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) .
