[NOBBC] Any thoughts on a starting issue?

[Greg Badano]

Thanks everyone for your helpful suggestions.  I'm going to try a few,
starting with replacing the spark plugs.
 
Best regards,
 
Greg

Take a spray bottle that atomizes
well. Take the car into a dark area
(or at night). When you first fire up the
car, spray the finely
atomized water around the spark plug wires and the
distributor cap.
This will show if the wires are discharging via weakness in
the
shielding as the spark will jump across the water droplets.

The
"Waterbottle spraying on exhaust manifold" will show non-firing
cylinders, but
don't do that to a really hot engine, as the sound that
cast iron makes when
it cracks is quite..... frustrating. But you
should be safe if you do it
within a minute or two of firing up the
engine.

All of that being said, my
first thought was "Sticky Valves", but as
that is actually kind of rare in an
engine that actually runs, I'd
lean towards the "Head Gasket" folks, but spark
plugs are cheap, so
replace those and try it, before pulling the head....
