Have my project boat out on the water and it's running at 3/4 throttle. I adjusted the cable as far as I could but didn't help much. Now I see the linkage leading to the (toggle) on the side of the carb that has a roller, this speeds up the engine really nice... yahoo! fast. I can pull the plastic pin and cotter pin and turn it out. Is this what needs adjusting to get full throttle? Engine was a new fit on a different boat. 1972 ESL 50 hp. Johnson.
