Okay, I figured it out. When I select cart start #25, then I use the same bottom button to start the plane I hear the shotgun and then it starts. I guess when you select elect
or cart start, the bottom start button is automatically configures as a elect/shotgun start. I had it set in elect start and lowered the #25 knob to manual start then tried the upper
button and there is where I realized what was going on. That one lower start button acts as a duel purpose start button when you either select #25 to elect or manual start.
That one start button acts as either elect/manual starter button based on which setting #25 is in was not clear enough for me to pick up on. The upper button is moot and will not
function as a starter button. Don't know why two start button were needed when the bottom one will convert to a electric switch or manual when you select the type of start you want (#25).
So I have had my Ah ha moment and all works well.
