I am not sure if this is the only difference, but I have had both on my engine and the 4160's were vacuum secondary, single inlet carbs. I currently have 4150's and they are DBL pumpers and mechanical secondarys.

4160s use a secondary metering plate. 4150s have secondary metering blocks.

The 4150s can be mech or vacuum secondaries.
