Float height adjustment - am I doing it right?
« on: April 09, 2015, 12:28:10 PM »
Should I measure float height (16mm per factory manual) between the carb body and the line on the float?   Or is it asking me to measure from the carb body to the very tip top of the float (kinda hard to do since it angles up like a pyramid!)

Found out this is how it's supposed to be measured:

More important would be the actual fuel level measured with a fuel level gauge.  I set my (98 kx250) float height based on the manual (clymer) @the same 16mm.  It was previously set much closer to the carburetor body (higher fuel level) and after 2-3 laps of practice @ my local 1/4 dirt track the engine would not pull because of a lean bog.    In between practice and heats I had to raise the fuel level to where it was set previously then all was okay.
