Jonsered Chainsaws

[taplinhill]

Well I got back to work on the air leak on the 670 Champ the other day. I tried running saw and spraying around cylinder base, seals, and carb boot with starting fluid. Had no affect on it. I put new crank bearings and seals on this saw. Also a clean up of ports and opened up muffler. I was searching online and found an old post from AS where someone with a Champ had identical symptoms I had. He ended up finding the pulse line loose on the carb. Well my pulse line is in beautiful shape, but did fit a little loose too. I clipped off 1/4" and refitted line to carb. The problem seems to be solved! Saw runs amazing! It feels to have power similar to stock 372s I've run.

Long live the Champ!
I've said it many times, one of the best they made and one of if not my favorite saw.

Saw definitely seems to outperform its size. Runs more like a 70cc saw.

So question for those that may know. How were the world championships this saw won conducted? Were there classes of saws or everything competed? I've heard the 670 won multiple years, thats why the Champ was named....but I really don't know what it means or exactly what it won.

I have watched those competitions for 96-97 but was unable to locate them this morning. This vid shows and example the limbing practices. There are many more parts to these competitions. These are very strict competitions.....in the actual race, when ranking the shown competition, three judges come out...one with a clip board, one with a straight edge and the other with a dial caliper. They measure any amount of a limb that sticks up and also using the straight edge, measure any depression from cutting below the surface....all this is recorded and tabulated to create a score which is then added or subtracted to their individual times. So it is not only how fast you limb but how accurate you are. The "Champ" was considered the very best power to weight ratio, cutting speed as well as it's handling characteristics for those years. The "Champ" is simply a renamed 670 Super II and was the last and best (IMHO) version of these saws. Not sure about the combustion chamber shape on the 670 Super II/"Champ" compared to the earlier 670 Super........I do know that the 630 Super II has a "D" shaped combustion chamber compared to the regular round chamber of the 630 Super ......this makes more compression, better flow and more power.

Lol....good way to cut your leg off. Just shows you how far competition gets away from real-life limbing. And in the woods you walk down the log with corks on. But this is supposed to represent limbing on some level.

I remember on a loggin' show in CO when we were in Ponderosa pine. Bosses gathered us all up and took us to the landing. Ponderosa limbing is unlike any other limbing I've ever done. The branches compress like they're made of rubber. The speed you usually achieve limbing is thrown out the window. You spend your day fighting the limbs so that your bar tip doesn't pinch.

Anyway, when we got to the landing most of our logs looked terrible with long stubs sticking out, because we hadn't trimmed close enough to the log trunks. We all caught hell for that....lol.

Can anyone identify this saw. It's coming up in an auction and the only description is Jonsered chainsaw, heated handles.
After looking at a lot of pics I think it may be a 2171 or 2172 but I'm not sure. The pics are poor.

IDK the number but it looks like a J-red 365/72 X-torque, judging by the decomp position.

 

[Cantdog]

Yep....my guess is a 2172 also.

Tim, you have enough saws now

No question about that but you only live once. Think how nice it will be at the auction to have all those saws in one place when I croak.

I doubt I will win it but it would be nice to have one just the same.
Nice to have a 372 at a bargain price that I'm willing to pay.

Gee.....did they literally dig it out of a snow bank??

Looks that way. Not the best auction house I suspect.

 

[taplinhill]

If you need another opinion, just to confirm, it's a CS2172WH.

 

[leecopland]

Did you win it Tim?

Thanks for the ID help gents!

No Lee, bidding starts this weekend and ends November 13. It will be tough as a lot of saws at auction go high these days.

The only thing that seems to go cheap are new bars. I got three power match bars and a little A041bar for $21 a few weeks ago and a 36" power match D009 bar for $25 CDN last summer.

Well today was first real test of my 670 Champ. Bucked up this entire load of decent sized cherry. Little bit of rot around the outside of some pieces,, but center was rock solid. Saw ran great! Super throttle response, handles great, and cuts fast. I couldn't be happier. Probably just became my go-to saw for most tasks.

I spent an enjoyable afternoon cutting up two wind blown maples with my 49SP. That saw continues to surprise me whenever I use it. Sorry now that I didn't take pictures of the results. Great firewood for my good buddy Jim.

 

[Cantdog]

IMHO......a 49sp and a 621 are two of the most enjoyable saws I know of to run. Not high power either one but smooth and pretty quiet...decent AV...plenty of grunt if you just let them do their job and don't over try to load them. When cutting to their max you always have the feeling that you have a quality made tool in your hands....

Here's an old war horse........someone has already bid $0.99......

I could pick that exact saw up locally for $600, if I recall the price correctly.

Well....in the world of 111's that's pretty reasonable these days .....with a B&C especially.....
