RE: Weber carb adjustment

["Bennett, George J" <george.j.bennett@domain.elided>]

My '78 Spider has Solex carbs and I'm still
using the high pressure Spica fuel pump. The
fuel supply line from the pump goes into a
T fitting. One leg of the T goes to the return
line, sending excess fuel back into the tank.
The other leg of the T goes to the carbs. There
is no pressure regulator. The pressure the
carbs see is just the backpressure from the
return line.
