Thanks for all the suggestions to date.  Have followed up on most of
them. May have a new symptom related to the flooding problem. Engine
stalled at a traffic light while idleing about 30 seconds.  Started OK
but as I drove off, saw the tach was jumping around at random from about
2500 to 4800 revs.  The engine speed was normal and the tach settled
down after about two minutes.

I have installed an Equus electronic tach with a clock feature.  An
aftermarket.  Had it on three different vehicles over fifteen years and
never observed this happen before.  The tach uses the same "green wire"
connection off the coil as is shown in the wiring diagrams.

Any idea if this could be relevant to the flooding problem mentioned
last week?

Second question.  About a month ago, just after I changed anti-freeze
(of course) noticed a whine in the water pump which was only confirmed
with a stethescope.  Now the whine is clear without a stethescope.  How
long can I safely run Smoky before having major problems?  Would not
hesitate to change now but Chri$tma$ is coming and I am looking at an
engine swap.

TIA

Earl
