    Boat test went well, other than the wind. I traveled at least 8 miles. Got the high speed running best at 3300-3700 RPM. This is on a 12′ Lund. Got the slow speed set to abot 750 RPM. Any lower and it would die in a couple minutes. Good enough for this 90 PSi compression motor. Fleetwin,when you said "highest smoothest sustainable RPM and then back off 1/8 turn you mean turn the knob counter-clockwise,richer,correct? That’s what I did,don’t want it too lean. Runs great ,I thought I would get more RPM at top speed though. Thanks.
