Re: Topping out at 20 mph...Too much fuel ?
Well if it was foaming of the gas then keeping the bowl empty would have no gas to foam, but that is just a guess. I just know mine lost power at was once there and I fixed the air leak then when my motor mount got just bearly loose I lost power again, thighten it and fixed the problem and my logic was all wrong with my thoughts of the carb being the problem. If your jets are the same and your float is working back the way it was before you replaced it, then it must be somewhere else then the carb it's self, I would think. These little motors are tricky even if they are simple. Best of luck and let us know the fix.
