Hy Kato, it sounds like you have no provision for resistor bypass, either in your wiring, or on your igniton switch. Some ignition switches had two ignition positions, usually labelled ign 1, and ign 2, one of them provided 12 volts to the coil for better starting, I can't remember which, I'd have to look at a wiring diagram. The other method was a wire from the solenoid or the small side terminal on the foot switch of a stomp starter, this wire went up to the coil side of the ballast resistor, or to the coil positive terminal itself. If you have a solenoid type starter now there should be a wire going from the small outer terminal [away from the engine block] up to the coil side of the ballast resistor, or to the coil positive terminal. If not then I would install one, and that should fix your starting problem. Incidentally if you want to eliminate your ballast resistors function, simply move all the wires down to the coil terminal on it, hope that helps.
