Adjust float level to 1/4" plus/minus 1/64" from float bottom to casting.
Adjust float drop to get 1/64" to 1/32" between bottom of float and fixed jet.
(hold carb upside down for this). Bend tang on float to adjust this.

This is exactly what I need right now. Just had the boat out and won't go past half throttle or it falls on it's face. Hope setting up float helps as I had it apart and may have bent some things before knowing.
Thank you Sir.
