I've always heard that the 019T was a saw to stay away from, due to the difficulty of working on it. I had the misfortune of having one fall in my lap this afternoon. I take care of a couple tree guys saws and he brought this one to me to get running. Well, it's reputation is well earned. I ended up having to completely dismantle the saw just to get the carb off of it. It's a clamshell engine with the reed cage and carb bolted to the front of it. Fortunately a trip through the ultrasonic cleaner had the carb working good again and the little saw lives to run again. This little saw is unlike any Stihl I've ever had to work on. Most Stihl saws are very easy to work on, even back to the earlier models. This one is certainly an exception.
