I got a little fed up with trying to use calipers on the rounded surfaces of the float chamber and float itself so I snipped this little deal out from the plastic cap of a vitamin bottle.
There are probly several ways to fab this thing but I started with a carb that was already adjusted and checked at the 17mm wet level. Then filed and clipped with scissors until it fit.
The notch on the left side snugs up against the jet block, the tip on the upper right corner aligns with the carb body, inside edge....then adjust the float until the bottom edge just touches the flat part of the gauge.
I always do a wet level check just to verify but have not had to dismantle and re-adjust any carb since making this.
