[Healeys] which carb set up?

[Oudesluys]

48mm Webers are far to big I think. Use 40mm or max. 45mm Webers / 
DellOrto's with chokes around 32mm resp. 36 and proper jetting to be set 
up on a rolling road. If only used cruising on the road get 40mm Webers 
/ DellOrto's with 28mm chokes to avoid drivebility issues.
There is a great book for these carbs:
How to build & power tune Weber & DellOrto DCOE & DHLA carburettors by 
Dess Hammill.
