caprimark

We have a 82 capri with the 4.2 it runs great until you give it some fuel... the only way to get it to rev up is by holding the choke almost closed. This is the problem whether its warm or cold.other wise it stalls out, but will start right back up. This car has set in my sons great grandpa's barn for 14 years and we just got it out to restore it. Any ideas on how to get this thing moving again will help.... Thanks all!
