The rule for changing "up," that is from a low gear to a higher gear, is--Declutch, place the gear lever in neutral, pause a short time, place the gear lever in the new gear position, re-engage the clutch, If a "clutch-stop" is t- ted, and is known to operate satis

be faeterlly, the ,pause may shortened or omitted ultogether. The function of a clutch-stop,. which usually takes the form of a pad rubbing against the rear of the clutch (e. agafust a portion of the clutchshaft), is to check the spinning of the clutchshaft under its own momentum when the clutch is withdrawn. When one is fitted it comes into action only when the elutch pedal is pressed down to its fullest extent, and If no atop is fitted a pause in "neutral" has the same effect.

For changing "down," that is from a high gear to a lower gour, the rule is--Declutch, place the gear lever in neutral, re-ungago the clutch, speed up the engine by rinnaling the throttle pedal, again, declutal, immediately place | the car lever in the now, genr) position, re-engage clutch.
