Aha I used to have all of what you described but now it seems they fixed the problem.
Should not be anything of that type in there. Did you pull the inlet valve and check for junk stuck in there?

Its a real pain in the butt to get started but when it does start it will stay running as long as I keep the throttle open.
When I started it today, it zipped up to full speed for a minute then it died.
Then back to laboring sound as it pulsated.
I held a branch up to the chain and it was able to cut it. So there is power. Not full power.
I have a C1Q-S61 Carburetor.
I did remove the Inlet needle 4116 121 5100 and the control lever to inspect, the needle looked new, and the hole below it had nothing stuck inside, I used carb cleaner and put it all back together.
Before I try to help the inlet needle (welch plug ?) seal by putting fingernail polish on the end, how do I inspect the impulse line ? I can't find the part number or the location of it on the schematic.

I disagree it will severely effect acceleration to WOT, and sometimes won't even get to WOT.

The needle is not a welch plug - don't put anything on that. A welch plug is a small disc of metal that seals off an internal area of the carb when pressed in.
Did you check the impulse line yet???

the impulse line is connected and looks good, under the left side of the air filter
Then the carb is bad can you borrow one to try?

I don't have a carb to replace it with, I will go buy one if that will solve this issue. If I have a C1Q-S61 Carb, what should I replace it with ? And where can I buy it ?

Run it in the house like everybody else.
Before you buy one if you are able vac test the saw. Stihl carb 11291200653 is the newest replacement without the stupid acelerator pump. Stihl dealer can order it or may have one they are 90.00 dollars or so. Can you post a picture of the airbox are where the carb mounts?

Just buy a NEW freaking carb..
I hate worse than about anything...too much time and expensive to fix carb problems
(especially the small carbs..! - the 200T has to be in a league of it's own..soo many carb models)
Let the 'hate' replies start falling...it's JMHO..!!
Even me buying and installing a carb kit...for $$ ...I always suggest just buy a NEW carb....

have you put a new carb kit in this thing yet?
does it floud out or go lean at idle?
have you opened the hi speed screw say 1/4 turn to see if that helps?
did you presure check the carb? should hold 10 psi or more
when was the last time the saw ran right?
need to get thing narrowed down a bit
put a carb kit in it first

No new carb kit.
It will not idle, the only way to start it is to put it into cold start until it turns over once then warm start. After that it will run until I take my finger off the throttle. When it dies it does so like there is no fuel.
I have adjusted the carb to try and work out the issue. I just get the same result at different rpm. Still acts like it is laboring and the tip of the bar will jump constantly, like I am goosing it.
I do not have the tools to pressure check the carb. The seals on the carb look new there are no cracks.
The previous time the chainsaw ran, I just fueled it up started it, warmed it up and shut it off. I was about to climb a tree, I started the saw to clear brush around the base of the tree, started perfectly (1 pull). Then when I pulled the throttle it died, it would not start. I took it back to the rig and pulled the spark plug, it was very wet. I dried it off. After about 2 or 3 min of trying to start it, it turned over running as I described.

i'm starting to think it might be the coil, maybe
did you check the welch plug?

I have checked the fuel filter in the tank, the fuel lines, new spark plug yesterday, the inlet needle looks new and is installed correctly, the welch plug is not loose, the impulse line is connected and in good condition. I have used carb cleaner on all ports on the carb, all the ports allowed flow.
I bought new gas and mix.
The chain is almost new, the bar is well used but the rollers are fine and move well with just my fingers, the chain brake is not on ..., the chain is not too tight, the air filter is clean.
This saw is about 5 or 6 years old, it is cleaned just about every time it is used. This is the first problem I have had with it.

It sounds like your saying the revs are jumping up and down quickly. You said like your goosing it? If so, doesn't really sound like a carb issue, usually most carb issues on 200T's, they fall flat on their face when you try to accelerate throttle.
