First thing to determine is what kind of smoke.

White smoke (actually steam) implies water 
(coolant) is entering one or more cylinders.
Being steam, it dissipates quickly.  Causes 
include bad head gasket, cracked head or block.
Usually most noticeable immediately after 
starting the engine.

Blue-white smoke implies excessive oil is being 
burned in one or more cylinders.  Causes include 
bad piston rings, valve guides and valve stem 
seals.  This smoke tends to hang around the longest.

Black smoke implies too much fuel.  In a carburated 
engine, causes include choke not opening properly, 
carburetor float level too high, carburetor float 
sunk and gas from carburetor float chamber entering 
intake manifold through some non-standard path (such 
as loose screws, loose jets, a crack in the casting).

Once again I'm having an engine problem with the 235 I-6 in my '54 1/2-ton
that goes beyond my limited technical expertise.
Driving from school to work and, later, work to home, two days ago, I
noticed some smoke coming out of the tailpipe and general rough running.
I took a look at the spark plugs, and they were all covered in soot, but
nothing seemed to be wrong with them, so I wiped off the soot and put them
back in.  No change in how the engine ran.
Yesterday, I took a look at the points, they looked clean, so I re-gapped
them to .016"...and now the engine is running even more rough, with more
smoke, and it won't stay running without giving it a lot of gas.
I did notice that the screw inside the alternator that holds the points at
their set gap (not the one that adjusts the gap) just keeps turning; it
doesn't tighten.  I'm guessing this is not normal?  Could that be the
cause of my problems?  Any other ideas?

Thanks in advance,
