Sounds like you have an electrical issue to go with your carb issue. Clean and tighten all your battery cable connections. Make sure the starter relay is tight(it grounds through the mounting screws). Check your bulkhead wiring harness for melted connectors. Then check your ammeter in the gauge cluster to make sure the wires are tight. Lastly put a new ballast resistor on it. Keep the old one for a spare if that doesn't help, you'll need a spare since they go out regularly.
