Always start at the beggining, and check all the tune up settings:
-Adjust the valves (If they're way off, they could cause this.
-check all vacuum lines and other hoses. Replace if cracking.
-Replace fuel filter
-clean the carb- preferably, remove it, check the float, and any rubber parts.
-check the points, rotor, dist cap, wires, igniton timing, etc.
-do a compression test.
-etc.
Then see how it works
- Loss of power, and backfiring through the carb may indicate bad ignition or
valve timing, bad valves (or adjustments)
-it may also indicate a lean condition- lack of fuel (Float, or filters,
etc.), leaking vacuum lines, leaking gaskets, etc.
- Another possibility is a plugged exhaust or catalytic converter.
