This should be a near-first step. As I recall the problem occurred 
while the engine was running on fast idle, rather than idle, it 
could have been taking too much fuel (junk in a float valve, etc.) 
but was idling fast enough to load up the plugs before the rich 
mixture killed the engine. Do pull the plugs and check them to see 
if they are black with soot and/or wet with fuel.

Since the re-start symptoms include fuel spitting out of the 
intakes, this might actually be a fuel problem and an ignition problem.

Also, as Randall mentioned, you really should remove the distributor 
cap and check for proper points opening. IIRC, mention was made of 
using a voltmeter to check points opening, and that the timing was 
set where the voltage dropped. When the points are open, the coil's 
connection to ground is interrupted (no current flowing, so voltage 
reads high) and the voltage drops when the points close because the 
points are, effectively, a short to ground.

It's possible that, in an attempt to fix the problem, the timing's 
been set on late side of the dwell, which would retard the timing by 
40-odd degrees--enough to cause the spitting back on firing.

Cheers.
