Whats a governor/whats that aluminum-covered thing between my carb and intake manifold?
Governors were available on the later split-window busses; they operated by a spring loaded vane, which kinda looks like the choke. When you enough air/fuel mixture to overcome the spring tension, it cut off the flow, at which point the spring pulls the vane back again. You can adjust the spring tension via the adjuster at the top – tighten to allow higher speeds, loosen to cut in earlier. The governor is put together with special screws with holes in the sides of the heads, through which a wire was run and clamped with a lead tamper-evident seal.
