Still stalling after carb rebuild. ???

The two spring loaded screws that are side by side in the pics are your curb idle (closest to the carb) and your fast idle ( only functional when the choke is on). The spring loaded screw at the base of the carb is your idle mixture screw and should not be all the way in.
Probably more like 1 1/2 to 2 turns out from lightly seated. Ig you've had this all the way in the whole time, Then I'm sure that it would not stay running.
