Berny, you need to check "fuel and fire."  I have had similar problems.  Most
of the time it was the ignition; only once was it the fuel pump.

First disconnect the fuel line leading to the carbs, put a small jar under it
and crank the engine.  If fuel spurts out your pump is OK.  Go to the next
paragraph to check "fire"-- meaning the ignition.  If no fuel spurts out, then
the pump is the problem.   If you have an original pump there is a small lever
on the pump outboard of the engine.  Pump that and see if gas spurts out into
the jar.  If it does then check to see if the pump is connected properly to
the block and if the lever that goes into the engine is seated properly.  Then
follow Malcolm's post.

Next check for fire.  Pull a spark plug wire off one of the plugs.  Hold it
with an insulted pliers or a heavy glove and place the tip near the block.
Watch out, it will bite you if you become the ground.  If you do not get a
large spark, then the ignition is faulty.  If no spark, take the distributor
cap off and look at the points.  Are they pitted or misadjusted?  Check the
wires inside the cap on the plate.  There is a small plastic cylinder which
goes vertically through the black and orange wires.  If this is broken it will
short out the points.  (This cylinder is over the screw to which the "lever"
from the points is connected and to which you hook the wires).  Check the
other black wires inside the distributor.  If any wires are broken or worn,
replace them.  If the points are pitted or misadjusted or the plastic is
broken, change the points and the condensor.  Be careful to gap the points
(.025 if you are running a regular coil).  Next check the distributor cap for
cracks (or tell-tale tracks) from the center connector to the outer
connectors.  If you see "tracks" you need to replace the cap.

That's a start.  Let us know what you find when you test for fuel and fire.
We'll go from there.  Cheers.
