I would Brendon, if it is deemed a safety issue they sometimes can replace them under a recall/upgrade warranty. Some 046's had a idle problem going from horizontal to vertical and that is how it was handled. If you came in complaining they updated the carb no mater what the age of the saw.
The Stato charged 441 is the only one I have need to tune this way. All my others are more by ear on the low and mid range rpm, then I use a tach for checking/setting the max rpm.
Sawcollector had a thread about tuning the 441. I can't find it but it is not a simple turn the screws thing. Setting the low was a little trickier.
Thinking the 201 is similar.
So I agree with Skwerl, richen the low speed to slow it down.
Stihl tech here said most need some major adjusting of the carb after a few tanks. Then they run pretty close to a 200.
Don't own one so just what I was told.
But makes sense the 441 is a little different to get set right also.
Lean is what blows saws up, air leaks, carbs not adjusted properly, no oil in the mix. Those things all allow scoring and heat to build up, also may allow it to go over the max rpm rating for the saw.
I wonder if you can go up a tooth on the drive spur. For me that is what works with the 441, lets the motor drop some some in rpm but still maintain a fast chain speed.
