Jed, Sure a weak coil can cause all sorts of ignition problems, but thats not my first suspect for now at least. If you run Autolite plugs try the NON RESISTOR 3116 or if Champion try a hotter plug also. Use wire core plug wires NOT carbon core resistor suppression wires. Dont run the carb any richer then necessary i.e. lean it for light duty use and richen it up only enough to do the job under heavy loads. If shes black smoking any excess out the stack run the carb leaner and insure the air filter n inlet piping is all clean n free. Other then that the points n condensor n wires as you mentioned and HOTTER plugs may help PLUSSSSSSSS use radiator air restrictions or shutters or thermostat etc TO GET N KEEP THE ENGINE TEMPERATURE UP can help also. Its not all that expensive to try a new coil if the spark is a faint yellow as compared to the desired visible BLUE and all else is okay. John T
