[Healeys] Idle dies

What kind of a fuel pump, age, location?  Obviously something is making it lean out when warm.  Points of the fuel pump?  Maybe put a fuel pressure gage near the carbs and let it warm up, then move it near the pump.  Or just let it warm up, then shut it off and remove the fuel line to the carb and see how much fuel is coming out in a bucket when you turn the key.  If plenty of fuel, then you need a heat shield under the carb bowls.  My .02, take it for what it is worth.

 idle is up to 1100 RPMmixture has been leaned and richened,.,,,we have basically rebuilt or replaced everything except a new distributor. Pulling the choke cable out a bit, keeps it from dying. (This should indicate a lean misture, but that has been checked). It idles fine for awhile, then slowly drops off and dies

Revs, eh?  I had a similar problem with our BJ7.  My best guess is
that heat is leaning out the mixture or changing the throttle opening.
Have you tried just raising the idle a couple of hundred revs (or
toms)?  Maybe richen the idle mixture a bit?
