1978 70hp Johnson, The spring that attaches from the choke solenoid to the middle carb is missing. Does this normally help keep the reeds almost shut while starting the boat even if you dont engage the choke. The reason why I am asking is that when I start my boat I have to manually close the reeds to about 3/4 closed position to get the boat started, If I dont do this the boat will not start because the reeds will sit wide open which I'm guessing is not allowing enough fuel.
