You mean how do they arrive at what size to use on a specific model or where they measure from?
If it's the measurement it would be the inside diameter of the front of carb throat I think.
Larger diameter is better for top end, smaller for low end.
verner cliper measure on the intake side side of the carb-the smaller non flared side.
