the screws are just the idle. wind in fully and then back out about 2 turns. there is a given figure that i cant remember. about a turn out start the car and then adjust then the same to give the smoothest idle. not really possible if you have a cam that needs a weber car.

It could be a drilling or the idle jet obsured with a drop of water or muck
The actual jet needs taking out of the holder too, the hole is not very big
You can try blowing back through the drillings with an air line
Its one of those if you see it you might know what it was, a strip clean might cure it.
Could also be an air leak on that side
