Question 2: How does the throttle work?

• To accelerate, roll the throttle back towards you (fig 1)
• To decelerate, roll the throttle forward (fig 2)
• The throttle is spring-loaded to the idle position (like the gas pedal in your car). If operating above idle and the throttle is released, the throttle immediately returns to the idle position (full forward).

That is all there is for the throttle. On to the clutch in Question 3
