If the roller was smaller than spec diameter, the carbs would open less and later than spec, so yes, lean and late. If the tape/hose or whatever was LARGER than spec roller diameter, the carbs would open MORE and sooner than spec, so I would expect that to burn more gas, but less likely to hurt the motor. Lean would reduce power, might make it run hotter, and could lead to detonation/pre-ignition which can be fatal pretty quick, as you mentioned. When I rode in your boat during our prop trials, it didn't seem to me that you were down on power that much compared to my motor, and if it was lean, you might have had problems by now. I'd bet it's running a little rich (and thirsty!) Did you ever get a factory manual for that thing? It has good pics of the throttle linkage/rigging. Denny
