Hello all... I've been away from the forums for a while (Darn work keeps getting in the way of my Stihl-Life).
Anyway, I picked up a 200t that ran okay, but would lean out and die after a minute or so of no throttle. So... I removed the carburetor, cleaned it, and adjusted the metering lever to flush with the Zama tool (it was a little low). I then reassembled the saw, and now it only runs when given full throttle, and the carburetor is spitting fuel out the back. I took it back apart, and checked everything, and even replaced the needle and metering lever from another c1q and still the same problem.
Now I'm confused, so I took the carb off a known good 200t, and it runs and idles perfectly.
What I need to know is, what could I have done to this carb to make it run so erratically and blow gas out the intake? I've done dozens of these, and I've never had this problem. The diaphragm isn't the greatest, but it ran okay before. I tried 2 other diaphragms that were in similar condition, with the same result. I'm just glad the carb is easily removed from this saw..
Any suggestions short of buying a new carb would be appreciated.
I should also mention that running the H and L screws all the way in does not stahll the saw, it keeps spitting fuel and at times will run rich and surge.
Thanks in advance!
