My 68 Evinrude Starflite 100s #3100883b stalls at very slow speed. Starts great, but after a run up the river it gets warmed up and it stalls at very low speeds. This in turn creates a big problem with the electric shift not be able to do it's thing.<br />It runs great at mid to high speed.Can anyone suggest where to start. The carb looks very new , A year or 2 at most.I have a Selco book but a'm not to proficent at all. thnks
