I recently inherited an 82 dodge ram truck. It starts some of the time, but not consistently. I have changed the coil, and I know it's getting gas to the carb. My brother, (who may or may not know what he's talking about) said to check ballest?, and spark plug wires. There appears to be no pattern of when it will and won't start. Any suggestions would be great. Thanks.

 

Ive heard that the ballast resistor can be a problem (should be mounted to the firewall on drivers side) check the wires as well.
