Hi Tom,
Still trying to figure this out.
You said "Rea was full of gas-----front only 1/2 way up."
Well in my experience the needle valve closes when the fuel level is the
equivalent about 1/2 way when the float is removed.
My method of checking float levels is a little unorthodox but pretty
accurate.
Presuming that the carbs are not so hot that the float chambers are
boiling, shut off the ignition when the engine is running badly and coast
to a stop.
Remove both suction chambers and the piston and needle then use a small
twig or even a pine needle and dip it down through the jet to determine how
far down from the bridge the fuel level actually is.
The only times that I have encountered a significant difference in the
levels is when there was problem with the pump, the float had sunk (in that
case fuel flowed out of the jet with the ignition on), or a piece of rubber
from a frayed fuel hose had somehow got past the filter gauze and jammed
the needle valve open.
In my experience a 2 carb engine running on one carb displays very
distinctive symptoms. Usually idles fine, although slowly, and can actually
be driven quite satisfactorily albeit significantly down on power.
If the throttle plate is still opening the loss of power is more apparent.

The design of the union on the carbs is such that the carb first in the sup=
ply line will hog fuel from the 2nd carb when delivery is limited.<br>
<br>
First do a delivery volume check from the union at the 2nd carb. Then compa=
re that to the same check to the first carb.<br>
<br>
I=C2=A0 suspect that you will find that total supply is insufficient.<br>
