I'm having issues keeping strong spark. I have an industrial truck 218 flathead in my '49 B1B. I replaced the coil, points, condenser, voltage regulator (yes I polarized!) and still no spark. It was running fine, took it to a glass place and when picking it up, would not start. Plenty of battery because it cranks. Thinking of a Petronix conversion but wonder if anyone has any experience to share. Good idea? I'm assuming that the original generator and voltage regulator design work well with the Petronix coil, module and distributor. I plan to leave it 6 V positive ground. Any thoughts, insights before I purchase the conversion? Many thanks! Pilot House Newbie!
