The 80 surely is a cool saw, but is there a point except for that?   ;D

Point to what?
I wonder about that myself - it surely is one of the cooler Jonsereds models, and was the forefather of many later 81 and 87cc Jonsereds!

For the enthusiast, it's a lot of fun to work the old saws now and then. Yes they are dated and lack a lot of features we want when doing serious work. But to cut some firewood, they are still a perfectly viable saw to run. I actually run 49SP's and 70E's quite frequently. They were somewhat ahead of their time, and consequently don't feel very dated at all.

That are the right words " nice written"

The Jonsereds 80 was my classic logging saw. First I owned and worked with the 621 in 1974, then a year later upgraded to the 80, I loved the power and toughness of that saw. The inboard clutch was unique for the time also.
 My older brother had a 111 Jonsereds, but his 80 was quicker cutting in the local powersaw speedcutting contest.
 Heres's some pictures from 1975 of myself and my 2 older brothers racing our 80s at our competition cutting 12"x12" white spruce. I'm in the fur cap at 17 years old. I was the green horn there as the picture shows me cutting a line which disqualified me, cut between the lines only was the rules.
My oldest brother Cliff [ in the vest ]was the champ for years, one trick he did to his 80 for extra speed was remove the bottom piston ring, but that was only part of his technique ha ha, he could file a chain better then anybody in the area plus super quick reflexes from the cold start, the first down cut, the 2nd up cut and the final down cut.

Removing the lower piston ring from saws that come with two isn't unusual at all, hardly a "Secret" (but it may have been back then?) ???

I still couldn't imagine trying to keep the 2nd up-cut and 3rd down-cut between the lines in timed cuts.  Looks to be about 2 inches between lines

Did they do this for cold dead start racing too? Then I couldn't imagine the 1st cut between the lines either.

Yes we did the cold start too. Those 80s had lots of compression and you had to roll them over just past TDC before hand in order to get a quick cold start.
Yes the lines are 2" apart and on a 12"X12" they seemed a lot narrower.
Took a lot of practice and skill to not hit a line. This marked cant method came from out east via a few Frenchmen from Quebec, that's how they did it out there since the early 1960s.
I remember seeing photos from the 1970-80s of marked cants in contests in Maine, Vermont, Conn. also.

Skill and speed is what it proves. But seeing its not poplar today is relative to not seeing many 8 hr a day pro end users around also.
