Recently I have had a cold start flooding condition and after reviewing some information I have come to realize that my choke butterflies are adjusted incorrectly. I have the electric solenoid with a thermal switch on the motor (a 1970 60 HP ESLD). My manual states to loosen the two linkage screws and manually close the butterflies, which I have done. When the key is in the "on" position my butterflies close fully through the electric solenoid spring and plunger. This is causing cold start flooding. I have seen posts where it states that with the key on the butterflies should close only half way. Do I make up this adjustment in the plunger adjustment or on the choke linkage arms?
I have also seen the bulletin where you disconnect the thermal switch completely allowing you to operate the choke manually with the switch at the controls. I have replaced the new thermal switch along with the thermostat so I am trying not to modify the bulletin. I feel as long as I know the parts are working correctly, I should have no problem. But I am confused on where to make up the cold start choke butterfly adjustment.
