Your ’64 CD has a non adjustable fixed size orifice jet, #67, instead of a needle for the high speed circuit. The low speed circuit is adjustable and the adjusting knob is in the lower pan, next to the choke knob. The ’63 CD’s were the last of these motors with two adjusting needles. Your motor may be missing some of its parts.
