Default V12. one bank lean, one bank rich???

Hello.
Ive been re-assembling a 1976 xjc v12 from boxes and boxes of parts, what was a completely empty engine bay (no wiring, nothing...) now has a running motor. which is good.
first started with 3 injectors not firing, replaced amplifier and runs, idles, revs well etc.
But, the r/h bank has all white plugs and is running HOT compared to the l/h bank, running all sooty plugs.
This is prior to any cooling issues/ thermostats/radiators etc.
Ive not run it for more than a minute at a time so far.


Anybody experienced this problem?


Cheers,


Stephen.
Melbourne

Stephen, found ya.

I answered some of the fueling in your intro post.

Have a read and ask away if more is needed.

These are simple systems, so we must think very systematically, and simply, or we are all buggered.
