Calculating the needed size of a single carburetor

Thanks to Mike Tiberio for posting this information on the old Yahoo! MGconvert news group (which has now moved to Groups.io).

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.

Max setup

Thanks to John Engle for sending me these photos and information in a private e-mail.

Single carburetor setup on a Moto Guzzi Ambassador. Work done by Max, a machinist from Clever, MO. Ace Mallot knows Max and reports that the single carburetor setup works well. A standard Dellorto VHB 29 carburetor is used.
