Many plastic props don’t
work as well cause the blades bend and reduce
pitch.
SS props are “Better” than
aluminum because the blades are thinner.
However it used to be thought that if you hit something real substantial like a rock, and aluminum prop would bust a blade, but the
motor gears would survive, where an SS prop would bust the gears in the foot.
Keep your old carb, I still think you just have the float level set too high.
I’ve never yet seen a carb that I can’t successfully clean, although I have had to resort to an ultrasonic cleaner at times, which I did not bring with me on the
boat.
I wonder why the
Honda generators don’t seem to suffer the same carb problems?
