I have a Holley carb with the List # of 4223 and cant find it listed in any info on what this thing is.Its very different from others Ive seen,low rise choke horn with a funny looking bracket crossing right to left,center squirters,primary and secondary flaps open at the same time,also has vacume secondaries.It is obviously an older carb.
Thank you for any help.
