"Open", "closed" Isn't good terminology for SU's The chokes don't work that way. "Up" or "Down" could work better, but not clearly. Pulling the handle lowers the nozzle, a juicy pool of gas forms at the top of the lowered nozzle ready to be sucked up by a cold L motor. Even with Mikunis, "open" would describe when the choke is engaged, as the choke "starting circuit" is open when you pull the handle and "closed" for normal operation. But, "Close the chokes" is still accepted as engage the chokes. After all, the iconic symbol for choke is a butterfly valve closing a venturi. Looking down the throat of all my old American steel, it was easy to see if the chokes were closed.
