With the car on level ground and the engine off, climb up behind the wheel. Notice the hand lever on the floor to your left, the two levers on the steering column beneath the steering wheel, and the three pedals on the floor.
Let’s start with the hand lever. All the way back it sets the rear wheel parking/emergency brakes and puts the transmission in neutral. Half-way released it maintains neutral, and fully released it engages the planetary transmission in high gear. Feel it a few times, notice that it holds the left pedal in neutral mid-position, then release it, and notice that the left pedal is all the way up.
Next, the lever to the left beneath the steering wheel is the spark adjust advance/retard from before top dead center ignition to after top dead center. To retard the spark it is moved up, to advance the spark it is moved down. The Model T is always started in the retard position, as it was designed to be started by hand cranking. Unless it is retarded the engine can and will KICK BACK and do damage to hands, wrists and arms. NEVER crank it except in the retard position. After the engine is running, the lever can be moved down to advance the ignition until the engine chuckles smoothly, and when rolling to get the best performance.
