Seems they have 2 carb styles for sale, both have 2 screws, on has a limiter on the H screw, probably so as to not get it too lean.

Yes Mike is the lead technician at my favorite saw shop. Sorry that I was less than clear on that in my post.

Excellent response time on your "beg".  Did you get both the IPL and the Service manual?  I like the IPL as the pictures of the parts in the blowups help with the service manual descriptions, at least for me.

Good luck on the reassembly.  Hopefully they did not "conveniently" leave any parts out when they gave you your saw back. (yes I am cynical)

It looks like the one has all three adjustments and the other has a plug on the high speed mixture adjustment.  The plug does have the appearance that you might be able pull it and put a jet screw in but ...............................

Most of the Stihl carbs after mid 90's have a black cap that limits your range of adjustment.  If you are careful they pop off really nice and you can either leave them off or after you do what you need put them back on.  For "NORMAL" carb adjustment they are just fine they way they are and I leave them on.  I ended up with a piece of deteriorated fuel pickup body (filter) that got in the carb and was able to flush it through by opening the mixture up A LOT and then after it passed bringing it back to normal

Yes, I got both manuals

I got the saw back together with all the old parts... I did have what seems to be an extra hose in my bag of parts. It does not seem like it is off my saw, almost looks new.  Both the oil and gas hoses are intact, the impulse hose is there so I'm no sure what else it could be.

Thanks again for the help.

I use a drywall screw to remove those pesky limiters, my 046 stihl has (had) those little red ones. I too find the illustrated parts breakdowns very helpful and I hate to admit it but I read warnings as they are usually the most efficient way to fix problems. Frank C.

UPDATE::

Still looking for a carb replacement, 37 varieties of knock off carbs, none with a very good rating. So I was trying to fine a Walbro replacement :o :o  Mine is stamped WT-403B, I have found NONE at any price with that number!!
The ones I am finding listed for a MS260 are a WT-194 (a little different configuration without the little snorkel thing on top, although "they" say you can switch the top plate out and put that snorkel on it, but will that alter the way it works?? or can I use it as is and use the air filter made for that style? )  And I've also found a WT-426-1, also says it is for the MS260, and has the snorkel , looks the same but still wrong number.
Are these different or just for different years, I can also find no cross-reference for these things. Apparently mine is an "intellicarb" or something, but I find little reference to it.

UPDATE TO THIS UPDATE  ;D

After all morning doing research, and reading a lot of posts over on the arborist site I ordered a carb. I ended up ordering the WT-426, which apparently the same as the WT-194 but an earlier model AND has the little snorkel on it so it more closely matches mine, and was designed for the snorkel. (apparently the snorkel is part of the intellicarb set up
Should be here in 4 days so stay tuned!
Also (going back a few posts) going through the bag of parts that came with my disassembled saw was a new fuel line and a new fuel filter, apparently they were going to start work on my saw when I told them no and left them in there..so I got a couple freebies.. that's my story and I'm sticking to it!!

Never really understood what the precise issue was with the saw. 
Did it not start at all?
Did it start and not run well?
Did it start run and die when it idled back down?

Since you are going down the road of replacement instead of rebuild (you said you had not even bothered to try to start as you did not want to put fuel on it)  I was wondering if you had considered soaking the carb in carb cleaner (you know those gallon buckets with dip trays)  and then blowing out with compressed air to see if that might have an effect.  Since you have the new pickup body (fuel filter) and new fuel line, install those now and when the new carb come in you will be ready and waiting and you might try the old carb after a good soak to see what happens.  Of course those soaks can be hard on the seals and you might get a carb air leak.

I have had off and on problems with the way it ran (for years).. Sometimes it seemed like it ran fine, other times I could not even get it started, and if I did get it started it might run ok for a while then quit. With my last fight with it, it would start right up and run good with no load, start a cut and it would die... then restarting it would be more difficult, but it would be the same.So I opted to (A) take it in, and then (B) to replace the carb mainly cause I was tired of fighting it.
It is a relatively lightly used pro grade saw, but it is also going on 20 years old. After all I've been reading, replacing the carb with the fully adjustable one, and these saws will really wake up. So I thought I would give it a try, especially since a new comparable one costs north of $500 these days.

Sounds like the high mixture port had an issue (and that was not adjustable on your original carb) and may have had an obstruction of some nature.  In addition the low end mixture may have had issues as well.  A full adjust carb is nice but unfortunately they have been moving away from those for years.  The problem that I described earlier that had pickup body debris would not have been able to be fixed easily if the high jet could not have been adjusted full rich to allow the debris to pass. 

Glad you found a replacement that is full adjustable.

Chain saw seems to run fine, smoking a little so I'm thinking too rich. According to my book the initial settings are as follows.

Turn high speed screw (H)
counterclockwise as far as stop (no more than 3/4 turn)

:
Carefully screw the low speed
screw (L) down onto its seat
(clockwise), then turn it back one full
turn counterclockwise.

Not really understanding the instructions on that H screw. Any advice on where to set this, I know its not good if I get too lean with it.

ALSO... on the "snorkel" on my carb, neither the old one or the new one has a O-ring on it. I've seen pics with an 0-ring being on there which makes sense or you could get debris entering that air filter at that point and entering the carb... yes or no on the O-ring? I put one on there (2 actually to get it to fit as I did not have the correct one in my kit. ) Leave it on or take it off?

First off congratulations.
Cheaper than a new saw and cheaper than their rather high total repair estimate price and even cheaper than their carb by itself.

As to the O-ring question

From my service manual 026/024 which is not the same as your model but................

" On machines with compensator,
inspect 0-ring on stub and install
a new one if necessary."

Thus I would have an O-ring on it personally

Here are the 026/024 service manual tuning instructions.  Again a different model but all the Stihl carbs that have H, L, LA tune the same it is just the max RPM that varies.

I did read your 260 tuning instructions from a users manual and the assumptions are that the tuning caps are on which prevent you from turning more than 3/4 turn.  With your new carb you don't likely have the caps that stop you at 3/4 turn.  Be careful unless you have a good ear or a tach.  The term two- stroking is used to help ID max RPM and back off just a hair from there.

From the manual
Standard setting
To readjust the carburetor, start
with the standard setting.
- Carefully screw down both
adjusting screws until they
are against their seats.
Then make the following
adjustments:
H = High speed screw (1),
open 1 full turn
L = Low speed screw (2),
open 1 full turn
A slight correction to this setting
may be necessary at high altitudes
(mountains) or near sea level.
For corrections to high speed
screw (H):
Use a tachometer - do not
exceed max. permissible
engine speed.
Engine can be damaged by lack
of lubricant and overheating.
Maximum engine speed with bar
and properly tensioned chain:
13,000 rpm (024)
14,000 rpm (026)
Note: If no tachometer is available,
do not turn the high speed
or low speed screws beyond
the standard setting to make the
mixture leaner.

Furthermore, the engine speed of
machines with catalytic converter
must not be less than 12,000 or
13,000 rpm.
- Check chain tension.
- Check air filter and clean
if necessary.
- Inspect the spark arresting
screen and clean or replace if necessary.
- Start the engine and warm
it up
- Adjust idle speed correctly
(chain must not rotate).
Turn high speed screw (H) and
low speed screw (L) clockwise for
leaner mixture at high altitudes or
counterclockwise for richer mixture
at sea level.
Turn screws very slowly and
carefully - even slight movements
produce a noticeable change in
engine running behavior.
Note the following when making
corrections to high speed screw:
The setting of the high speed
screw (H) affects the maximum
off-load engine speed.
If the setting is too lean, the
maximum permissible engine
speed will be exceeded and
increase the risk of engine
damage.
Adjusting engine idle speed:
A correction at the low speed
screw (L) usually necessitates a
change in the setting of the idle
speed screw (LA) (3).
Engine stops while idling:
Check standard setting.
Turn idle speed screw (LA) clockwise
until the chain begins to run -
then turn it back one quarter turn.
Chain runs while engine is idling:
Check standard setting.
Turn the idle speed screw (LA)
counterclockwise until the chain
stops running - and then turn it
about another quarter turn in the
same direction.
Erratic idling behavior,
poor acceleration
Idle setting too lean.
Turn the low speed screw (L)
counterclockwise until the engine
runs and accelerates smoothly.

I did find on that IPL(?) manual that they showed the O-ring so I left it on. Even on the shop manual I got, it showed dealing with the limiter, and not giving me instructions like you did above , Thank you, So from what I read as long as I don't adjust the high jet less that 3/4 open I should be ok. Where I'm at I'm at about 560 feet above sea level.

And thanks for your help with this, yes instead of $240 to fix (ridiculous) or about double that on a new saw I kept everything under a hundred bucks!

Basically I would say yes. However it never hurts to be exact.    Glad it turned out so well for you.

Not that much money for this one

This is the one I bought about 10 years ago.  A bit more pricey now but it is a nice unit and worth it.  Can be used on things other than chainsaws.  Has lots of uses for any small engine tuning. But for 2- stroke Stihl equipment ( I have a few items) it is great.

As a technique.

I keep a small 3 inch soft bristle paint brush with me and lightly brush the air filter of debris everytime I fill the fuel tank.  Keeps air-fuel mixture consistent by keeping air through the filter constant.  With the flocked filters just be careful with them.

 (Yes I am a believer in preventive equipment care)

Re: Starting a search, Ideas... UPDATE!!

So an UPDATE to all this:

Finally got to actually put this saw through its paces yesterday, cut down and logged up a couple decent pine trees for the mill and did a bunch of clearing around my pond.. an all day affair. The saw ran great, all day long. Started up easy in the morning and then every time I stopped and restarted it was usually one pull and it was up and running again! I replaced the bad bar (and chain) with a Countrytime bar and chain from TSC and it seemed to do rather well also!
So plenty of power and easy starting and it ran great for the entire day, that has not happened in many years!

I am so GLAD to have my MS 260 back up and running correctly!!

Thanks for all the help, and I learned a bunch about how to tune my chainsaws to boot!

I am still very skeptic whenever someone tells me the fuel killed something. It would be different if it was a 1960's saw but being much more modern Fuel should never come into the equation unless you ran truly bad fuel through it not just ethanol fuel but contaminated fuel.

Carbs do wear out and need replacement and cleaning occasionally. It does not matter what kind of fuel you run. Fuel is corrosive. If the tight tolerances inside the carb get eaten away enough no amount of tuning will ever be able to fix it.

Glad your back up and running. One day I may actually get into tuning saws but I sure do love my M-tronic!!!
