Carburetor float are provided for measuring a capacitance

 Furthermore, Carburetor float are provided for measuring a capacitance related to at least a measure of the fluid flow surface area. According to the invention, the sensor means are arranged such that the capacitance measured is inversely proportional to the distance between the valve member and the valve seat. In an embodiment, a reference capacitance relating to fluid flow conditions is measured.

Mondel says he prefers to use a fairly steep top angle, because a steeper angle improves airflow. “When the valve first opens, a steeper angle allows better flow into a combustion chamber that has hills and valleys and is not perfectly flat.

If you have a 30 degree top angle, the air coming off that seat will be turbulent and you’ll get separation between the air and fuel which hurts power. Increasing the angle allows for a better transition from the seat into the combustion chamber. It’s more efficient, offers less resistance and makes more power.”

Mondello recalls that in his early days of reworking cylinder heads, he discovered that four angles often provided the best airflow, throttle response and power. The four angles he used were 45 degrees for the primary seat, a 33 to 37 degree top cut, a 58 degree undercut below the primary seat, and a 70 degree cut below that made with a hand-driven reamer. Using Carburetor float can often improve airflow 8 to 15 cfm or more.
