Thanks for taking the time to help. I just bought a 1990 model Force 90 HP. Please forgive me. With the engine dead. When I shift into forward and push the control to full throttle the butterflies on the carbs are only a little more than half open. I have ordered a Seloc service manual and will go throught the settings when I get it, but I am curious is there any chance the throttle is not supposed to open all the way?
