Default Re: Float gauge for Holly 1901 carb

Ok, so I am taking a few measurements. (I have a few of these for back-up, and I though I would get the gauge set first. When you say "5/32 measured from the top toe of the float with the float all the way up", that would be picture #1 below.

When I measure the "actual FUEL level is it 1 1/16 ", measured from the bottom of the bowel, not 1/2". (picture #4) Am I measuring from the wrong location?

I am using water for the measurements and photos.
