When I did a first fit of the cowl section today, I noted that the choke rod would be bound tight if I would push the bracket through which the choke rod passes far enough forward to bolt to the cowl. I assume the choke rod needs a bend some six inches forward from the bracket–safe assumption? March 24, 2015.
If you are referring to the choke rod on a TO-35 make sure you have the metal bracket/choke rod support, and make sure it is correctly installed and not turned slightly. It will also cause the rod to bind.
