in the way.
Easier said than done though. What should I do about this bar stud situation? The nut on the left stud came off just fine, but on the right stud trying to back the nut off just makes the entire thing spin.
I thought I might be able to just unscrew the stud out, but it seems to want to stay in no matter how much it turns. Is there something else holding it in there?

Here's some other close up views of the saw showing some of the missing screws and other weirdness.

I’d clamp the tip of the stud with vice grips, bust the nut free with an open ended wrench, and then pray that the nut is loose enough that the stud won’t try to spin when you turn the nut.
 
I had this happen on a 610 & it was a nightmare.Those studs are specially hardened so you can't just cut through them with a hacksaw.I was able to get a needle nose vice grip on the stud from inside the cover,but still couldn't get the dang nut off.I think I ended up drilling it out,but ended up having to replace the tank as the stud had rounded off the inside of the tank.
Mogulmasher has the best idea to take the tank cover off & put a vise grip on the stud.You'll see why you can't just unscrew the stud once the cover is off.

Yeah , take the one screw holding the oil tank cover on and then you can get at the stud head, but I bet its a regular bolt or something.

Thats a good one, you'll really have a nice mac when you're done , fyi your life is gonna be ruined when you run it!
 
They have square heads & are held in place by the formation of the tank.
Yes that's exactly what they are "supposed" to be , but with all the other crazy Fasteners on that saw it could be a peice of all thread with a nut on the end , we won't know till the oiler tank cover is off, exciting isn't it!
