I did the fuel level test with clear hoses to check everything and got around what i believe is 5 to 10mm (you be the judge pic below) from the seam of the bowl which makes me think its going to run lean, i heard the level you want is from 4mm to 7 right? correct me if im wrong. (i will attach a pic to help you guys out.)
FOR THE BIG QUIESTION or Questions.
1. if i make the floats to sit at 25mm from the bowl meeting surface to the top of the float will that increase of decrease the level of fuel?????? this has me confused as hell haha.
2. how do i avoid a expanded gasket every time i open the carb up to redo the float height hahah
Attachment carb.jpg not found
(all carbs fuel level is in very small deviation from eachother. 1 mm or 2mm )
Thanks in advance.

Measue the level with a ruler and record the level for each carb. I have a 1980 kz750 4 cylined E1 with Keihin carbs and and the spec for mine is 4 +/1 1mm Ithink. You should check your manual.
If the level needs adjustment then turn the carb upside down as in the pick below and measure the float height. If you measure a fuel level of 6mm below the seam then adjust the float height by 2mm and this will give you a fuel level of 4mm when you reassemble. You dont need to do trial and eror. Just once
If you float bowl gasket is a big O ring shaped like the side of a house as mine are then they do tend to expand when you take them off. I put them in individual little ziploc bags in the freezer for about 30 minutes and they will shrink back down again but you have to work fast and with on at a time
Good luck

The tang should be level. If you have to bend it on a angle, the needle will bind. Bend the float arms just enough to have it close, then fine tune it with the tang.
