Bought a new 201 and was disappointed to find out that it was not a M-Tronic saw. The Stihl website has a saw comparison chart that shows the 201 is M-Tronic. Turns out that the M-Tronic version of the saw is not yet available. Had trouble with the saw on the second tank of fuel which is when I discovered that I hadn't bought what I thought. Yeh, I'm stupid. Had several email exchanges with Stihl tech rep who informed me that saws of serial number 177543232 and above, already have the carb and timing mods installed. The saw worked well for the first tank of fuel. When cutting in the horizontal direction, the saw ran out of fuel. After filling the tank, I could not get the saw restarted. Finally I got it started on partial throttle but it would not idle. Long story short, I think that the fuel pickup was not at the bottom of the tank and maybe there was air in the fuel line. It took many tries of getting the saw to run and then running very roughly until the thing finally ran well again. I had to tuck the fuel pickup down into the bottom of the tank. Since then, the saw has been running well. I'm pretty happy with this saw. One odd thing that I also learned from the tech rep was that the owners manual settings for the carb are wrong for my saw. It states that the low speed screw is set to open 1 turn. My doesn't even have that much adjustment. It's 1/4 turn open.
