While fairly true, on this particular model, I have been doing a dickered with version for the tree care professionals that I picked up on from our very own
@sawmikaze . They are only muffler modded, the timing advanced and the carburetor worked on, which lets the 201 run quite well, yes they are not quite as good as a fully ported version, however the benefits are I can turn one around the next day after receiving it and at a small fraction of the cost of porting one. Which seems to be an advantage for the tree pro's in both respect's.
To differentiate these from my ported Stump Shot Special saws, I begrudgingly named these Stump Shot Super as it started to be a thing and I didn't want folks thinking they were ported, which they are not.
As far as other ported saws go, my waiting time right now is a good two months or so.
Here's a vidja of a "Super" 201tc to see how they run.
