This problem of yours is bugging as much it is no doubt bugging you. It appears to me it is either not enough fuel or to much air. On the point of not enough petrol is the top of the float chamber properly ventilated thus allowing the correct atmospheric pressure to press down on the fuel in the chamber and thus get the correct amount into the jets. My reasons of thinking this out is. If you are only getting a small amount of fuel then by closing the choke you only get a small amount of air (the balance between the two are correct). Push in the choke and then to much air is introduced ( all out of balance) the engine stalls.
There is a vent hole some where in the top of the float chamber casting check it is nice and clear. Looking at a a drawing of your carb it looks to be somewhere around where the needle valve screws in and exits in the hole on the top 90% to the fuel inlet I may not be quite correct on where it is the picture is not that clear.
