Then tell me why the set of A12 carbs I just unpacked,center 4392,dated 121 9,original carbs ,never touched since new,never been apart has bowl vent with black vent arm.


I have been doing carbs since the late 80 s, I have received both sets in pieces and those that were untouched from new,like I said above (I have found quite a few A12 without bowl vent but all were early March production) .


I think what Dan is referring to is the WITHOUT bowl vent in his statement does not have the tube. It has the black rubber and arm in the picture. My original question was about a carb with NO HOLE OR ARM AT ALL. What you are saying, Bill, makes sense. I’ve never seen one with no hole so this must be an early set. You answered my question.
