I think I have it figured out.
That bowl vent clip was sorta key. There isn't one in my carb, but probably supposed to be there. The accelerator pump was working (knew that before because saw gas being squirted in), but I think was probably adjusted so that it was flooding the engine.
If there were the bowl vent would have been wide open and it would be obvious that it was adjusted way off, based on the instructions in the service manual, the bowl vent is supposed to be 1/16" open with throttle completely closed. But with the clip missing, you keep thinking "what F**ing clip? My bowl vent doesn't lift at all"
Those little notches in the accelerator pump are for a clip that will hold open the bowl vent slightly, like 1/16" when completely close, and I assume, when accelerator pressed, closes completely.

Now look at where those clip notches are when my throttle completely closed. Like way too high.

Moving the accelerator pump rod to the outside hole of the accelerator pump rocker arm moved that 2nd clip notch (which is where the clip should be when the accelerator pump rod is in the middle hole of the throttle lever much closer to where it would be lifting the vent 1/16" when completely closed.

I took it out for a spin after this adjustment and it performs WAY better. It still stalls a little if I really step on it when stopped, but I also think I have more like 1/8" between the bowl vent and that second notch, so I need to do some bending of the accelerator pump rod. Also, pretty sure I need that clip. I had a rebuild kit with instructions that show what that clip is supposed to look like, and its definitely not on my carb, but at least I know what its supposed to look like now. I'm not too sure what that clip does though, other than to make it easier to adjust the accelerator pump.

Thanks all for the help.
