Question type: Maintenance & Repair

Hello my good people,  t would sure be appreciated if someone who
has experienced my problem could help me solve it. I recently bought
a 78 cutlass with a pretty radical 350 rocket in it. I rebuilt the carb and
replaced he starter now when I turn it over it fires and that's it'! No
continuous run. Just fires and quits. Thanks sure would appreciate
some help with this one.
