Not to beat a dead horse....but pairs of plugs fire at the same time
as the ends of the coil secondaries are tied to two plugs.....inners and
outers. I would think that removing a plug wire would open the secondary
path and kill the other plug.   ???

.....unless of course by holding the plug wire you are completing the path. ;D

...hey heavy, on the racing idle, you said you synced the carbs...did u use a sync gauge or just bench sync?  My 78K carbs raced like that after I rebuilt them, and I finally adjusted the needles down, and that will bring the idle down.  As someone mentioned, you need to get yourself a sync tool to do it right.  That will also help with the slow return to idle...

I did use vacuum gauges to synchronize the carbs.  I couldn't get each carb exactly perfect, compared to the #2 carb, as it seemed like if I adjusted one carb, it would change the setting on a different carb.  I was able to get them all pretty close though, and called it good and put everything back together.  I'm not sure why, but on the gauges the readings were around 5 at idle, and in this range on the gauges it says "check for vacuum leaks".  Should my readings have been higher????

Its just that when  I rev up the engine, sometimes I have to push hard forward on the throttle to bring the engine down to idle speed.  I"ll have to investigate some more...check for manifold leaks..etc.  I lubed the return cable and the cables seem good so I don't think its poor cables, but maybe I should just replace them to be sure.

 You should check for vacuum leaks . If you are using the original intake boots(manifolds) you are probably sucking air which will jack your idle up.
