jonsored question??

[johnb]

How long did they make the 670?? I have a 670 that requires a major and just acquired a parts unit to help with the job, but after contacting the local dealer they said some of the saw may not be compatable. They related that the 670 was changed over a few years. Do any of you knowledgable jonsored guys know if this is true? And how extensive were the changes?? thanks The Hoosier

Hoosier...the 670 was made for many years, the crankcase is (someone will correct me if I am wrong) the same as the 625, 630, Husky 61, 266, and off the top of my head the 262 as well I think. Parts are very easy to come by, and the 670 was a fantastic saw.
I don't know which parts wouldn't be compatible throughout the years of the 670 as I don't recall any change(except minor like a filter change...670-670 super) I did run one for awhile but repairs and parts to them were before my time as a mechanic....but I do have lots of parts...
Make the saw work...very reliable..

Hey Dennis, what's up with the signature. You must be from B.C., are you just discovering John Denver now? Get with it, Johnny Prine is the man, get " Inspite of Ourselves", title song, from title CD.

670

I agree. The 670 was a great saw. I think it went 670, 670 super, then 670 champ. Definately the same frame as the 625 and 630 models. If it is the same as a 61 and 266 than I think it will also be the same as the 268 and 272 but I may be wrong. I can tell you that it is not the same as a 262. I used to have a 670 and they were a very torquey saw.

Will you just get "on topic" for once???????????? don't make me remove you too....

 

[Dennis]

Bdenny, you are correct in the chassis being the same as the 272 and 268...I forgot them....I do have a 272 piston and cyl sitting on a 630 frame...with a "special" crank....lol...

Since Husky parts are easyer to come by in these parts, do any of the husky pistons match the 670?? Which husky was a cc and stroke match for the 670?? I will need a piston and gaskets to complete the project.. thanks for the information The Hoosier

There were some minor changes over the years, and I'm sure Dennis knows about all of them, but there were at least two different clutches using two different sized cranks. (husky, too) Also old and new style coils. I'm not certain, but I think some 670's were pretty much identical to the 266 huskys.

All of the saws listed and a few more used the same 34mm stroke, but there were a bunch of piston/cylinder variations that went around. The 670 used a closed loop transfer port, unlike some, like the husky 268 (same displacement) that had open transfers.

I've been collecting parts myself to re-rebuild a 670. I've got a new crank, bearings, seals, etc. and a nice used Husky 272 barrel with carb. I gotta get a piston, then see if I can find somebody with a magic touch to massage the ports. Anybody know someone who does this sort of work?

The 670 is well worth restoring. Mine cuts as fast as my Jonsey 920 in wood up to 18" dia. Dont forget about modifying the muffler while you are at it.

 

[Dennis]

Eyolf, good call, I forgot about the clutch change...was thinking that was the 625/262 that did the two different cranks...the coil issue isn't too bad if you can change both the coil and flywheel together....

As Huskyman said...the 670 is well worth fixing if you have the parts...great saws!! (and they are red and black)...lol
