Jonsered Chainsaws

[Cantdog]

The worst mag rot I ever saw was on a 70's Partner that was stored on the floor of a milkhouse on a dairy farm. The floor was always wet and they use an acid cleaner for the pipeline milking system that was also always present. The saw came to me with the complaint of "the cord won't pull". I guess it wouldn't. The whole bottom of the saw was gone. It looked like one of those factory cutaway displays. On top of that the crank was rusted solid. I wish I had a picture of it, but this was way back in the olden days before I owned a camera.

LOL!! I picked up a 910E off ebay a couple years ago.......looked pretty decent in the pics., no kind of rot showing....I was looking for plastic parts and rear AV mounts. Price was right. The add said it would turn over but was very hard to do......holy cow!! It arrived and sure enough I could just barely pull the cord at all. Pulled the recoil and there were fresh beat marks on the flywheel where a couple fins were missing...looked like someone had been beating on the flywheel with a punch to get it the crank to move...WTH?......so I opened the fuel tank and this ooze came out that looked like cottage cheese......I put the cap right back on and it hasn't been removed since. The saw looked in great shape but I suspect it had been in one of those homes/garages you see on TV with just the top of the ridge showing above the flood waters......You wouldn't think that would be an issue in Arizona but I lived there a couple winters in the 70's and when it rains flooding is rampant. I remember in Jan '79 it rained for three days and washed most of the junkyards in South Phoenix away.......I remember riding my motorcycle out towards Wickenburg (60 miles away) a month or so later and seeing cars strewn along a wash (dry riverbed) with one car like '62 Rambler station wagon buried nose down in the ground to about halfway up the rear doors with just the back 4-5 feet of the car sticking out....rear wheels about 2 feet off the ground!! So I guess it is possible the 910 had been in a flood. I left no feedback.....though I got what I needed from the deal at a fair price I felt the seller could have disclosed the fact that the saw was to never be started again.

Here you go Kevin..........no where near as bad as Eric described but pretty crusty none the less. You can see why I haven't any interest in putting much onto this saw as I have way better lower end/case examples to build a new saw on. I'm pretty sure I will upgrade to the 90 top end....I like the idea of the decomp and 10 more ccs doesn't hurt either if you wanna build a "go-faster"...just stuff kicking around...might as well use 'em. There are plenty of good parts on this unit that it can donate too. I am going to have another go at getting this one running again just to get a feel for the pipe....have no idea whether or not it was/is tuned to this saw......think I'm going upload some intelligence before I can even make an educated decision about it. But if I can get this thing running decent I can tell the performance difference between the pipe and a regular muffler on an otherwise stock 80.

Need a poster of that will the caption: ‘Don’t be a dumb-a** and do this to your saw!’

Wow.......

Holy cow......I see what you’re talking about!! Yes, I’d bail on that puppy too. Bin all the useful parts.

I talked in here once about an 80 I bought on eBay that had been under water. Ad said ‘had compression’. Yeah, felt like it had compression because the crank was full of water and sediment. I gave him a bad rating and explained why. He was plenty pissed.

I binned all the useful parts.....think I paid $50 for the saw.

Wow.....wonder if he found it in the same river my 'watered' 80 came from...lol!

[Real1shepherd]

Not even a bid on the 'underwater' diving saw.....lol!

A little off-topic, but I wanted to make Kevin drool a little..............................

 

[Real1shepherd]

Oh la la....did you just pick this up, Eric??

Nice, nice shape....and I'd be tossing the chain brake clutch cover away....lol!

This is one of those saws that I have known about for a long time, was never sure if I'd get the chance, but patience paid off. The local high school vocational dept. bought this saw new and was used for some kind of a competition for one year. My cousin bought all the saws from the school, mostly Jonsered 630/670, that he used logging. He only used this saw a handful of times as it was bigger and heavier than he ever needed. It has been on a shelf in the shop for years. I first noticed it in the early '90's when I was working on his brothers farm. I first realized what it was about 15 years ago. I first inquired about it 10 years ago. I made an offer about 4 years ago. He asked me if I was still interested about a month ago and I finally got my hands on it last night. Since I was buying this from family I paid him a very fair price (actually the most I've ever paid for a used saw). It will live on my top shelf, sitting next to my Jonsereds 111s and Partner P100. It completes my "Big Swedes" collection.

Great story, Eric. I’m always a sucker for a good provenance tale and this one was a long time in the making!

It has that look of a low hr saw fer sure. 2101’s have the updated ‘spring’ AV on the bottom. A lot of arguing about what the XP designation meant back then. I had a rep tell me back in the day what it meant. I mentioned that on a Husky thread and some member tore into me saying all regional reps were notorious liars and scalawags.

I tend to steer away from those threads these days.

Awesome Eric!! At a much lower level I've P 100 that is very close to my shop.....a widow that just wants it gone for $100.....very light use....Gotta grab that before she leaves for the winter.....

 

[fossil]

I' surprised you guys didn't know that XP stands for "Exrtra Potatoes" and there's lots of them in those saws.

I got my P100 through a local dealer from a long time tree professional customer of his. He was in his eighties and decided he didn't need it anymore. I got to chat with him and basically hear the whole life of the saw.

I got my 111s through a trade with a very reputable dealer and site member at a gtg several years back. He got it from a older man who bought it new for his firewood because he had to have the biggest saw. I think it was traded in on a 455 rancher.

The funny thing is all three of these "big three" came to me with 20" bars. The P100 and 111s both wear 36 inchers now. I spent so much on the 2101 that I have to wait for a good deal on a long bar for it. Patience...........................

 

[fossil]

Same up here. The 20" bar is king from 46cc to 100cc. Go figure. Maybe it was the big diick thing.

 

[Real1shepherd]

Yeah, Tim and I were just talking about big cc saws and small bars.

I love big cc saws to use, but I’m always looking for the appropriate timber for them. Otherwise, I’ll use a smaller saw.

A guy that always has to use a big cc saw no matter what is suspect in my book.

And the big d*ck thing is true....I always had any number of nimrods eager to buy my 2100 at the end of the season. You couldn’t tell them anything....their eyes were as big as the saw.....lol.

I tried not to think about it....hopefully the saws broke down on them before they killed themselves.

Kevin

 

[Zero_sum]

Yup, my 111 had a 20" 404 bar that came with it as well lol.

Another thing 'profound' about the 111S is that I think most of them, if not all, left the factory with spur drive sprockets. Oregon fixed that bungle almost immediately, but still......

Some years ago I was told that there is less power lost from a spur than a rim sprocket and that they were a better option on big saws with loads of torque...

Maybe on paper to an engineer, but in actual hard use the chain wears way into the spur and causes all kinds of problems (excessive wear on drive links)....not the least of which you have to replace the whole drum unit when worn. Whereas in a rim sprocket drive you just replace the rim. Also, since a spur drive can't float like a rim drive, your chain will come off easier when you snag it limbing. I never knew anybody in the woods who stuck with a spur drive.

What's favored in timed competition, I have no idea.
