4150 or 4160?

I just finished rebuilding a 4160 literally like an hour ago and it has one metering block and a plate in the rear with center hung plastic floats.

Rebuild your own...that's the spirit! Don't know if you remember this but we used to rebuild everything--alts, gens, starters, even fuel pumps. Gives you an idea of just how old I am-HA!
