Topic: Do I need a float level gauge/where to get one..

Here are a couple home made ones. The one on the right is made from an old floppy disc.

K&L Supply Company list an adjustable fuel level gauge
Any shop that deals with K&L can get you one
Given the choice, I've always used a wide steel rule

+1 0n the K&L Gauge..it's very adjustable and was good quality when I got mine in 92'...$32; I modified mine so it will slide over the outer flange raised portion of the carb. body and make direct contact with the gasket surface(after having removed the gasket to get the most accurate measurement)..;I took a hacksaw and cut a slot on each side.

Immortal Here is a photo of the clear tube method and a cheap and easy test stand. Every thing can be set up and tested on the bench. Keep in mind this is for the 78 pd carbs.On earlier models the drain/overflow is a little different. If you look close you can see the fuel level on the #4 carb. It should be 2 to 3 mm below the gasket.

it's basically a spirit level.

attach clear fuel line to the drain plug & bend it up parallel to the side of the bowl.
the height of the fuel in the line = the height of the fuel in the bowl.
this method eliminates confounds like unevenly bent float armatures, differences in float buoyancy,  blobs of JB weld in the bowl, solar flares, etc.

I used the pocket slide rule.  Not easy to find in a store to walk up to anymore.  People in the school supply store will look at you funny wondering what on earth you are talking about.  Too young to have ever seen revenge of the nerds I guess.  Using this, be sure to measure the height of both floats.  Don't think just because you do one that the it the same.
