    I'm not sure of the specifications but you need to drop it a little bit for the elevation.

    I believe the manual I got from Mike’s carbs said 1 7/8” from the bottom of the gasket to the bottom of the float at the toe end.
    I will edit to correct if that’s not accurate. I’ll check next time I’m out there with the manual.
    Whatever the manual said, I did and have never run better.

    My Manuel says 1 5/32 but then after skiming through it said 15/32 so Is it possible the 15/32 is from the gasket to the seem in the middle and the 1 5/32 is gasket to the bottom of the float

    After pulling a tape measure out and putting the seam at 15/32 the bottom of the float was basicly 1 5/32 so uh my next question guys and sorry for the questions is how much should I drop my float. Like I said I live at 5500 feet and my jeep goes up to 10,000 plus and the roads are not dirt mostly steep and big inclines full of boulders I was thinking 17/32 any suggestions

    I doubt you need to drop your float. The 2g is pretty hardy for off-road and it takes a lot to get it to puke out into the venturi's.
