Check out Mike Acres site, you should be able to get the info that you are looking for, or someone here will have the specs. The 49SP is a good saw I have one that I use for cutting firewood around the house. It's built like a tank but it's tough and keeps on going.

Good saw. 49cc made in the late 70's and early 80's. They are descended from the Jonsered 50, 51, and 52 saws in some manner. Not exactly sure how though, but some parts are interchangeable between the models.

Yep, i think they cross polinate with Pioneer/Partners of the 500/5000 era too?

49sp
:agree2: the 49 sp is a real sweet little saw (My opinion) as plantbio stated they are of the same family as the 50,51 and 52 all 49cc saws. They are light duty open port, single ring 49cc. The 52 is set up like the 621 (closed port double ring and the same ignition ie. more heavy duty) I bought my first 49sp new in fall of 1977 and it finally died in its sleep many years later. Parts like pistons are hard to find. A number of people on here have used pistons from a 52 with good luck however I weighed them and found a little over 11 grams different (52 heavier) seems like that's alot balance wise. Anyway the Acres site will give you all the specs. However he does not state points settings or timing specs more or less inferring they were electronic ignition. I have 5 49s and they are all points ignitions. Good quiet solid saws.

They were a little before that era. They were true Jonsereds. I think they would cut just as fast, despite being a few years older.

My dad bought his used in the the late 70's, and used it as his primary saw until he got his 70E. They are good little saws for sure. I love it.

Back in the early 80s I had a partner in my sawmill business and he had a 70E. When we would cut saw logs in the winter he would fell with the 70 and as soon as they would they would hit the ground I'd start limbing with the 49 and he would start bucking the butts into sawlogs as we yarded with a 4wd Long. Spruce and pine mostly. We were a bit younger then and could hot yard a few MFT in a day (Spruce tops went into pulp and that slowed us down some but payed the overhead.) I've got a few hours in with both saws.
In their day they made the old SXLs and 10-10s look pretty slow, loud and caveman.

Today, they still keep up with saws of the same cc. In big wood, my 70E will cut just as well as my "higher tech" 2171.

Very cool; I've got 5 of them myself.
I love these saws, and use them right along with my newer ones. Considering it's a 30 year old design, I think they were way ahead of what else was out there at the time. And I also think they have aged well in the sense that they do not feel all that dated when compared to todays saws. Power wise, they are only slightly behind any of todays 50cc class leaders. They don't rev as high, (10,800 max), but you can lean on them a bit more than the newer stuff.
Like any old Jonny, parts are hard to find, so I always recommend grabbing any parts saw you can find, no matter how trashed it looks. There's always something you can use.

I agree spike60 the jonsereds that followed seem very tinny to me atleast. I love to hear that low quiet purr that those little guys make in the cut. And with a good sharp .325 they will hold their own. I've always had 16 in bars but I just picked up another 49 with an 18 and I like that real well. Not that I gonna use that saw to cut larger wood just not having to bend over as much when cutting on the ground. :agree2: Picking up any Jonsered parts saw no matter how trashed is NOT CAD just self-preservation!!!

Parts hard to find? A friend of mine has enough parts for these 49 SP's that he could build ten or more complete saws. Plus a slew of other vintage Jonnies.
