If anyone could post a)a pic of an air bleed with the screws labeled, and b) a link to the TH .46 manual with air bleed carb it would be really great.

Sounds like both the barrel stop AND the mixture screw need to be adjusted? I guess I need to find a starting point and know how to adjust these, and in which order.

If it is the same as the 46la please let me know, and I will just look at that manual online.
