Ellis – don’t know if this will help you or not on the carb setting but here’s some pics showing the carb on my ’57 Sea King. With the carb installed on the motor as shown in this picture, the carb needle was open a little over 1/2 turn from the fully closed position. It looks like your carb knob is installed correctly onto the needle, but you need to check to see how much the needle itself is actually opened from the fully closed position. On my motor, this needle open just over 1/2 turn is how I found it before I dismantled and cleaned the carb so I just put it back in the position I found it. The motor ran really smooth without having to make any adjustment to the carb once it started up. Did you remove and clean your carb?
