'65 idling question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Changed the plugs/wires recently the '65. Ran fine for a while but now has been idling rough and cutting out. But, when I set the choke it runs then chokes itself out after about 1-2 minutes unless I feed it.

Thinking vacuum problem? Plugs were set right and wires double checked. Not thinking fuel pump (mechanical) since it is getting fuel?

Running a 350 with rebuilt heads, RV cam, 4 bbl edlebrock and an HEI distributor.

Am I on the right track?
