After valve adjustment stall issues.

Timing is good. I am getting an immediate stall when it’s in gear and I drive then stop. Adjusted the carb idle and same issue. When I accelerate it feels almost as if the engine is under load (like pulling a trailer).
Saying the timing is Good, only means something to you.
Some to all of your symptoms could easily be caused by retarded timing.
You do know that your engine has at least THREE timing requirements, right?
It has one for WOT Power,
One for part-throttle acceleration and power NOT at WOT,
and one for Part-Throttle cruising.
The Idle-timing is relatively meaningless and for the most part is just a fall-out from the other requirements.
For example;
>At full power after 3600up, she might like 32 to 36 *
>At stall rpm, she might like 20*
>At hiway cruise she might like more than 48*
IDK; I'm just guessing.
>At idle, your slanty will idle smoother the more you give her, up to around 24*. And will have more power as well. But it s unlikely you can set her there and not have other issues like, detonating at WOT, under say 3000.

The very first thing I would look to is the float level. and the second is the transfers slot exposure underneath the throttle(s); which should be obviously taller than wide, and return the Idle mixture screws to 2.5Turns out.. and the third thing is checking the PCV system for full and proper operation. Ok wait, since the PCV is the easiest, I'd do that first.
