Fred:

What carbs - HS6's?.  How did you check the fuel flow?  I assume 
disconnecting the fuel pipe at the front carb and running the fuel pump 
momentarily with the disconnected hose emptying into a suitable container.

Let me know and I might have some suggestions for you.

I have driven my BJ7 several times this week.  Each time I drove the car,
there was a noticeable lack of power.

The car slows down when climbing long hills and will not accelerate at all
up them.  On flat sections, I could not get the car to accelerate at
anything more than a modest amount in fourth gear.  It was somewhat better
in second and third.  If I engage overdrive, the car will cruise OK on the
flats but drop out of overdrive instantly when climbing a hill or pressing
the accelerator.

I have checked everything (I think).  New plugs, cap, rotor and wires are
OK.  Valves are set properly, timing is right on and advances when the
engine RPM goes up, no wobble in the shaft.  I have a Pertronics replacing
the points and have had it installed for years with no problems.  Carbs
seem to be adjusted properly with an air flow meter.  Chokes are not stuck
open.  Fuel pump and fuel flow is great.  The battery is in good shape
fully charged and the alternator is charging just fine.

I am using the highest octane ethanol pump gas (93) and I know that has
some impact on drive-ability.

I have looked on line and am considering an emissions tester.  Moss sells
an O2 sensor called the Exhaust Gas Analyzer but it measures only O2.  Moss
also sells  a Wide Band O2 Sensor Controller (I am not quite sure of the
differences) that requires an oxygen sensor to be installed.  Is one better
than the other?

For those who have used one of these devices, or something similar, what do
they really do and can I get the car set up properly with either of them?
Is there an alternative that I should consider before considering either of
these options?  Will these types of devices allow the proper air/fuel
mixture to be accurately set.

Any information and guidance in this arena would be greatly appreciated.

Thanks in advance,

Fred
