My guess is the lower port is manifold vacuum. The screw next to it would be the idle mix screw. The upper port would be ported vacuum for the dizzy. But, there are lotsa versions of the B and Monojet so, could be wrong....only way to know is to vacuum check it.

Plug any ports not being used since vacuum leaks destroy performance.
