just finished rebuilding the carb on my 36 207 and it fire up great then i turned it off so i could put my toe board and floor board back in so i could test drive it and make some adjustments but when i press down on the footstarter there is nothing. no turning over no noise at all. this truck has turned over everytime since ive had it until now. all baterry connections are fine even if they werent it would atleast crank over. anyone know what it is , what finally gave out after all these years?
