Title: Jonsered 2083
Post by: Cut4fun . on March 30, 2011, 06:31:05 pm
I missed a jonsered 2083 and 2077 today on ebay. I bid what I felt they were worth dead needing top ends at least as listed.

My question is, I know the 2083 came in 77cc and 82cc. Is there any labels, decals or markings so we know which ones are 82cc and 77cc. 

I heard and read in the past that there was 2083 and 2083 II. Do they say that anywhere on the saw?

On the starter cover, at least.

The 2083 was 82.4cc, the 2083 II was 76.5cc, and a later EPA version for the US only, as far as I know.

DY how do you think it compares to other saws in the 75cc 82cc class? My stock 505 82cc didnt impress me as much as the 80cc echo.

Then again I havent went through the 505 yet and thinking it is in need of a carb kit. 14K is what I found the 415 and 505 like stock.

I would have to agree with you Kevin. Now mind you I ported it a little, but the way it runs reminds me or a 7900 stock (I have never run a ported one) its very smooth lots of torque but it doesn't have that zing.  I feel confident a 460 would beat it. There is still a lot to get out of it as far as porting, I don't know if I want to push it or just move it down the road?

I guess I need a little more time with it, maybe an 8pin on there and compare it to a 372 and some other saws.  I haven't run saws very much lately.

I wonder who built Jerry Gingras Poulan 5 cube? Whoever it was did a great job and I would bet on a Marcel MVP build.

I can see why they can be built into a good 5 cube.

If an Echo beat it, I assume something is wrong with it. ;)

14K is more than the recommended max, but such things happen..... ;D

oh they definitely have potential.  I basically did a snelly to it.  pulled the gasket widened the ports.  the squish is still up around 28 thou and I am sure I could get a good bit more by tweaking a few things  it not even really muffler modded the baffle is still in.

ST the saws are normally limited to 12.5k  I think so it is a bogus max rpm.  so you think the echo shouldn't be stronger ST I guess Kevin will have to go to the wood pile with the video camera and show us. :D

The WS manual from 1996 say max. 13.5 k for the 2083 and the 2077.

Post by: Cut4fun . on April 27, 2011, 01:43:56 pm
From what MM says the rev-limited green coils are only good for 10k-11k anyways.  13.5K max is usually plus minus 500 rpm.  ;)

He also says his 475's were four stroking till 14.5k. Just like mine they 4 stroke till 14K

Do you have the rev-limited green coil in it?
well the coil is green! :'( finished putting it together. i couldn't stand it. i had to see how it runs. seems to run good. nice throttle response. idles ok too. ;D
If your coil is green it is rev limited. To about 10K at that.

here is my 475 You can hear it still 4 stroking a bit when it comes out of the cut and its set at 14,500.

My guess is 83cc because i think it would say 2083II on the starter if it were 77cc. But i'll know for sure when i pull the cylinder..

.10 right  about the same as the bb372 in the the 475. The  intake sure seems to make the 475 run. Who knows till we try it.

If you can get a 505 piston I would get that.

I was going to try a 066 in the 1st 505 I got. The skirts are loose on that one.  I have 2 505 and 1 good piston.   :(

If I am thinking right. I am thinking only .075 on the intake side.

385 piston is real tall also. You could add your own windows if needed. The 288 piston is shorter but wider skirts than a 066. I do remember that from when I was going to swap a piston into a 066.

It would, unless the starter cover is from another saw - you never know on used saws, before you check.

066 Meteor piston is .020 higher then 2083 OEM piston. Squish with gasket, OEM piston was .041. With 066 piston squish is at .021. Comp is at 170 pounds. The 2083 rod is wider than the 066, piston needs to be opened up. Runs good ;).

What did you use to widen the piston where the wrist pin fits to the rod?   I would like to know in case I ever decide to do this kind of mod.   Saw looks good and I bet it runs good.

baileys pizzed me off so bad on my last order after 3 days of trying to order NWP piston and other things.  My paypal was on hold by them but they said they wasnt showing my order etc etc etc. Plus wouldnt give my credit for my $10 off code. I had written that off already and just wanted my order processed.
So day 3 I said just cancel my freaking order and ordered another 066 afm piston.

Well as luck has it I'm opening this one up. Started on it yesterday.

Ron I paid closer attention to my measurements this time and measured the squish closer to where the piston and cylinder  intersect.   I came up with .0245 at tightest on the afm 066 piston with used gasket.

The oem 505 one on the other saw when I installed today was .040 with new oem gasket.  I checked the 425 top before puling it and it was .0435 with used gasket.

not in wood. rained all day. 

Did you check psi on yours?  LOL I see it now 170psi?

New caber 1 ring on oem, so both will be like new saws to test with. Green one has 2 rings that came with the afm piston. 

yellow v/s green one.   I could feel the difference pulling over too.

Will have the strongest 7900 local along  for comparisons.

Ron see if your thinking is like mine on this.

After clearing my mind last night and thinking about this from a racesaw build perspective. I would choose the 475 505 to build as a racesaw before the 7900 though.

Watcha you think.

I would think the quad transfers of the 7900 would be over the single transfers of the old school design 475 and 505.
I believe so stock - but understand there are limitations to how much you can do to a 7900 cylinder (lack of metal in critical areas), compared to some Husky cylinders. I don't have a clue how a 2083 cylinder is in that regard though...

Here is the small outer dawg I am trying to make myself put on one of my saws.  I just dont know.  I like the smaller spikes over the large west coast ones that come in the full wrap set up.  I am still just undecided.

They even look uneven like 1 would be in the wood before the other when felling. Is there some kind of reason for this?

Those are the same spikes I have on my 2083.   
I just checked them and if you look at them sideways with the saw they are the same length.

The only thing I noticed was the points on the inner and outer spikes are staggered a little bit making them look odd.

Thanks for info. The 2 pics I seen both were weird angles like that 2083 pic.  One was on a 505 too.

Well after searching high and low and only turning up 2 used ones that sold as much as this NOS outer dawg.  I had to break down and pay $25 shipped for this Jonsered 2083 outer small spike for my poulans.   :'( :'(   
Might just put it on the NOS metal 2083 clutch cover and run it on whatever saw needs it at the time.   8)



Poulan jonsered part number  503742801

Even checking with the jonsered dealer on this site he confirmed NLA.

Guy showed up with a 6'er of 3rd shift and 6'er of Edmond Fitzgerald beer and  enough cash for my labor doing his saw work to pay for the spike.  8)

Amazing how  things work out sometimes.   :P

I just mounted the outer dawg on my metal jonsered cover and put on my 445 for inspection. Perfect dead even alignment. Nothing like that pic I posted earlier that throwed me off looking at it.

I'll post some pics later when I get done with evening activities.

I dont know if I ever mentioned but found a air leak at base gasket area as to why the 505 in 1st page wasnt impressive to me then.  Ended up putting a nicer better 505 topend on that saw and new oem base gasket.

I bought this saw about 2 years ago and then have never got around to using it yet.   As you can see it is in very nice condition.    I plan on trying it out but other things just kept me busy but maybe this summer.
I do not believe I have ever shown it on here before so I took a couple of pics.

I have two 28" bars one I used on the 475 and the other for the 505's or 2083.   I would have to look at them again to get the drive count.  Really I should see if they are both the same.

Nice - and it looks like a real 82.4cc 2083, and not the 2083II (that really is a late production 76.5cc 2077)!

What is the serial number?

Thanks, 1997 week 46 is a really late true 2083, specially for the US - so you may need to check the bore of the cylinder to verify that the labels aren't lying.  ;)

That's pretty much right at the time where EPA became an issue, so it might be one of the very last 82.4cc ones.....

1997   2083 Turbo  83cc
1998   2083 Turbo  83cc

Thanks for the info Kevin.

I decided to check the bore anyways.   I used the solder method and checked it twice.  It is definitely 54MM.
I also noticed it has the green coil which I believe was the limiting coil.

Title: Re: J-Red 2083
Post by: Cut4fun . on February 27, 2015, 03:11:04 pm
Green coil on my 505 and 475 was limited like 10-11k.  But the green coil on the 445 isnt.   I left the 445 coil in being it was unlimted and into the  13's which is all I needed for stock saw.  The 475 and all 505's got unlimted partner 5000 or husky 55 coils.

That's really odd, considering that the max power rating was at 10,000rpm for the 82.4cc 2083..... ::)

Max recommended rpm was 13,500rpm, according to the 1996 WS manual (the file is too large to attach).

ST others have seen what I have.

copy pasted info below.

IPL's the Poulan Pro 475 and 505 used a different coil part # then  the 415, 425 and 445 leading me to believe that they did indeed have a rev limited coil on the 475 and 505.

Searching found that the part # for the 415 425 445 coil superceded to part # 544018401 which is a  coil on a bunch of Huskys like a 55  etc.

Green coil 475  only turns a little over 10K.

Been pulling parts from the shelves for a guy in BC for a 475 2077 build. Well the more we exchanged emails it turns out he has a 2083 already with bad crank and cylinder.

I told him I would pull my last 505 cylinder I have on my running wild thing 505. Also that the cylinder wasnt perfect as it had been scored twice in the past. Cleaned up for a runner for me but not the greatest.
So it looks like I will pull that cylinder and the good crank from the 475 with rednecked case.

Says he just likes this series of saws and wants to keep it going and cant find parts or saws in his area.

The red jonsered 83cc 2083 had lost a battle with a tree. I was just hoping for a good piston and cylinder. I might have a good crank and new updated oiler set up too.  8) 8) 8)

Every so often I get the strong urge to pick up or build one of these saws.  They're strong runners, good lookers (I especially like the Jonsered versions) and I like the way they handle.

Have bid on a few over the years.  Never really put a winning effort into it however.  I already mess with way too many different makes/models of saws as it is.  Taking on another saw series would be lunacy....

I know what you mean Aaron.    But it keeps it interesting.   Just like those Homelites I had been working on.  Definitely different from some of my Poulans.

Now that why I do a couple series and then I will sell out of them everything. I did that with the 166 084 066 365 362 372 500 5000 490 590 325 already.  Wiped the shelves clean of then then all the parts.

Then I will dig deep into my new series likes to explore and learn on.

Thats why you will see me selling off whole series of saws at times.

When I sold you that 505 Roger I was thinking of clearing out this series.  But then I couldnt find anything in the 65cc - 85cc to replace the series I want to get into.

I have been wanting to do the 2186 2188 385xp 390xp though.  :P

Well if you come across one of the worm gears for the oiler like on a 505 that has the wings I am still in the market for one.   

No clue if this one is good or not yet. But since they are hard to find.
Have you looked at using the 475 metal worm gear as back up means. Looking how they slide into seal on 475 they may need shortened some since that dont happen with the updated 505 seal bearing deal.  Then again dont know as never tried it. Have you looked into this?

No I have not but sooner or later a 505 will show up and I will get a good one.   It really is no hurry but just keeping a look out is all.

Took a chance when I bought a 83cc 2083 off a guy. Heck he didnt know if it was a 52mm or 54mm. But I seen one hint that told me 54mm.  ;)
It lost a battle with a tree big time. I was just hoping the cylinder and pistons was good. Figured base might have been broken from the hit.

Real happy with the parts I am getting out of it. If someone needs a fly side down the road this one might be good just with a piece missing to left of muffler area.  :P

For once the chance pays off. Most times I do this I end up with one with big end rod bearing out of the crank.   8)   (dont know why G amble is a forbidden word in the software LOL = gamble )  ::)

Going to take a chance on this jonsered 2083 that broke a ring. Posted about it in the PP505 thread.  They used a lil red barn aftermarket piston kit.

That is a good candidate for the 066 stihl piston conversion.     I would build another if all my other saws were not already good runners.

Just had a LOL moment.  Just sold that NOS metal jonsered metal clutch cover and my last plastic red one too. Also a recoil shell for jred. Hope it is in decent shape.

I just buy to build and then sell later. I have any saw I need at my disposal already too.

Posted in wrong thread PP505.

Reason for picking up the 2083 builder. Guy still wants my PP505 WT I did back in 13.   
I was thinking of getting a new 6410H and getting a 7910 topend kit to replace it.   But then I thought hmmm I have tons of parts for these.

So if it sells I have this.

82.448cc 54mm x 36mm 2083 in hand yesterday finally = ups lost it for a day.   :D

Some different redneck things seen on just quick glance. Never seen tie straps used to hold the broken upper left av together before. Is a common one to break but this was a new fix to see.  Appears that a tie strap is used for a intake clamp too.    Hope to get more time soon to tear into.

Cleaning up the 54mm cylinder that the Little red barn piston broke a ring in.  I took some pics of older oem, lrb, meteor 066, old oem, side by side and side views etc. 

The lrb piston I am going to check out and test. But not as them come from lrb. Using oem circlips and seemed to fit just right.  The oem wrist pin was a no go. So the much shorter and thicker lrb pin used. 54mm 1.5mm caber ring to be used.  Had to clean up some of the scratches on the front of piston =wag from where broken ring fragments went through maybe.

The cylinder you can see in the squish where something in past had got up in there before. 

Having to come in and look at a IPL to make sure some of the fasteners I am getting from the bins are right.  Cylinder bolts etc.

So much fun looking for missing fasteners in about 6 bins with this series of saws. So far had all the replacement parts I needed on hand.

Had it pop on choke then seen it was flooding.  Pulled carb. Someone had the fulcrum way high. Going to go ahead and put a new kit, even though one there looks ok. K10-WJ   D10-WJ

 Had it running after carb rebuild. Was getting ready to stick it in some wood with 28". Backfired and all she wrote. Being the complaint was broken ring by past owner. I went to pulling muffler. Yep broken ring. Last time I figured the guy had ran the crap ring that came with the afm lrb piston. This time it was a new caber ring. So to figure out if it is the cylinder ext port or the lrb piston.

Post by: Cut4fun . on June 24, 2018, 03:40:12 pm
Tore back down for look see. Comparing my 52mm 50mm cylinders to this 54mm. I think someone opened some and didnt get enough bevel. I had checked them before putting back together but guess it wasnt enough after comparing the cylinders. So time for some beveling.
Had another thought while down. Hmmmm Jred didnt make a version of the PP445 P710 which is my favorite of the series. Have 2 with bad cranks and 1 runner of those.   :P

Post by: Cut4fun on June 25, 2018, 12:02:33 pm
Ext & int isnt pretty but think I was able to save what had been done by someone in past which was hanging the ring on ext side breaking them.   Running and taking throttle good so far.

Hope to tune and put in some wood when I get back later today.

Post by: Cut4fun . on June 25, 2018, 07:12:45 pm
Well dog turd.  Same thing, broke another ring running for less then a min. Never even made a cut.  Looking how ring is in port. They just went too wide.   So 77cc or 71cc she will be.
Title: Re: Jonsered 2083
Post by: 3000 FPS on June 25, 2018, 11:50:32 pm
You can try and bevel the port even more.    That is one reason I like using a ball hone.   It takes any sharp edges off of the ports.

Title: Re: Jonsered 2083
Post by: Cut4fun . on June 26, 2018, 09:06:20 am
Dont think it is the bevel now after doing that yesterday.  Thinking someone went to wide and that has something to do with it. Then again I could be wrong.
Was going to try and get time to measure and or compare to a stock port on piston today. 

The way the ring sticks out the ext port after breaking seems weird and I am WAGing for ideas to why. I thought it was beveling was not enough by whoever did it. Fixed that part I thought, so WAGing to other things as to why. Ring breaks right in the middle and right in the center of the ext port area.

Ball hone was used on 1st clean up and then again after adding beveling 2nd time.

Funny listening to it while it is running for the tell tell sound of when the ring cracks.  Pretty wild sound from a saw.
Title: Re: Jonsered 2083
Post by: Cut4fun . on June 26, 2018, 02:11:42 pm
Compared the port shape and width to a stock 475 cylinder.  IMO rules at my to wide WAG. Has to be bevel catching it. Worked over the little more as I guess lower could be suspect and hit the top some more.  But IMO there is more now then the stock cylinder has.

Think I may have just used my last 2 54 1.5 rings so need to order some more. 
Title: Re: Jonsered 2083
Post by: Cut4fun . on June 26, 2018, 04:11:00 pm
Hindsight now. But should have read the 1st ring the saw came in broke with. Then the 1st one I broke.   I just looked at the 1st and 2nd caber I broke and could see where it was hitting right beside where it crracked both times. First one of mine was hitting top and bottom on ring. 2nd one was just the bottom.  So tried to fix the crap someone did to it.
I found a used good 54 to put in it from a past build of mine.  Right now running and cutting.

Anyone have a new 54 1.5 to measure the radial wall thickness of? I checked the new broke caber 2.24mm and used one I put in 2.16mm.  Just was checking to see how much wear was on the used one.

In a bit to see if that green coil is going to be rev limited like the 475 505 was or unlimited like the ones in 445.  Right now around 11K
Title: Re: Jonsered 2083
Post by: Cut4fun . on June 26, 2018, 07:48:10 pm
2nd testing with 28" buried. Took it up to 12K. So must not be a rev limited green coil.  Which is cool. But saw failed while cutting 2nd block.
Sounded crunchy this time around, unlike the broken ring deal.  Will try to tear down tomorrow for a peek.

Strike 3 for this 54mm p+c. Stick a fork in it.
Even got the pieces out of the muffler with baffle still in it.
Just glad it didnt bend the rod.
Was tracing what the shape of the ext was on it on a 066 piston to compare to a stock 475. Yes both off centered I just stuck them in to trace onto them.

Wow that is a big port and no oval at the edges to allow the ring to come back in gradually.     I guess that cylinder is toast.

Post by: Cut4fun . on June 28, 2018, 04:18:26 pm
Thats what I was seeing and they had made it to flat at top too. To undo that I would have had to raise it even more to try and reshape it back. Already it had lost torque in the cut IMO so tried without that.

I had a race 166 that was way more before and it did fine. But this cylinder was just a mess from get go when received.

Chit need to find the bigger pic


Aslo folks trying to run a 54mm top on the 36mm stroke in the 5ci race classes is over the size limit allowed. If you get checked it is a cheater saw.  Have to run the 52mm cylinders or ;)

Was cleaning up the 2077 cylinder and getting ready to put a NOS piston kit in.   

Doing a much closer inspection.   :o :P

Finally getting back into one of my own saws I had bought thats been a problem child since arrived.
Keep breaking rings 2 times, then finally 3rd time fubarred the whole topend. No matter what I tried cleaning up someones past porting.
Think I just found part of the problem looking it over much closer this time around.

Got another call out of the blue from a small engine shop in Iowa.  Guy working on 2083. Needed plastic worm winged gear and clutch springs.

Not given up anymore plastic worm gears to we get a source for 3d making them. Guy in the chainsaw repair group suppose to be making them for us to try and test out.

Clutch springs are just husky springs on the newer clutch and I informed him.

Also told him he might be able to use the metal worm gear on the later saws that had the plastic worm gear. Anyone did this?

I know the oilers are the same. Just wondering if room since different pto seal and bearing set up.

Guy was selling 2 nos 54mm topend kits. 250 shipped a piece. 1 with 1 ring and 1 with 2 rings.

I just had to pass at that kind of prices.   

Someone must need 1 bad because the 1 ring set is sold now.

Post by: 3000 FPS on February 08, 2019, 07:49:08 pm
By looking at those 2 pistons they seem to have the same height from the wrist pin to the top of the piston, but the single ring has taller windows in it because it does not have that second ring.     I love that conversion of using a 660 piston by the way.   If I ever aquire another one of these saws that requires a new piston that is the route I will go.
