I need help identifying an old carb that I have. It has the "smooth" style air horn (typical of truck?), nozzle bars that are high in the middle, vacuum port and a spark control valve. The throttle base has the hole for the vacuum and is setup for a choke cable with a bracket attached to the lower middle section and on the other side of the base, a ball lever. The throttle base has AA-1 marked on it, no marking in the circle and 94 on one side. Oh, the little accel spray bar has a #70 on it. Please help. Thanks. <!-- / message --> <!-- controls -->
