Title: Partner P100 Super
Post by: Modifiedmark on August 27, 2011, 10:03:38 pm
Thought you guys would like to see the big Partner that found its way here.

Its in nice shape and runs like new.

I've looked at them and looked over a Adam Clarke built piped one. I'v just never pulled the trigger on the ones I have been offered in trades and to buy pretty dang cheap.

 I think I have ran a stock one that was for sale in Pa a few years back at a gtg.  Al was there maybe he ran it too.
So much going on with the race stuff back then I didnt log it in my brain how it did.

So what do you feel they compare too in a 100cc saw?

Those things never show up then all the sudden over in Pa about 5 or more were there .They seemed to run okay but I don't think quite as well as a 2100 Husky which is exactly the same 99 cc's .

The one Adam did up was like rope starting a Harley .We couldn't get it to fire that day for some reason .Evidently there was  a wire pinched or disconnected .With the hub hub of activites I failed to find the problem and Wojo had to go on a service call someplace in Ohio so he had to boogie  before we figured it out .

I would have liked to have seen what the thing had though .Adam as usual did a fantastic job on the mods .

Another thing you have to remember is that cut times over cants doesn't  really mean that much .I imagine a stock P100 or 2100 Husky for that matter will cut in the 10's .

Now in the woods that means very little especialy in the large wood these things were designed to run in .You get into stuff 24-30 inches and bigger that's were that larger displacement gets-er-done .

I had tested the P100 in that oak log you were sitting on Al. The one you kept chewing up during the day.

I new better then to put it in a racing cant.  ;)

Now that big old petrified log was a tough nut to crack .If ye olde saw could chew through that thing there wouldn't be any thing on the planet it couldn't saw .Something like that is a good test . Seperates the race horses from the Clydesdales .

That thing had grain going 40 different directions ,just one big knot .

One of the guys from Va had a chain he wanted to test on a saw with some torque so he ran it on my Sp 81 Mac .Whatever he did to it worked out fine because under power with a saw that really didn't lose RPMS like some racers . It kept on chewing out big chips .Done good with the file .

Al, these P-100 run good, there no slouch. I had a Husky 1100 a short time back and let it go but the P-100 would have hung right with it I suppose.

I do like the way the P-100 is built compared to the Husky though. Not knocking the Husky, just like some things about the Partner better. I also just picked up a Mac PM1000 which is a relabeled Patner P100.

I'll post a picture of it as well.

They came along too late in the game to ever be a player here .Plus the fact this is not really big timber country with the exception of the big oaks .

Fact after the reign of the reed valves about the largest Mac to be seen would have been the sp 81 or 850 and those rarely .

Partner in general was never a player here .Nothing wrong with the saws except no dealers .

Trying to help someone out with some research.

Looking for pics of pistons and cylinders for the P100 and P100 super.

I bought a brandnew P100 super and gave it to a guy that was started a museum  for chainsaw , I know in Quebec there are quite a few of them running in the 104cc pipe class and they do very well

They weren't even McCullochs . ;D

By the time the board of directors of McCulloch motors get thier heads out of their behinds and offered some higher displacement piston ported saws the game was pretty much over .

I mean I collect a few and all that but the last of the professional grade of Macs were not anything to write home about .Couldn't  keep the dang chrome in the cylinders .They'd have been better off to have stayed with die cast in place cast iron liners that never wore out .--just history now ---

That was my point!  ;D

As you surely know, those Partners were rebranded as Jonsereds 1020, as well as McCullochs.

 I knew that model was sold under a number of names but I didn't know J-Red sold it too .

Rambling on it's kind of interesting how they tried to spoof everyone with model numbers and colors over the same saw .Nothing new I guess and still done .Mazda and Ford do it all the time  as well as others.

Hey Kevin, I bought this saw yesterday, any chance this could be the saw Adam built?

If I recall correctly the one Adam Clark built for Wojo had a different coil than in the picture .I have no idea what became of that saw or Wojo for that matter .The last I saw either one was over near Meadville Pa .

Scott didn't have a short bar to fit it so I took along both a Husqvarna bar and a McCulloch 16 inch bar but we couldn't get the thing started .Evidently unknown to us one of the coil wires was shorted out .I heard later they got it running which it did good .Damned thing was about like rope starting a Harley .I didn't get a picture of it but maybe someone did .

Yeah, this saw has ties to Ohio, but I think may have come from out state, IIRC Wojo lived right nearby me.....

I dont recall what that one looked like at all that Adam built for wojo back then. Think that NWPA gtg was 2010.  Last I saw of it.

Post by: Al Smith on June 22, 2018, 04:38:37 am
Since this thread was started I now have two of this model .One is running although it needs a set of rings .The other is a work in progress .
Title: Re: Partner P100 Super
Post by: Al Smith on January 17, 2020, 02:57:38 pm
It's been a year and a half and I'm kind of slow of late .I think in that time I've got all the parts rounded up including another totally intact crankcase with the rotating assembly to finish two saws from three crankcases .Two sets of piston rings are in transit as I type .
By doing a lot of research I found the sizes for the seals which are relatively common metric size .I don't think I need bearings.I even found the original nut that holds the top cover on which surprised me .The P100 Partner/McCulloch SP 1000  was never a popular saw  in these parts so parts locally are non existent .I've resurrected a lot of saws from the dead pile but these two have been the most challenging so far .These saws in 1983 were upwards of $700 so it most likely was prohibitive for  the normal chainsaw user .Plus the size as 100 cc saws just didn't get used in that time period except by loggers and this is not high impact  logging ,corn fields as far as the eye can see .
I did manage to find an original factory manual from another web forum with parts lists and information on Partner chainsaws and cut off saws .At least I'm not totally flying blind which I often have to do .I always get it but it might take  time to figure out .
Title: Re: Partner P100 Super
Post by: Al Smith on February 08, 2020, 11:15:31 am
I might point out to those interested the P-100 is almost the same as the Partner K1200 concrete saw .In this area Partner was not a front runner on chainsaws but they were a very popular concrete saw .Finding parts has been a problem using the older Partner numbers but since Husqvarna took over if you insert the Husky numbers you can find them .For example just recently I thought perhaps new piston pin bearings might be a good idea .On a search on the net from online suppliers they wanted 40 bucks a pop for them but a search on flea bay I have two in transit at 12 a pop with free shipping using the Husqvarna part numbers .Some times if you are lucky there is more than one way to skin the same cat . ;D
Title: Re: Partner P100 Super
Post by: 3000 FPS on February 08, 2020, 09:00:37 pm
So then are there any of the Husqvarna concrete saws that are the same as the P-100.
Title: Re: Partner P100 Super
Post by: Al Smith on February 15, 2020, 07:41:46 pm
I'm not exactly sure although some of them use basically the same model numbers .For example K1200 Partner .While I have the Partner and McCulloch parts numbers the only way I know is what I find on the internet .I don't have anything that covers Husqvarna concrete saws .Believe me I've spent hours trying to get info on these things .

Old thread but after all this time and now retired nearly two years I've finally started the rebuild on two. Mac 1000 /Partner P100's One will be in McCulloch trim the other Partner .I've got all the parts I think unless one coil is bad which I don't know plus  the seals .Partner IPL's are most screwed up I've ever seen .I found an IPL in English   thank goodness and cross referenced the seals with CR .
One was stuck tighter than a bulls butt at fly time,I had to pop it loose with a grease gun .The cylinder looks nearly  new and rings are stuck which might take a torch to pop them loose .It's in a bucket full of kerosene at the moment
The first will be a good lower end I found with the cylinder and piston from the one that stuck one .The one I have running will be the crankcase of the stuck one with good parts from the runner plus new rings and seals of course .The runner is a dog,I can out run it with a souped up Stihl 038 Magnum .Something wrong with that 72 cc up against 99 cc. I do fairly well with modifications but not that good . ;D

Post by: Al Smith on July 18, 2020, 08:31:42 pm
The saga goes on but I'm learning a lot about this model .For example it seems they  use two types of coils .A one piece and a thyrister trigger type .Both are next impossible to find .They both use two different mounts and as nearly as I can tell the later one piece was used on the McCulloch model .That one I know works because I had it on a running model ,not sure about the two piece unit but I will in a day or two.
The one piece is a typical two pole coil but none I have fit  the mounting bracket .If I have a failure I might try a 372 Husky coil which is cheap for an after market coil .I certainly do not want a concrete saw coil which limits the speed to under 6,000 RPM's .Good heavens I've got 60 year old gear drives that will run nearly that fast.These things are  99 cc,I want these things to run like the wind not a snail .
Title: Re: Partner P100 Super
Post by: Al Smith on August 04, 2020, 12:47:53 am
Update on this saga that has stretched over several years . I did use  a 272 Husky coil which works very well ,nice not spark .These things are pretty torquey but at 99 cc's they should be . I don't think they have the grunt of a 2100 husky though .
As I might have mentioned if you use Husqvarna 2100 bar plates a Husky bar will fit .If you are lucky enough to find the actual McCulloch 1000 bar plates a Mac 10 series will fit but you have to use a gasket to block the oil from going in one hole straight through because of the way a 10 series bar is made .Oils through the same hole as the tightener goes into on the reverse (top ) side .
From what I see on these things the main difference between the Partner P-100 Super and the Mac 1000 is a handle brace on the former to prevent breaking the rear handle should it get dropped .Everthing thing else is identical,carb,cylinder etc .
It's been a real challenge resurrecting these two .More so than any other saw I've worked on including sleeving a Mac 125 with a cast iron cylinder liner .

Post by: Al Smith on August 21, 2020, 07:57:38 am
An update on this project that has stretched over a two year period .I've been using these two saws to cut down to size a huge pile of oak to size to split .One saw I have a 20" bar and for 99 cc that is childs play .It's  got some power and it's not even broken in yet and I never touched the carb after a rebuild and that doesn't happen that often .
After a few days at it I'm now into 24 and 30" stuff so I'll break out the other with a 24" Husqvarna bar and probably have to fiddle with the  carb setting on that one .Although I've not really compared the two against a 2100 Husqvarna I'd still give the Husky an edge although it's real close .
Title: Re: Partner P100 Super
Post by: Al Smith on September 07, 2020, 07:41:00 am
A little up date .I did in fact get both saws running well .Used the coil from a 272 Husqvarna on one that had a two piece ignition .If you can even find the two piece unit they want a bloody fortune .The after market coil cost me around 12-15 bucks and has a very hot spark .
I've heard people talk about these and the P-85 blowing a lot of smoke .I found the problem being the O-ring on the oil pump shaft which both models use .That size is 5 MM by 1.75 cross section .A bag of 25 cost me 6 bucks,cheap .That fixed the problem .
As far as performance from my perspective they are on a par with a Stihl 066 .Could be up there with a 2100 Husky maybe .Makes no difference they have plenty of power .Fact I'm running 8 pins on both of them .
The only difference I've found if I haven't already mentioned it is the suspension system .The McCulloch which could be a year or two older does not have the bar running down the starter side like the later p-100 super .
Evidently this was added to beef up the handles because if dropped it could break the mounting tabs off the crankcase .Other that that every thing else appears to be exactly  the same except of course the ignition coil .
If I can figure out how to get the pixel size smaller I'll post some pictures .I still haven't mastered  Win 10 on how to do things --old dog new trick thing .

If this works this one was stuck tight .Believe it or not I saved it .The cylinder and piston went on another crankcase rotating  assembly .New rings seals etc

This is the pair of them P100 Super version to the left ,Mac 1000 right .I'll most likely doll up the Super with a paint job and decals .Both saws have plenty of power so I don't think I'll do any hot rodding to them .I did however pull the spark screens which sat inside the muffler .
