engine does not start well

Hi !

I´ve got a 318 in a F-body.

the engine is running well, when it´s running. :eusa_shifty:

but to start the engine, I have ti idle a long time.

:sad7:

I´m using my Volare only for the weekend, so it spends a lot time in the garage.

When I start the car, I´ve got the feeling, it didn´t get gasoline well.

After ideling about a minute or two, it starts and everything is fine.

Where did the gasoline go, when the car is parked ?
What can I do to keep it in the carburator and the fuel lines ?
Has anybody ever had the same problem ?
I have the feeling, it leakes back in the tank. :icon_pale:
What does usualy keep it in the fuel lines ?

Thank You for any Ideas !
