Lynn; Today I got to looking into the Weber
48. It has a 180 main, 160 air correction and F-7 emulsion tubes, with 42
mm chokes. Are these figures in the ball park. Looking at the
answers you have sent me, its close.
Also the springs are set up to close the carb
if the cable becomes disconnected. Do you remove these and use an
external spring to keep the carb open or is there
some way to turn these springs around. Thought I had better ask before I tear
into it.
Another question is, do I need a regulator for the
Carter electric fuel pumps. Jegs has one by Quick Fuel which has a bypass
feature and it says that it is for steady output electric fuel
pumps.
It looks like next winter I can install two
high pressure fuel pumps and just flip the low pressure ones off and
switch the high pressure ones on and use the Weber for the throttle body.
I will need to machine two ports for the secondary injectors and weld them
on the intake manifold. Does this sound like a viable solution
for a duel fuel system.
The Wittman Tailwind I'm building has a 34 gallon
fuel tank in the cowl which flows down to a gascolator, then into two fuel
pumps, which are lower than the gascolator, then pumped up to the
carb. Thank
you. JohnD Working on
