    Dr Tom:

    Once again you need to realize that this isn’t the acadamia world you’re immersed in!

    I have no idea other than it means we can cheat, right?

    I’m assuming the section you quoted is in TAG, and again I’m assuming it refers to butterfly carbs.
    The arm and lever I expect is mentioned because they want to allow fixing the tillotson weakness of the mounting point coming off the end of the butterfly arm. The reason they say arm and shaft remaining standard is because they do not want to put a special high flow butterfly and shaft mechanism in it’s place.
    I’d say the washer reference is also to the tillotson type carbs where some people like to add washers between the needle jet and carb body to improve sealing. Also, if the carburettor is set up so that you need to have a number of turns out on the jet they are a help as otherwise they have a tendency to fall out.

    PS you can also weld a washer to the slow running jet to allow you to tune it whilst out on the track….! ! …that’s probably the obvious one……..
