i bought a johnsereds 621 at a garage sale. i know nothing about it other than it weighs a ton and runs like a top. any one know its displacement or approx. age and so on. my searches have produced nothing
 
its a bit of an anchor. but the price was right. any clue to approx. how old it could be? thanks for the info
 
There are a few of us here that like Jonsered chain saws. I own a 621, and while I acknowledge it is heavier than some more modern saws, it seems to be a willing worker.

56cc with an 8-tooth sprocket, running 3/8 full chisel on a 20" bar...a guy would think the saw would be pretty wimpy, but it really isn't. Seems to pull hard at a little lower rpm than some other Jonsered saws of the same general era...there's a big diff between this saw and the 535, for example, that isn't fully explained by the measly 7 cc's diff.

621 is a quite good firewood saw, able to handle about anything around. The downside of the 621 is that it has been discontinued for long enough now that a few service parts are getting tough to find. I'd not let that stop you unless the saw is in almost perfect shape...to nice to use. With reasonable care it should last a casual user forever.
 
its in great shape and appears to need nothing. ill have to give her a try. thanks for the link rocky. i still must say its a load to carry around though
 
I had a 525 Jonsered I was glad I cooked it because the SOB never did run right since I got it. It was a light saw perfect for brushing but the MS260 that replaced it is even nicer :blob2:

All I can say about buying a used saw from a garage sale is buyer beware you could be buying a dead horse. The first thing you do is pull the muffler off if you can and see if the piston is scored if so walk away.
 
i had it running at the sale, it needed a carb cleaning but the price was right. the only ones i always but no matter are stihls . as long as the price is right. spare parts are nice to have
 
Manual for 621

i bought a johnsereds 621 at a garage sale. i know nothing about it other than it weighs a ton and runs like a top. any one know its displacement or approx. age and so on. my searches have produced nothing

I have the Operator's manual and parts diagram for the 621 on ebay this week. Anything you want to know from the docs?
 
I love my 621. Yes, it is heavier than today's saws, but she has lots of grunt. I run an 8 tooth 3/8 20" bar and never slow down in the oak I cut. These saws are bullet proof if properly maintained. Parts are a little hard to come by, but there are some good sources. Decent anti-vibe for a saw from the 70's, too.
 
I've got a 70E that is it's bigger brother. The saws were made in the late 70's early 80's.

Heavy but tuff. My 70E is 69 cc's and it has more grunt than you would espect from a sub 70 cc saw.

You are right on!

It is a really cool firewood saw for "yard" use, but a bit heavy to carry into the woods. The chain speed is quite good with the 8-pin (that was standard), no reason to try a 7-pin with reasonable bar lenghts.

Hmmm - something familiar with that post.....:greenchainsaw:

Specs out as so:

56cc/3.4 c.u. in.
45mm bore
35mm stroke

hope this helps.

The nearly identical 62 came out in 1968 and the slightly refined 621 in 1970.
The design was well ahead of its time, and production lasted until at least 1982, when it was replaced by the 630, I think.

Power rating was 3.6hp/2.65kW at 7700rpm, but it "seems" to have more, the way it cuts.

Even the anti-vibe actually works.

My 621 buy

I used my neighbors saw this winter to cut up a limb that came down in a ice storm. The limb was about 12 inches and walnut. The old saw went through it like a hot knife through butter. I asked him what it was since all the markings were worn off. He said it was a Jonsered 621. I thought it was a hell of a cutter if a bit on the stout side. I found one on ebay and bought it for $26. It took a long time to get here and I emailed the guy, so he threw in another one as a parts saw to make amends. Saw started right up, but as he said in the ad, it had a hesitation when at full power. Took it to my saw guy and now it's great. Not bad for a $26 dollar investment. JR

Wow....you got a real good deal on that 621 Jonny,..... $26 bucks..... thats almost free....the only downfall of that saw was the air filter, it would suck a lot of sawdust down in the carb.
Way back in '75 I used to run a 621 all day felling, and limbing for a tree length logging operation, when the 70E came out & I bought one I remember thinking how much more powerful it was over the 621, but the 621 was prolly wore out by then. Also the 70E also had a much better air filter on it & like Bama said they had real good anti-vibe for those days.....
 
Nice buy!!

I saw one today on craigslist for $150. I have borrowed my brother's 621 several times. I concurr with all the other assessments. It's heavy and it cuts well.
 
Garage Sale 621

I also just bought a Jonsered 621 at a garage sale. Does anyone have a bucking spike that they would be willing to sell for this saw? Thanks.

I find no reason for one, the weight of the saw and an 8-pin 3/8" rim (was standard) sure helps.....
 
Sawtroll--I'm going to get a new chain today without all the anti-kickback bars on it and give it a try without the spike. Thanks for the info.
