Essential for preventing overflow or fuel starvation. Measurement is typically taken from the gasket surface to the highest point of the float.

Manages the mid-range (1/4 to 3/4 throttle). Essential for preventing overflow or fuel starvation
Usually set between 1.5 to 2.0 turns out from lightly seated. Turning clockwise decreases air intake for a richer mixture; counterclockwise increases airflow for a leaner mixture. Usually set between 1
