Joe,
The gizmo on the back carb is a thermal valve to stop vapor locking. It
has a bimetalic strip that opens a needle valve returning hot fuel to the
tank. If you pinch closed the line between it and the firewall you will take
it
out of the picture.
Try pulling out the choke a little or giving the mixture knobs about one
turn richer. The Nissan needles tend to run rich at idle and lean through
the mid range. If they set the mixture at idle you could be having a lean
condition in the mid range. If setting it richer fixes the problem but gives
you a
slobbery rich idle you might want to try some of the British ADQ needles. I
get them from England and can send you a pair.

Does anyone have any ideas? I am guessing I may have a pressure regulator
problem, but is the regulator located in the fuel pump or is it the gizmo
located on the fuel line on the back carbureator right where the fuel line
goes into the rear carb? Could I have a problem with the float settings on
the carb? Is it still likely something in the ignition? I think the
ignition is ok, as it has all been replaced or checked in the last month.
Thanks for all the help. If needed I can take a few pics...
