Why does it do that? 150T

Gave the little top handle a work out today. trimming trees, 45 foot manlift, lotta fun. No pics, I should have taken some!

Ok, almost stock. Muffler mod, and advanced the timing a smirch. Runs strong. More often than not, let off the trigger and it dies. if I remember to blip once on deceleration, it will stay running nicely. what is it?
A touch lean?
A touch rich?
Idle sounds about right... I don't run the saw all the time, but there are times like today where that was the tool of choice!
Thanks in advance for any insight...

Did you defeat the BS EPA stop on the carb so you can get full adjustment from your carb H L. I cant recall if there was a tab on L or not to trim off or what to get full adjustment. GL
But one I had tuned after muffler mod never acted like that.

didn't seem that I messed with my carb, yet.
It is close... but evidently not perfect. I will look into defeating the limits on the screws, if I am against the stops

Initial assumption would be it’s too rich.
