That 200T is was having trouble with is gone. I sold it and bought a Jonsered 2139. The Johnny seems well built. It doesnt have the chain speed of the 200T but has torque to spare. Its no joke in 8" wood. I only have a few tanks through it so Im eager to see how it runs once broken in. It starts like nothing. One pull with the choke on, next pull its running.

I still need to find a Jred source near me. I really want one or two for back up saws. Unless I like them too much

Talk nice to RBtree and maybe he will show you his muffler mod tricks, he seems to be able to make them walk the walk!

THE CALM ONE!!!!
You mean the 200t that was a pos? Or all 200t's?
Lol.
I hope it works well for ya!

Sounds like a carb replacement for me.

I'll put my little project from today up here in ya thread.... Since it is sort of related 
Since I have had no time until the last couple days... I had taken my newer 200T into the shop for analysis.... It had been bogging down and leaning out and would not stay in adjustment.....
Tech told me it was blowing fuel back up the carb instead of sucking into the intake. His analysis was that the piston skirt must have worn a tad on some dirt or something (as the saw has not a lot of hours on it) and it is something he has seen before. Soooooo I had a brand new Meteor piston set in the shop, a couple of NWP Ductile Split ring sets I keep about (as they are the same for my FS250 s, 40mm). I got OEM clips and bearings. Opened the saw up, the piston does look worn funny. I did find a couple of pieces of dirt covered with oil down in the case. Cylinder looked peachy.... Cleaned it up and slapped it back together. Brian the muffler looked fine, just a little carbon as did the arrestor. There were signs of something ingested and now stuck on the plate that makes up the arrestor. Not a normal carbon build up. I have like 4 filters for this thing so I always have a fresh one... Best I can figure is I got something in the carb changing the filter out one day and did not notice. Pretty careful about that. Took her outside and fired her up after readjusting the carb.. Seems great and I will get her dialed in tomorrow when I have some day light. Here are some pictures of the piston and cyl. My macro does not always work real well or consistently. Especially in between chasing a 3 year old that has a handful of parts
Also found some real fine stuff partially clogging the tank vent as well. Probably the same stuff down in the case.

All. The POS I bought had all the performance any of my others had, it just wasnt reliable at all. Most of my 200Ts over the years were pretty reliable. Some acted up, but nothing I would get too mad at a saw for considering how they get used.

I have no idea what that black stuff is that finds it's way into some of the 200T crankcases but that one looks clean as a whistle .It might be the deteriating material used to hold the crank bearing rollers in place for all I know .
As far as a 200 or any saw not runing right there has to be reason which is some times rather hard to determine I must admit .

Some times I find black stuff in the cases, usually it is bad oil that was not up for the temp.
Oil that get too hot too fast and gets sort of sticky almost solid form. Some times as pellets, some times a glas like brown surface.

This was clearly a couple chunks of crud. Not carbon. Not dirty oil. The rest of the case was spotless. There was also some that appeared at the spark arrestor... Almost a glass like carbon.. couple of blots of it. The stuff in the case looked like dirt, fine sawdust and oil. 
I dialed her in last night as I was too anxious to wait until morning..
Turning 14000 in the sweet spot with no arrestor.
Magnus or Al? This is the first time I have tried the split rings in a 2 stroke.... What has been your experience with them? Any advantages/disadvantages?

What it the world is a split ring? I've seen overlap iron rings on old hit and miss engines but never on a modern engine .

Absolutely. The 200T I started this thread over was a constant battle. The flywheel spun outta whack one time, the coil was failing another time due to getting rain on it, then it starts this BS that I started the topic over. Too many times since spring that this saw left me in a jam in a tree. Truth be told, I could have had this last issue fixed, and never had trouble again for years. OR, it could have been the next failure shortly after. I get to a point where I quit wasting time driving back and forth to the dealer. Next saw.
Ive concluded in my short life that when a company makes 10 of one item, all in a row off the assembly line, 2 are going to be super performers that seldom fail. 6 are going to be good all around items that live up to their expectation and fail now and again. And 2 are going to be shit that are one problem after another. I have had several 372's over the years. I have one right now that right out of the box blows away any 372 I ever touched in my life. It has NEVER acted up once in 3 straight years of daily demanding use, and has been rolled on twice by tree trunks and suffered major injuries each time. I believe that in that batch of 10 saws on the assembly line that day, I got of one the 2 super performers.

Split rings?
Were edges are "floating" Like this: // no pin?
I would not put that in a saw, too high risk of movement and snagging on ports edges. Pin need to be there to make sur the ends are in correct place.
14000? Really?
And then drops to 9000 in work rpm... Seems a bit of waste... Turn it down a tad and it will hold rpm better and not get so hot.
Ignore the rpm and set it after performance!

Ha no they don't drop to 9000 .
Say just came in from carrying in the firewood and testing the pair of 200T's .Both did fine on 16" ash hard as a rock which if anything would put the little rascals under a load that certainly should have .
I think the super bee might still have a slight air leak because I had to fatten it up more that it's over 15000 rpms free air sounding like a model airplane engine on steroids .I only had a used seal though which was iffy at best but it doesn't appear the carb was the problem .
So on that one I think a new set of bearings and seals are in order .Prior to my half fast fix I couldn't get over two cuts with it before it leaned out to almost nothing and no I didn't continue to run it that way either .

I was ignoring the RPM... I tuned by ear and then used the Tach.... I will bury it in some wood over the week end to see if I need to richen it up a tad or not. Probably will tone it down just a tad.. but not much if at all.
I'll see if I can get a close up of the rings... They are split grooved. Thus the ring has a split all the way around the center. Pins on piston are there.
Made by NWP... Might wear faster with the smaller surfaces involved. The groove usually (by theory) helps lubrication.

What,the ring is built like a one piece 4 cycle oil ring then ? It would slosh a bit of oil laden fuel with it I suppose .
CurSedVoyce
California Hillbilly
Correct. In my mind anyway... Only 40mm made for a 2 stroke..

I've seen a similar type used on tractors .Actually on a John Deere A which carried three compression rings and two oil rings or could have been 4 comp rings ,I forget .That type was I think was the third comp ring .

Very similar to what I've seen before .A whole lot smaller though than a tractor ring though I must say .That old John was a 5 1/2" bore .

Curious to see how it breaks in. I gotta get in a tree real soon... I want my 200T back. Been working with the Echo 360T 
It does the job.... but ....... Lets just say I have been calling for a rear handle pretty quick with some displacement once the brush if off the tree

Is those Ductile Split Groove Piston Rings? http://www.baileysonline.com/itemdetail.asp?item=PRSD+4415&catID=
Good Bad?

If a 200T is running correctly it's got enough grunt to pull a 14" buried .I proved that a couple hours ago . It isn't like you can hook the dog and lean on it hard but it will get the job done if you drop the reins and let it run where it wants to .
