help I.D. an old Jonsered

[John in MA]

You see on yours how there's a bracket with the mounts on the clutch side of the handlebar, then the mounts on the trigger grip? Mine has all the handles bolted directly to the fuel/oil tank, then the tank is AV'd to the crankcase. The crankcase sits like a saddle over the tank. I haven't seen any other old Jonsereds use that scheme.

I wish the 801 and the 111S shared handlebards. I'd love a full-wrap--I don't use it much and I want all the control I can get with this thing.

After I get the bar stud thing fixed, I will check with george on handle.
My main reason for not wanting the full wrap is for use with the alaskan mill. I have to get a half wrap for my 372, but Baily's has that for $20

Just weighrd the saw, it came in at 15.75 lbs. Do you guys think we are certain to call it a model 80????. Anyone with an ipl for the saw? Thanks everyone Bob

 

[bob gresko]

Sorry, I want to make my last post clear. The saw weighed 15.75 lbs power head only. sorry fellows

Bob , my 80 looks just like your saw and weighs 21 lbs with a 19" bar & chain . It sits about 8 5/8" high if you measure it from a flat surface ( center of the starter housing) to the high point of the cover . I know a 621 has alot lower profile and a 111 has a much bigger one . I think someone said in an earlier post that a 621 has the kill switch on the right side of the aircleaner . It sure looks like an 80 to me . And not to pi$$ off the "non-users", but mine both read over 200# compression cold . Some people can't relate but it will snap off the starter handles when you turn them off !!! And you better think positive when you start em up . Jon

Looks a lot like an 80, I am attempting to attach a photo of an 80
The weight is correct at 15.75 lbs

The 621 had two triggers. One acted as the interlock. Also, the 621 air filter cover was flat on the bottom. The rear handle lower mount on the 621 was fastened on the "outside" of the handle.

There is no doubt whatsoever, this is a Jonsereds 80.

I have an Illustrated parts list that I would be happy to copy for you. I also have any, and all parts for this model, both new, and used. If interested, contact me at: [email protected]

All you guys, thanks for the info. Before I found this site, I only used a chainsaw for cutting my own firewood, and occasonially cutting trees on building lots. I am a builder by trade, not a logger or small engine expert. However, this site is beginning to turn me into a chainsaw junkie -- I love it. So here is my next question -- this old 80 needs points, condensor, filters, muffler, etc. What are everone's thoughts on rebuilding it and supercharging it. It sure seems to have lots of compression - about 10 years ago I had to tap oversized screw holes in the starter cord assembly because the origional screws stripped out of the housing because of the hard force required to pull the cord. Is it possible to install a compression release valve? I'm game for tearing it down to bare-bones. What would you guys do with it if time wasn't a factor in getting it back on the road?

 

[sedanman]

Not a saw I personally would hot-rod. Parts for older Jonsereds saws are not readily available (generally, motorsag is the exception). Get a new saw for that, the builders like it better that way too. As for a compression release, this is possible but you'll have to get the cylinder off and have it machined. A Stihl elastostart rope and handle WILL make the saw less punishing to start, this is what I would try before resorting to machine work.

I could not find the 80 IPL on the Jonsered CD ROM.

I have never seen 80. Back when I was selling Jonsereds the first time about 1982, the 70E was the biggest I stocked. I also has Husky and Partner at the same time. None of them had a lot of name recognition then, but the Jonsereds name was lot harder to sell than it is today.

 

[Whistler]

Bob , I wouldn't have any idea of the cost of putting in a compression release button but I have replaced worn out 80 cylinder/pistons with the 910 jonsereds cylinder/piston . With some luck you may find some obsolete units sitting on some shelf at an old jonse dealers . They do bolt right on . The last one I bought was about $160 almost 20 years ago and I still think it was worth every penny as it is a very strong saw . Let me know how you make out if you decide to go that route , but always check with Dennis Greffard first for deals on old parts . He sure has done me right in the past . Jon

 

[John in MA]

Sedanman has the right idea. These are old saws with little parts support. Many of them (the model 80-types in particular) seem to have been designed pretty close to the edge, anyway. Enjoy what you have.

 

[Whistler]

Bob , if that unit pukes , you let me know as I have some stuff lying around here to keep her alive if you see fit . But on another note , they really do vibrate , probably worse than anything Iv'e ever run . It is a sentimental thing ......Jon

 

[NWlogger]

That looks almost exactly like mine except that mine has a compression release on the top right side of sparky.....and a square air filter housing. Mines a model 90

[motorsag]

That is without question, an old Jonsereds 80. The 621 used two (2) triggers (one as the interlock), the 80 had the interlock at the top of the rear handle, and had only one trigger. The 621 air filter cover was flat on the bottom while the 80 used a completely round cover, as in the picture. This is an 80.

I have the parts list and most any part you will need for this saw.

Nice to see you posting, George. I think this is an old tread that has been bounced up.
However you were correct then, as now, as always

To NW Logger...

I'm working on a Jred 90, & I have a nearly complete parts saw-it's possible that I could wind up with 2 running 90s. Can you/would you please post some photos of your 90 with the decompression valve? I need all of the help that I can get, & I would really be thankful for the photos.
