Sorry, all this info is out there, but scattered around.
Here goes.

1) which exact carbs are you using and what metering needles?

These are 3-bolt SU HS6 carbs. I don't know what needles are in there as I've never wanted to risk getting them off center. I have carefully inspected them with a magnifier and saw no scuffs, bending, etc. There are straight and true - whatever kind they are (probably whatever was proper for a B18B - which is what they were on.

2) What condition are the carbs, do the pistons go up and all the way down smoothly and completly, have you filled the dampers with the proper oil?

The pistons move freely without binding. They have been recently removed, cleaned, carefully wiped down and reassembled along with the dashpots. I have Marvel Mystery Oil in them, topped off.

(3) You mention a rebuild, what was done and what parts were used, include any info on if any parts were swapped with other carbs?

They were not fully rebuilt. However, I replaced the throttleshafts with a pair from a could of two-bolt SU HS6s. They fit perfectly and exhibit much less shaft wear than the originals. I also replaced the floats, float valves with proper needle valves (had grosse jets before). I also replaced the float chamber gaskets. The metering jets are original.

(4) Are the lifting pins stuck up or even there?

Yes, they are present and work fine. I usually lever them up with a screwdriver due to their cramped position.

(5) I need to know if the carbs are the early style that uses only 2 bolts to hold the air filters and if yes does the rear carb have a vacuum fitting on the 4 bolt mount flange for the distributor or are they the later 3 bolt air filter mounting style of SU that came on the 1967 and 1968 and if yes do the throttle lever return spring mount on the carb on is it like the earlier style with a spring that goes between the carb and manifold washers and do the throttle flaps have decel valves on them?

Three bolt, no vacuum fittings (I do have those on my HIF6s). No decel valves (thank goodness). The return springs are anchored to washer-hooks on the manifold.

(6) Which exact manifold set up are you using, an early aluminum intake with a single lead exhaust or dual lead fuel injected exhaust manifold, or a 1 piece manifold and if a 1 piece, which one, does it have a 4 bolt access plate near the linkage mount and preheat flaps?

I have the ultra-simple dual-pipe combination intake/exhaust manifold with a single vacuum fitting in the middle of the intake.

(7) Then which distributor is in the engine, does it have vacuum advance or retard?

The distributor is the simple B18 style iron body with an allison/crane electronic ignition. No vacuum retard or advance.

Whew, I hope that gives you a clear picture of my setup.

The B20E in this car was installed in November and came from a 71 1800E. It originally had a B18B. I've alternately run these HS6s and a pair of HIF6s on both motors with limited success. I've had trouble especially with the HIF6s and had decided to switch back to the HS6s due to more community knowledge and fewer troublesome subsystems.
