That's interesting John. Now I've got to speak up and my twists to this
situation.( OK )

I've been monitoring this thread because I have similar issues after my 30k
miles service, and leaning my car out. I've probably leaned it out tooo
much, but I was trying to find out why I only get 15 city mpg; how hard I
drive makes almost no difference.

( Typically, The 02 setting can be adjusted when running to rich to
compensate for the 02 sensor age.It should be changed out at the 30,000 mile
mark or sooner if it's been abused by over enrichment.) But, if your warm up
reg ( cpr ) is not putting the pressure on the top of the control plunger in
the fuel distributor, then your trying to adjust one to compensate for the
other. Meaning you can't adjust the 02 to make up for the CPR pressure. I
would replace the CPR and the 02 sensor then readjust and you should be back
up to the 21 MPG +. Results to me based on what were talking about you would
run to rich.)

Early morning or four hour parked starts smell very gassy and run rough,
almost bad timing-like. I did have a bad vacuum hose on the timing advance
unit, but that is fixed. I'm thinking something else is losing vacuum and it
takes time to build it back up after starting? Say the system loses vacuum--
how long does it take the system to get it back up? And if you lose vacuum
in one part, does it effect other parts, like the air mode switch?
( Dave may have a better handle on the vacuum build up, but I would think
it's instant or a second or two.)

Hmmm, reminds me that last summer I had starting issues if the car had been
sitting in the hot sun for all day. Never did solve that, it just became
less of an issuel. Is that the fuel accumulator? Could that be working in
tandem or is that my real problem?
( Was this a hot start problem.)If so then you know accumulator and new O
rings in the distributor will normally stop that.)In the hot sun if the
coolant temperature doesn't go down below 95 degrees the TTS switch won't
let the CSV( cold start valve ) fire off when you try to start the car.
Coolant is to hot.) Where as at night and in the morning it may.
