Ms200t rebuild

[Al Smith]

Just some point of clarification,not that it means anything .If you are say bucking firewood logs,a lot of them you might run a saw an entire tank full of fuel before you shut it down, .Generally speaking that would be between 30 and 40 minutes depending on the saw and how much over stock it was .
If however you had a saw in a tree it would never see a continued long run like that .It might be in use for 6-8,rarely 10 hours but it would not be running all that time .I'd hate to guess how though in the course of a work day how many times a 200T goes from idle to wide open throttle or how many times it goes from dead start to run .These are not normal chainsaws by design .This is a sprinter,fast quick cuts .Not that it won't hang for the long haul because it will but that wasn't what it was designed for .
Now because it is a thoroughbred you have to stay on top of things if you want it to last .If that takes a set of bearings and seals or just seals don't dilly dally with it ,get-er-done .

If you are using a 200T in a tree you can burn a tank of gas in 15 to 20 minutes.

I have one that will in twenty minutes and one that goes for about a half hour .You put some soup to one they really enjoy gasoline .

Screen in maybe 20. No screen big hole 14-15 minutes knotty pine tear-downs . Me 20-30 screens in now I'm old. An hour with rigging and constant shutdowns. 3/8 LP always sharp. Chisel for quick cuts. My only mod. Remove every other muffler finger. Pull the screen and re tune for big oaks and dead hardwoods. You actually slow the saw down and let it breath for big hard stuff.

If you have one with enough oomph try a seven tooth sprocket and chisel .

Slow as hell climber 2 - 3 hours!

Following this thread with interest. Just fully stripped down and cleaned my 200t. Ordered new oem seals and unfortunately AM bearings. Decided to leave the oem bearings in as the side slop was 0.2mm. Which to me felt horrendous but when measuring seemed acceptable. Anyway from a freshly painted case to fully assembled took 2 hours. Not bad for a first tear down of one of these. Problem is the case now makes the rest of the saw look like an old bone.. they are the most fiddly little buggers ever. Especially the impulse hose to carb housing reassembly...

They are an interesting breed....
I have only worked on a few....
Seals, intake boots, top end rebuild... The top end one gut a squish cut and went gasket less... It was mean and liked the fuel...

So you said side slop as in side play?You have no up and down play? Are you sure the seals aren't giving you that impression?Push harder up and down and see what you got?

I did two hours today. Half tank ha. I was throwing thirty foot black walnut tops at them right up against a fence and pool. Spent most of it just sweating. Much better than yesterday. An hour of chucknduck. It was horrible!

Why? Do you climb much? A 200 with muffler mod and a sharp chain is dangerous enough when they pop. No need for that kind of chain speed up there.

Walnut sawdust burns skin when it sticks to sweat. And dont get it in your eyes!

Really naa. I could see a *f-wordin thing today when the drips came out of my shades on the last top pop. Rub it in.

Stihl never publicaly addressed the problem of the seals let alone the carbs

They just looked the other way while smart dealers and mechanics replaced the original (and brittle) 12x20x5 fiber seals (9640-003-1191) with the normal (and notorious) flexible 12x20x5 seals (9640-003-1190) used on the 026 flywheel side among others.
(Notorious for how big of a hassle it can be to pull one of the little rascals!)

As for the main carb issue, the C1Q fix of simply bypassing/blocking the pump circuit has proven to be effective over time and is fast and easy to do. The pump repair kit works for awhile if the piston hasn't galled the surfaces to the point that the 'O' ring just leaks again anyway due to the surface irregularities.

Stihl used at least a dozen different carbs on the 020T/200T and never did get it right over the long haul. Then they strato'd the whole deal with the 201T abomination which I see for sale in my area all the time in the $300 range when old 200T's still go for $500 plus. There's a reason for that.

One bad ass little saw that refuses to die in spite of Stihl and the everyday tree guys that abuse the snot out of the poor things.

oem bearings, seals and other bits ordered today.

last 200 i fixed got an AM carb from ddave ... huay(?) i think... worked very well
can't remember carb condition on this one...
Wish i knew more about these, but I'll soon get up to speed.

Actually very seldom since you asked .On the other hand people are always asking how to get faster cuts,this is one option .I mean think about it,do people ever ask how to make one cut slower?

Tell them to work on there chain sharpening skills or find a guy who can. Most climbers I see need more skills less mouth and some detox 50% of the time. I don't claim to know much just being sober and thinking be safe, tread lightly, has served me well.

Kinda like Randy said.
"Go tap at it just for the sound." That might get you killed in a tree cause your going to be, fast. Some decent rigging skills would help to.
Turtles live longer than rabbits.
Most climbers don't need faster they need more skill. Not always though.

You're missing the point .At one time we raced little saws over the blocks .The 020T and 200T were of course the fasted 2 cubers .I as well as about anybody else knows you don't have to soup up either one of them .
On the other hand we do because we can .--and we like to
You know at one time all you could get was semi chisel chain in 3/8" low profile ,now you have the option of true chisel chain,why because it's faster .In case you ask I know how to rig,disassemble a trees a tree,I can hit a stake driven in the ground falling a tree .I don't do it for a living for the simple fact of one, I'm damn near 70 years old and two there isn't nearly enough money in it for me .
Now by bud who owns the tree service I help out with out his equipment knows what he is doing,he's not an amateur by any means .I just happen to know a lot more about the mechanical end of things better than he .
In spite of that he does okay on most things .

Nobody ran a 200? ;-)
Okay Al I see your point. I saw your point the first time. I have run that chain on my saw and ripped some drivers off when a white oak limb chaired. Fun stuff with a square chisel chain. I don't recommend it or encourage climbers to do it. I ran skip on it in dead walnut. Don't touch the tip, just don't.

If I make 70 I damn sure won't be doing tree work. Firewood, maybe. I'll fell and tune up the bow. Hopefully some young bucks will buck up, pick up the chunks and leave the chain sharpening for me.

OEM bearings installed very little side to side compared to what it was..... Gaskets, seals and a new meteor all going in...

Sooner or later....
Sitting in the dark, big ass oak down next to house over all the lines....
Luckily I have a saw or two.....
