    Losing a cylinder intermittently ‘86 50hp

    yap for a couple /three years the air jet were fixed, my engine idles great with CCMS reeds at sea level. Note: at 1600 to 2000 rpm's my engine heats up 10 degrees or more, always wondered if getting a smaller air jet would help by making it run richer at lower rpm's

    Carbs for 93 70hp johnson

    a quick note, around 93"/94" carb styles changed, 93" 60's were old, and 70's were new(according to parts breakdowns), new style are flat top, and theirs always differing opinions about changing carbs to get 10hp, "i'm not say'n, i', just say'n", good luck and keep us updated

    Stuck at MAX revs 2000 50HP Johnson

    looking at parts diagram, leads me to believe that both carbs are wrong, 2000 50 hp carbs don't have the idle orifice at the top of the carbs like the ones in the picture!
