Retiredoz,

you may be right . I am guessing your talking about the cup seal being not used in 79? I do know that it seems like the carb was changed 3 times in a serious way for basically the same power head that was used on 9.9s from like 75 to 91ish to 95ish other than the ignition systems going from points in the 75 then 85 and 91 were also different from each oher I am guessing both were a type of cdi type set-up for 85 and 91. I couldn’t tell much of a difference when setting up the motors regarding ignition systems other than getting the timing of the carb butterfly opening at the correct time with relation to the magneto plate rotation. The big difference to me on slow engine idle was how well the 95 carb performed much better than the 75 85 and 91 carbs.
