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.
