    Sure, I guess those sizes may be helpful. I have 70's and I thought they change by 2 at a time, although Ive tried 82.5s and 77.5s. I guess they change by 2.5 eh?

    I was under the impression that the size was the orifice size in mm, but beerdart said that it's cc's/hr. that's all I know.

    It would really be cool to have huge stock of jet sizes to choose from, both pilots and mains. I have a feeling I'm gunna need to test a bunch.
    I know they are precisionly drilled w/ a taper bore, but I'd like to be able to drill them for testing, and purchase the needed sizes.
