McCulloch Chain Saws

Too much HP. Or metal fatigue, I would guess. Ron

What a weak, wimpy saw that is. No power, and no compression. BroncoRN will be terribly disappointed in it I'm sure....:jester:



Man that's a beast. Didn't even slow down when it started cutting into the two bottom logs under the single. Good job Joey!


I'm not surprised that it pulled 3/8-8 so well in that wood. My high hours SP-81 still runs a 32" bar (with a 3/8-7 rim) burried in Maple just fine. Your video makes me wanna rebuild my second SP-81 (roached and locked up) with the NOS parts now sitting on a shelf in the bedroom.


If that's the same clutch that was on the saw when BroncoRN got it from that ebay *******, then who knows what sort of abuse it'd been through. Not surprising that the spider/hub failed. Glad that you and the saw weren't harmed.

Mark, if your muffler body is an 850 (5 sided) then I have this if you need it:

View attachment 245683


The plate is thick so a little sanding will make it as new. The reed I assume can be flipped; it is now flush with the stop instead of flush with the plate. The reed stop is rough (it has the look of chain rash) but you can make it work. A new reed stop is available: McCULLOCH SUPER PRO 81, 81E, 80, PRO MAC850 NEW STOP REED PN 87193 | eBay

I don't know about you as a veteran collector but I find myself equating everything to the cost of a "new" used saw so I tend to think a $50 muffler is expensive when I have $100 in the rest of the saw. This CAD is bad bad bad stuff; I take the family to dinner, get the check and instantly think I hope they enjoyed it as a couple more meals like that and I could have bought another saw. Ron

I need a handle bar for one of these little saws. I keep forgetting it but this pic reminded me. Anyone have one?

WOW Joey, that saw's a beast!

Nice work, indeed!

It's a Power Mac 6 "World's Lightest Chainsaw".

Just don't remove the large capscrew on the front of the saw. That's the evil plug. Later mini-mac saws don't have this feature, and consequently their evil is free to escape and ruin your whole day.....:cool2:

Teach me some tricks of the trade, please.

1) How do you detach the coil from the laminated frame? Is it just epoxied at the back? I am working on my SP70 project. The SP70 coil mount is different from the 700 electronic coil but the frame has the same dimensions.

2) I have never used JB Weld. I have two flywheel cover 10/24 screw holes stripped on my 805 project. I can get to both the front and back of the holes. I know I have to clean the surface. But do I drill the holes out any larger, or just stuff them full of JB Weld from the back side and re-drill and tap them after the JB Weld cures?

Thanks, Ron

Sometimes the coil is retained with a spring or wire clip. Other times it's just a friction fit, or has a bit of epoxy or other adhesive holding it in place. Can't remember which method was used on the 10-series coils. Sorry I'm not much help...

is there enough metal to use a heli-coil on the stripped threads?

The bosses are not very big. I don't know. Ron

 

[paccity]

It's a Power Mac 6 "World's Lightest Chainsaw".

The one I have is not attached to the bottom in any way.

 

[rwoods]

Don't forget that some came with tube handles instead of the banana. Ron

Well, I see you don't need the tube version.

Sending PM......

This saw is one for my grandson.......

This one is a little too large.

Thanks Ron, I will try to put that saw in some wood tomorrow and figure out where to go from here. $50 is a lot for a muffler but I don't have too much in this project so far and could stand a little outlay. I shall report back.

MMInd - I have two or three NOS handle kits for the Power Mac 6, one original banana type and a couple of the later 1/2 wrap type. PM me if you are interested and I can shoot you a price. These came in my big haul some weeks back and I did pay a tad for the whole lot so I need to recover a little something for them.
