[QUOTE="LionHeart, post: 435742, member: 22379"] Tried trim setting on lowest and second lowest position with no change. Motor, trolling motor, battery, and myself were all in the back of the boat. 150 lbs. passenger and 15 lbs anchor in the center. Choke opens and closes fully using adjustment knob but throttle seems to only open around 80% using throttle (i can open it fully by grabbing the roller and pulling it forward) Hope this helps you guys help me. I bought this motor used and was told it had been sitting in a garage for couple of years. Carb was filthy so I rebuilt it. Replaced spark plugs just because. I noticed a screw on what looks like a cam that meets the throttle roller. It was backed out fully. Tightening it seems to extend part of the cam that meets a roller on the throttle body. It honestly seems that if the cam could advance further, the throttle would open more, but I see no way to do this. Still trying to learn what everything is called so bare with me. Totally new to all this [/QUOTE]
