Hallo, I would like to ask again about the air-ballanced carburettor.

I suppose I've misunderstood that so far. I thought an air-balance carburetor would have a different underbody with an internal channel from the float chamber bore forward to the air intake (yellow). I think now that's wrong.

Is that niw in the following right:
1) I close the hole (red) in the float chamber.
2) I file a 2/10 inch wide open channel between float chamber and venturi.

Then this is right for air-ballancing?

Thank you in advance.
