There are two Weber Carbs that are
popular with Spitfire owners; DGV and
DCOE. Also available are DGEV (DGV with
electric choke) and DGAV (DGV with water choke).
DCOE carbs are sidedraft, meaning air goes
into the carb from the side as original SU's.
DCOEs are higher horsepower carbs but do require
much more tuning. Single or dual DCOEs are
available for Spitfires.
DGV carbs are downdraft; air comes in from
the top like the Zenith Stromberg carbs.
Although they can not achive as high horsepower
ratings, they are much easier to tune often
requiring no modification straight out of the
box.
See this link
for photo examples of these carbs.
