    I am not at all familiar with these engines.
    The 140 is on a 1979 Sidewinder that it was sold as a package when new. It does have power trim and the stock prop. I don’t know the pitch off hand.
    I will take a closer look at it next time that I see my neighbor at the cottage. He just recently mentioned that he felt that it lacked low end power. WOT seems OK.
    Is there a specific point when the carb butterflies should open?
