I installed a HEI in my Stovebolt and use 8 mm plug wires. It is a 12 volt system. It starts immediately and I have been through four sets of Plugs (10mm Champion, AC and NGK. The latest was Iridium by NGK. I have checked everything including the timing. Does any Stove Bolt'er have any suggestions to make to help me solve the Spark Plug life issues?
