Ok guys i just clean out the carb.. and did a car coil conversion on the ignition... the problem here is the engine wont stay running.. it will continue running when the key is turn to the start position.. the starter keep running but not even turning the fly wheel.. which mean the flywheel is spinning by itself... what am i missing.. i connect the ignition switch to the coil position side and the points to the negative with a condenser.. is the coil suppose to stay on and keep providing the spark? do i need to put a resistor in?.. The spark is gone when the startposition is release.. am i missing a wire ? the coil is 12v by the way some say if you have 12v you don't need a resistor..
