My motor when on the water, won't rev out past maybe 2000 rpm at best. The Carb is rebuilt, the ignition system gone through (coils and condesors replaced, and points cleaned and set) New plug wires. The carb butterfly is full open and the base/timing plate is fully advanced. It acts kind of rough and "bucky" almost like it's fighting itself once it gets to that 2000ish rpm mark. The motor has 120 psi compression on both cylinders, the spark effortlessly jumps a 5/16" gap...The motor starts and idles great. If it's worth noting, the previous owner hit something at speed, and sheared the flywheel key, which I've since replaced. I'm thoroughly out of ideas, please help!
