Boy does that sound familiar! When I bought my '47 Dodge (6 volt, positive ground) the owner told me it needed a valve job. It ran like crap.
Same story as yours. The battery was in backwards and the coil had not been switched. I switched the battery terminals, polarized the generator, gave it a good tune-up and a new coil connected properly, and it ran great for years.
