Me thinks you are mixing up parts on this carb, I have a number of different year Holley #1850 and all of them I have use the same needles and seats as most Hi Po Holley carbs. have scope
The original 1850 made for Ford OEM motors has two fuel transfer tubes, one big and one little one. The later 1850-1 with the unervisla throttel linkagesand up to the latest one I have, 1850-5 have one fuel transfer tube shruggy They all have side hung floats like you pointed out up
