Weber Downdrafts

["Don Toy" <dontoy@nb.net>]

My 1980 MGB came from the PO with a weber down draft and headers. My
problem is this: is it necessary to plumb the water through the intake
manifold below the carb? Was this water connection just a function of the
choke on the original carb or did it also serve to preheat the air / fuel
mixture? Can I reroute around this with one piece of hose or keep it as is?
Thanks in advance.
