Most likley -
A. leaking manifold gasket - check manifold to head bolts are tight, or
B. leads/plugs shot for 3/4

And what's it mean when you accelat\rate it backfires throught the carby and wants to die. Cause i dunno if its not enought fuel or too much, so i dunno if i have to go down in idle jets or up.
Cheers.

that sounds like manifold gasket leak.you will need to remove manifold to check,cant just tighten bolts.otherwiserun car at idle and spray start ya barstard around manifold and if idle increases you have manifold leak
