Have a 72 Olds Cutlas Supreme 350 engine with Edelbrock 4 barrell carb.
When the car is cold it starts instantly. After driving for a while and letting it sit. It cranks right over fine but takes a while to start. Smell a lot of gas and acts flooded. Is this a condition of this carb?
Thanks,
Fred

1. start and warm it up to normal temp
2. remove the air cleaner so you can see down the carb
3. shut the car off. If you see fuel pouring down into the intake after the engine has stopped turning it can be a few things.

If it run's fine while hot but starts hard after warmed up with a strong smell of gas. Id say it's heat soaked and the gas is boiling over in the carb bowl into the manifold. Is this a new carb or did the problem just start out of nowhere? If it just started on an old carb it may be just a dirty needle. Other things to check would be float adjustment and the routing of the fuel line try to keep it away from heat as much as possible. If none of that works the carb may be due for a rebuild(if old?) and if that still doesn't fix it a carb spacer can drop temps enough to keep it from happening. or just get a q-jet
