I have  had the same problem with my1963 200. I too believe dis is reverse lock out too. Don’t advance the throttle when starting too much &  have a new choke butterfly to seat well on the carb body to try  to prevent.Replace the choke spring too to get a tight fit. it needs to be tight holding the bbutterfly tight against the carb body to draw fuel from thr low speed jet too..Some newer straight 6 motors have fuel primers on the carbs for easier starting because of this lean start condition even warm starting.

Those choke sliders need to be spot on to work correctly And what Dave said.
