strange start problems

["K Creason" <dmc4687@xxxx>]

Hey group-
I've got my sticky-idle fixed. I loosened the three throttle spool bolts and
pulled it out to the back and tightened down. Unfortunately it was too much
and I had to twist out the linkage one full turn and then it lined up
properly, returned to full stop and no longer stuck at 1500 rpms. Way cool!
thanks for the advice, one and all.
I also checked my plugs while I was back there. The ceramic was yellowing
and the gap was worn way past the .028". Combine that with cracking the
ceramic while pulling out the first one (just to check it, mind you) and
it's time to replace them all. Thanks John, for the quick shipment. It's
running lots smoother-- I hope my mileage increases too.
But, I've still got a starting issue. The start problem only strikes when
the car has been sitting out in the sun for several hours. It's ok in the
semi-cool garage all night, sometimes ok at lunch, but usually a problem at
the end of the day.
It turns over and coughs and coughs. I do this several times-- trying
feathering the gas pedal, holding halfway down, turning the key all the way
off for a few seconds. Then finally, it will cough and sputter and slowly
get steady and climb up the tachometer to where I can give it gas without
choking it out.
My battery is 3-4 years old, but seems to be ok. I probably should put a
meter on it and check it, just to be sure.
But I keep thinking it's a fuel delivery problem because it really seems to
be related to sitting in the sun for a longer period of time-- like possibly
fuel is being evaporated out of the system and it only starts after building
pressure back up. But I really don't know if that's a plausible scenario or
not.
Help? What to look at and check first?
