Jonsered Set-up

[eric_271]

Saw troll eyolfs post states the same thing I have been saying. There were more then one part number for the jug on the 670. Im glad you brought that up. Now can you post a picture of your 92 93 Jonsered brochure? The cover and the page with the specs? The specs in my 92-93 brochure dont show what you say yours does. This we dont agree on.

 

[eric_271]

Maybe the open port 670 you are referring to was the non-super/non-champ 670, which was listed at 3.3 kw (4.5 hp)?

That looks like it to me. I dont have a program to down size my pics except e-mail. I took pictures of my 92-93 brochure, cover and page with the specs. I will e-mail them so you can see they were not detuned in 92-93 atleast here in the states. You can post them here if you like.

SawTroll My last ? Were the championships won with the 3.3kw open port or the closed port 3.6kw 670? You should know this, it is the same thing I have been saying.

Sorry, it is a paper copy, and I do not have the equipment to post it.

Mine is the Norwegian Jred catalog, and I suspect yours is the US version.

Over the years it has freqvently happened that model and spesification changes has taken part at different times, at different markets.....
....it could be as simple as that.

All things considered, I think it was the 3.6 kw 670 Super, but I don't really know. I also suspect that 1987 was the year this version was introduced, as it probably was very similar to the 268xp internally. I don't know when it was renamed the Champ.

By the way, I have never stated (I think) that the non-Super/Champ was open ported. I tink it was very similar to the 266xp........

 

[eric_271]

SawTroll the super or champ as it was later renamed was the saw that won the championships. Scroll back up a few post and you will see where you called the non super non champ an open port 670. I think you hit the nail on the head when you said that. A saw builder told me the same thing years ago. We already know from past post that there were different part numbers listed for the 670s on the cylinder and piston. That makes sense. To start with it was called 670 with year built and specs and that was the lower hp version. I have learned from you and this I dident know, is the super was around 2 or 3 years sooner then I knew of, 88 or after. eyolf stated an open port part no. same cc as the 670. Im speculateing here thats what the lower hp 670 started its life as. I have no information as to when the super came along by date other then in 88 like you stated when it won its first championship. I do have a date on the lower hp version 87. To me that says this saw started out as '' 670'' then followed by super and champ both haveing higher hp then the plain 670. What do you think?

 

[SawTroll]

I am quite sure (but not 100%) that the "plain" 670 and the Super/Champ both were in the lineup for some years, from about 1987, but I am not able to prove it.
CSCC states that the plain 670 was in the lineup from 86 to 97, but for several reasons I doubt that it is correct. Logically it should have been introduced earlier (about 1981/82, as the 266, 162 and 630), and also discontinued earlier.
I have reason to believe that the Super/Champ was introduced about 1987, as was the 268xp, and I have an IPL dated as late as 1999, covering the 670 Champ and the 625 II.

But what do I really know, facts are scarce and rumors and opinions plentiful.

 

[eric_271]

It is 100% sure it was and still is a fine saw.

 

[SawTroll]

This sure has been fun, but by now I think we have run out of both facts and more or less educated guesses!
:Eye: :Eye: Anyone out there with some hard facts????

 

[Chris J.]

I can tell you that some parts between the different 670s don't interchange, and that depending on which 625/670 IPL you have you'll find different part numbers. I have a running 670 (don't know if it's a plain, a Super, or a Champ), and two parts 670s, one of which is a Champ. Oh yes, if you have a source for the air filter cover (still available, but not cheap) and the clutch side cover (NLA & definately not cheap), you might want to buy a couple of extras.

Eric, I din't realize that you were a 670 expert . I probably have enough good parts to put together another 670. In fact I recently received another complete parts saw, but it might be a 625 or 630. I haven't yet started tearing it down & cleaning it up.

 

[eric_271]

Chris I bought mine new in 92 or 93 . It still looks like new and if anything runs better then new. Thats not to say I havent worked the piss out of it or it out of me but I never waited for things to get bad be for I replaced them. I trust you are saveing everything you have so when I do need parts they will be at my disposel?

 

[Mange]

I was told by Ulf Näslund that the 670 is the HVA 266, so that is now confirmed.
A better source regarding HVA's is hard to get, he is behind most models in one way or the other.

 

[eric_271]

Mange is he saying the 3.3 kw 670 was the 266? If so what did the 3.6 kw champ match up with?

 

[Mange]

He said I quote:
"The 670 is the same as the 266, I am not sure what is different in the models, but they are the same saw."

I will try to contact someone that was at Jonsered at the time, we will se what he thinks.

 

[eric_271]

LOL Mange I know they are the same saw to an extent, but there were no 266s rated at 3.6kw. What gives?

 

[Mange]

[eric_271]

Mange This is the story I just got. Slight port timeing differance from the factory between 670 and 670 super. You can use the piston from the 266 in the 670 but thats it unless you change the whole piston and jug asembly. They are different where the carbs bolt on. The 670 and 670 super are both closed port, but again are not a 266. Lets see if any of this jives with the jonsered guy. By the time we get this hashed out we will have written a book. May-be Jonsered could pay us something for our trouble.

 

[Mange]

If you can use the same piston both is open or closed. otherwise the pistons would not be the same right.

The 266 I have I will look at it tomorrow, to see if it has open or closed ports.

 

[Mange]

Troubble......
I do this for fun.

 

[eric_271]

Mange I think the 266 is closed. I just got an e-mail back from a second guy that has new old stock 266 and 670 Champ. He said he put them side by side to compare and says they are not a match. Thats not saws, thats jugs. eyolf stated his part no. on the 266 as closed.
