Backfiring through Carb

My brothers truck has an Edelbrock 1406 on his 305. If he gets it to start it will run a minute or two then backfire through the carb and die again.

Any ideas would be appreciated
Thanks

Maybe the ignition timing's off or the timing chain jumped a gear tooth.

Timing is definitely off.

Probably too advanced.

Re: Backfiring through Carb

could be timing and cross your fingers it isn't what i'm doing . the cam was bad in my truck it was backfiring and everything. if putting it back in time don't fix it pull valve covers to see if its a whipped cam
