Calculating the needed size of a single carburetor

Thanks to Mike Tiberio for posting this information on the Yahoo! MGconvert news group.

To figure out how big a carb you want, calculate the cross sectional area of a 32 mm carb (PI × R2), multiply by 2, and calculate from that the diameter of a single carb that could give you the same area...

A 44 mm carb has the same cross sectional area as two 32 mm carbs.
