I got this flyer along with a spring that I ordered from Daytona Parts Co. (Carburetor).
I wanted to post this -- but PLEASE don't shoot the messenger. I don't know exactly what to make of it, and offer it for discussion.
"Daytona Parts offers new high quality "Metallic Core" spark plug wire sets for all pre-1970 vehicles.
These wires were made to operate and deliver correct voltages to the spark plugs thru low-resistance metallic solid core wires.
If you operate your pre-1970 vehicle with newer HEI supression RFI wires (Bart note: the ones that look like carbon core), you are causing low voltage to the spark plugs, which may result in hard starting, poor gas mileage, decreased performance, rich running, fouled plugs, and other symptoms that seem carburetor related.
All american ignition systems from 1974 and up, use HEI (High Energy Ignition) with output of 35,000 to 45,000 Volts. Your original point sytem runs in the 20,000 Volt range, and will not be able to provide the necessary voltage through modern HEI wires."
