Welcome to the club. It sounds like your car is running rich - and is
essentially flooding out when trying to restart warm. I would guess that your
choke is not operating properly. There is a needle in the choke housing that
has
an O-ring on it. On mine that ring had deteriorated and was letting extra gas
flow by.
This is a common problem with the automatic chokes. There is no rebuild kit and
the manual tells you that it can't be rebuilt. I was lucky enough to run into
a
mechanic that would tell me what to do and had some O-ring on hand.
The common cure seems to be to change to a manual choke or block off the
automatic one. If you block off the automatic one you will have trouble with
cold starts as you don't have the enrichment feature.
Good Luck!
