McCulloch Chain Saws

[Eccentric]

Such a good job I left the pics in. Now what I am going to say might shock you. I would rather have that SP81 over a Partner P100 oops I mean a PM1000. Now a SP125 would be something I could sell a SP81 for if I had more than one but if I only had 1 I would keep it. Great power to weight, parts are easily accessible, great saw that I still use as a firewood saw. The last P100 I saw was only $199 and it had been completely rebuilt.

I agree 100% on all counts Jim. I've got other 100cc class saws (REAL Macs and Homelites), and that SP-81 is a KEEPER.

i agree with you that the SP81 will be a saw that i would prefer to run over the PM1000. but i can't run two SP81's at once so i'm letting one of them go. the SP81 that i'm keeping, i've gone through it like this as well but with out the paint job. it didn't need it.

i wanted to show you guys my current project. i'm fixing this one up for sale to pay for another saw. i've got a couple of these, so i'm selling this one to pay for a PM1000. this SP81 was beat badly like a tree fell on it or somebody left it in the bed of the truck and put all the fire wood on top of it. it had some stripped screw holes and the left side cover was busted up too bad to use. it also was missing the clutch cover. i've got a picture from just about every step in the rebuild process if anyone cares to see it. you can see in the pics that some of the screws are not original on the left side cover. those are the ones that were stripped out and had to be drilled and tapped a size larger. everything was reassembled using blue lock tite so the only thing that comes loose is the fillings in your teeth.

So far, i've installed a new intake boot, new front and rear AV mounts, new carb kit, new fuel line, new fuel filter. i checked the points and lamination gap, i also pulled the piston and cleaned the carbon from the chamber and piston. the cranks seals held 10psi without bubbling. (I didn't push it any further than that). its also got a later mcculloch bar with sprocket nose, its a laminated bar but it will do. the bar is 20" and i just installed a new 3/8-8 tooth sprocket. this saw has the dual adjustment carb and an almost new air filter. the paint job is kinda crappy, it just takes too long to sand one completely down. but the paint looks better than the flakey paint that was on it before. compression is too stout to test, my fingers can't take that abuse. as soon as that cover arrives that Ron is sending, i'll test it out and make a video.

That saw turned out GREAT. PLEASE post the build pics. What black paint did you use? I'll probably repaint the tank/rear handle, AF cover, and starter cover on my SP-81 as they're pretty beat and 'flakey'. If I somehow stumble upon another SP-81, you can bet your bottom dollar that I'll keep it. If I am that lucky, I may set up one with a 3/8-8 rim (or maybe even 3/8-9) and a 20" sprocket or roller nose bar for fun zipping through cants at GTGs. My current saw has a 32" Windsor sprocket tip on it now, and also has a 28" RN (OEM on the saw) that I'm going to fix up. I have an NOS piston/cylinder/oil tank replacement parts "set" (packaged that way by McCulloch) for SP81/PM850 saws. I'm keeping it safely in my closet...........................either to keep my current SP-81 running for a LONG time to come, or to refresh a burnt out (and therefore cheap) SP-81/PM850 that comes my way.

What about dual wield? One in each hand. The SP81 is a great saw and I should have looked at your signature, I see no PM1000 down there so I guess it would be ok.

Dang it!!! here we go again. i was trying to fight the disease and sell a saw to buy another. now with the way you guys are talking i'll end up changing my mind and keeping it. a week or so ago i was going to trade this saw for a 101AA, which might still be an option. oh crap, too many decisions. :help:

 

[joeymt33]

just wait until you guys find out i put a Mac 4300 up for sale on feebay. it was another duplicate, but i'll be scorned for that too i'm sure. :eek2: its all with good intent though, sell the ones i have doubles of to pay for those i NEED.

 

[MEATSAW]

Well first off, I need to apologize for being a complete *******. I went back out to check things out on the carb that's on my saw and surprise! The carb is a Tillotson HS-165A. Of course I don't know what that means as far as switching over to an SDC or if they even make tillotsons that are the fully adjustable variety that would fit. Time for a beer.

Here are some pics of the current carb.

Same handle on ebay as here? I have a buddy that's looking for a PM700 type saw, and a PM4300 would fit the bill nicely...

on the paint, let me say that i prefer to blast the saw and use the chemical resistant powder coat. i've only done a few saws like that though since its take alot of time to blast and bake over and over. so, this time i tried Rustoleum Professional Enamel flat black. i brushed "most" of the old paint away with a brass wire brush then i cured it with a heat lamp and it seems pretty tuff. time will tell though.

for the pics, i'll post a few.

MAN that's a clean saw! You can swap to an SDC no problem. You'll either need to use one of the integral idle speeed screw carbs (such as that SDC65) or drill and tap your carb box for the external adjustment screw (and obtain an adjustment screw). Does your carb box have the boss cast into it (though unmachined) for the adjustment screw? It would angle up from the carb box towards the throttle arm tab (or down from the tab towards the carb box.....depending on how you look at it).


I sent this to you in a PM..........but feel it'd be helpful for folks here so I'm gonna post it here. Sorry to all if I've broken any rules with he links..

Here's your IPL, in case you don't already have it.

http://www.mymowerparts.com/pdf/McC...15_600052D_7_10A_10_71_to_12_75_IPL_91123.pdf


This site is my go-to for Mac IPL's. They're organized by serial # prefix (15 in your case), followed by the model # (600052D) and the model name, date range, and IPL # (7-10A, 10-71 thru 12-75, #91123).
"K&T Parts House Lawn Mower Parts and Chain Saw & Trimmer Parts"

What's amazing is the shear VOLUME of different 7-10A IPL's. DOZENS at least. There are all kinds of variations. My 7-10A is also a 600052D, but has a 12 prefix. Same IPL # and date range, but my saw has the fully adjustable SDC44, needles that pass through the carb box (with a boot), and external idle speed adjustment. Crazy that they'd build 7-10A's during the same time that were equipped so differently...

Joeymt3, i just posted the saw yesterday and it jumped up there pretty quick. if a fellow AS member and Mac fan buys it i'll knock off the shipping.

no problems switching over, if you want that SDC65 just let me know. Did we ever get a for sure answer if it has the same diameter venturi?

I just found it in a search for PM 4300. Looks clean. I'll pass the info on to my buddy. He's an AS member and a good guy. If he bids and wins I'll let you know. That's a very generous offer.

Hello all! My younger brother, heimannm, was going to help this weekend in Newton,Iowa to help take down 95 dead or dying oak trees. One tree measured 5 foot in diameter. The rest were not quite that big but all were mature trees. Sounds like he is stuck still working so I will give you some of the details of our firewood weekend! About 12 people working at different times. One big John Deere trac hoe,two Cat skid steers with rubber tracks,one rubber tired Cat skid steer with several grapple buckets, forks and buckets. A big tandem axle dump truck, a medium sized single axel dump truck and a tonner pickup pulling a double axel dump trailer. Over seventy-five loads of firewood hauled to six different places. Much of the wood was cut up in usable lengths before it was put on the trucks. None of the wood was split other than what happened when the trees fell down. The wood came from two city parks and the trees were infected with Oak Wilt. We had maybe 15 saws to use and there were five to six going at one time. One person pretty much stayed in the enclosed trailer and sharpened chains and kept the saws running. I brought a couple of my old saws out to use, a 1-63 gear drive that was shooting a steady stream of fire out the exhaust when cutting(not the safest but impressive in a macho way) and the other cutters complained about the noise, and my 10-10 that everyone complained so much that it hurt their ears even with protection that I had to put them back in the truck and use two of my creamsicles, a 031 and 360 Pro. I have never been involved with a group cutting experience like this before and it was fantastic. My son-in-law and his friends were the owners and operators of most of the equipment and it was impressive to watch and be a part of. I swear a couple of the guys could drive finish nails with the track hoe and skid steers. We started after noon on Thursday and worked till about five each night. We finished at 4:30 Sunday evening and only the 6 in. and smaller brush and a couple of piles of sawdust (big) were left. Several of the wives made food and one morning we even had breakfast at the site. The only problem that it was maybe a little too warm and we had to battle mud in the afternoons but no one got hurt and that's the most important thing. We all probably have at least 2 years worth of wood out of this weekend of labor. I will try to get some pictures on the site soon but beer and lots of sleep sound good right now.

Too warm in Iowa? Usually in Heimannms pics there's snow in the background...

no problems switching over, if you want that SDC65 just let me know. Did we ever get a for sure answer if it has the same diameter venturi?

The venturi are all listed as 19.05mm (.75") except the 58 (17.48mm). They don't list the 22 on their site for some reason.

i didn't take pics with the motor apart, sorry. here is where i remembered to fire up the camera

new boot: notice the 7 tooth sprocket in the pic, i later changed that out for a 8 tooth

another left side cover:

new AV mounts:

 

[joeymt33]

new line and filter:

even though its messy, i sealed the fuel line, throttle adjustment, impluse line, crack case, etc with Aviation grade Form-a-Gasket. (thanks to Ted for turning me on to this product)

the kill switch wire was cut, here is the repair:

helpful carb info on the SDC's. Sean (MEATSAW) gave this web address to me. its a good one to bookmark

I would keep the SP 81 and buy the 101. That sounds like a win win to me.

Almost forgot - there is one piece that I cannot remember where it goes. Seems like it was on the bar - maybe a stand for the nose?

Looking great Dave! That piece was mounted right above the bar. I was told it's a chain catcher that was usually removed and lost.
