The automatic didn't have a throttle control. It was controlled by the front and rear flap. Of which there was a cable connected to the front and rear flap. So you had a cable coming from both. They both connected to the carby. So both cables went into that brass fitting. That's why there's two holes there. It was surpose to rev the engine as the flaps went over higher grass and less for lower grass. The theory was good but apperantly this failed and that's why the project was scrapped. Most automatics were then converted back to the throttle type like your has.Hems making them rare and very collectible with all the gear still on them. As not all were converted. There was only 10,000 full automatics produced. How many are left who knows.
