Float level advice, please.

Are you turning the carbs upside down to adjust the floats? That is on the SU video from ztherapy but it doesn't work with the valves you buy nowadays. They were using Grose valves in that video. Those are built different and would not hold the weight of the floats while setting the gap between the float and the lid of the float chamber. The newer needle valves will not hold the floats up. I fought with this for a long time then made my own "float chamber" out of a clear glass jar and set them that way. That's been about 10 years ago and I haven't had to touch them since. They run great. I got rid of the lid with long ears and use two short ear lids essentially turning them from 3 screw carbs '71-'72 to early four screw carbs '70-'71.
