I've moded several 201Ts as I outlined in the first thread I did on them. It had been a while since I ran a stock one, and wanted to try the new baseline carb settings that are being put out by Stihl. I picked up another new 201T this morning. The H needle was already all the way rich against the stop, as they usually are. The L needle was out about 1 3/8, so I back it out another 1/4 turn to the recommended 1 5/8 turns. Surprisingly, throttle response wasn't that bad off idle. I expected it to be worse. However, the power is still extremely anemic. The saw has very little power and lugs very easily. You'll see the saw run stock in the video below.
So, off came the muffler, carb, and flywheel. The H limiter was drilled out, the ignition timing was advanced 6°, and the muffler was modded. Interestingly, the L needle ends up just past 1 turn out, leaner than stock. Usually, a muffler modded saw like more L than stock. Not in this case. The H has to be backed out about 1/2 turn, ending up just past 2 1/2 turns. There is still plenty of adjustment range at this point.
The change is night and day. You wouldn't believe it's the same saw. These are the kind of gains you expect from a very successful port job. What was a very anemic little saw, turns into the little screamer we've come to expect from Stihl top handle saws. I guarantee you, a 201T modded as above, will not disappoint. They are a very fine running little saw.
