        The carb tool will allow you to correct the sooty plugs, but
probably will not
fix your stumble.
        The first thing to do is check the oil level in the carb
dashpots. Most often,
the stumble is a result of low/missing oil in the carbs. If that is not
it, let us
know, and we will be happy to give you a long list of things to check

Listers:
 
My '76 now has a minor but noticeable stumble on acceleration, but only
when 
the car is cold.  For the first 3/4 mile or so, each time I  accelerate
I 
feel it stumble once or twice as the revs increase.  This  habit
disappears after 
that.  I usually use the choke until it isn't  required any more (a few 
blocks).  When I say cold, by the way, the car  never gets REALLY cold,
because the 
lows in Miami right now are about 75 degrees  in the middle of the
night.
 
The only other clue is that the plugs on cylinders 1-3 are clearly
somewhat  
sooty.  The plugs on cylinders 4-6 are a nice toasty gray-brown.
 
The Haynes manual has a procedure on page 65 to set the mixture.  It  
requires a special tool (BMC S353) to adjust the air valve stem in the
dashpot.  Am 
I on the right track here?
 
Thanks.
