The specs call for a 1/4 inch dimension between the bottom of the float and the base of the carb, with the carb upside down. Where on the float do you reference the 1/4 inch dimension (outer edge, center of float,?)<br />It then calls for a measurement of 1/32 to 1/16 from the bottom of float to the main fuel jet.(Carb right side up)<br />I assume this time it's from the center of the float, but where is the reference on the main jet. (center of orifice, top edge of jet body,?)<br />Also, in my rebuild kit there were 2 different inlet needle seats. One with a fixed end and one with a spring on it. The original seat had a fixed end. Which one should I replace it with?
