I have what I think is a late 80's mere 90 hp. The guy I got it from put it on the boat and then rigged up the controls. He put in a new ignition switch. The old switch was on the controls and you pushed the key to use the choke. I am sure it was a feature of the controls hooked to the original motor. My problem is not there is no choke. I can open the engine up and move the controls in the engine the seems to open all three carbs. Should there be a choke cable at the dash and how would I hook that up?
