Hi I have a 1997 Evinrude 9.9 pull start model# E10REUS. It starts, runs, idles, fine up to 1/2 throttle then it wont gain any power and cuts out, quickly ramping up RPMS daaaaaadadadadaaaaaaadaaaadadadadada. Sounds something like that!
I have ruled out fuel problems, complete carb rebuild with 30+ hour soak in carb cleaner, poking out all orifices with copper wire and blowing out with air. The fuel pump is operating normally. There is no improvement when squeezing the bulb, choking, putting fingers over the carb throat, or squirting gas into the carb throat. The connections and hoses are all brand new and air tight. The carb float is good and is not restricted in any way and is set to level with the carb inverted. I even tried it slightly angled toward carb body to have more gas in the bowl, with no effect. The tank vent was open. Plugs are correct and gapped correctly.
Please help! I have family on the way and I'm supposed to take them fishing!
