Okay, now we have information we can understand. So after choking, gas comes out the FRONT of the carb. Like Frank said, that’s to be expected. If the engine is lean-spitting after it starts, gas will still kind of blow back out. Where do you have your high and low speed mixture adjustments pre-set? On my 15s and 18s, I usually start with both needles lightly seated, closed. Then I back out the top, low speed one about 1 1/2 turns and the bottom, high speed one, about 3/4 turn. This usually will result in a too rich, but easy-to-start, condition, that may run roughly but NOT sneeze back, and no gas to speak of, should come out.

you can always kill it with an external  stop switch (button)  hooked into the points… shorting the points   may  held reduce excess fuel drips from choking/tilting

Not trying to “muddy the waters” here.  Is the engine running on both cylinders?  If not, perhaps fuel is being blown back out the front of the carb because one of the reed valves is broken/stuck open slightly.  Like everyone has said, some of this drooling is to be expected on a normal running engine.  It is hard to know without actually seeing what is going on.  I don’t want you to go crazy over something that is somewhat normal.

I guess I would start with figuring out why the engine is running poorly, this might just solve the drooling issue

gas spurting up front can only come from a  carb overflow   or spit back due to bad reeds but yours  being more liquid than vapor I would suspect  the carb … cyl head is to far away  to cause the problem … imho anyway  .
