    21mph!! 5,050 RPM. 21mph was my top speed, I’m running 19mph most consistently at 4,950RPM

    congrats! What do you credit for the improvement?

    The fixed jet style carb was running too rich. I swapped in a bowl with the adjustable high speed circuit and tuned it on the water. It’s now faster, uses far less fuel and doesn’t have tons of unburned oil dripping all over the place.
