How much should the clutch be released for starting on a slope in Subject 2?

[DelHenry]

On the basis of semi-engagement, release the clutch a bit more to make the vehicle shake more violently, then slowly release the brake to avoid stalling during start. Alternatively, on the basis of semi-engagement, add a little throttle. Usually, the starting speed is around 900 rpm, close to idle speed. You can increase the throttle to raise the speed to 1000 rpm, let the car move, and then release the clutch, which can also prevent stalling. The reasons for stalling when starting on a slope are as follows: 1. The clutch contact point is not lifted enough (the clutch is lifted too low). 2. The handbrake is released without giving throttle (the car's idle speed is too low to start the vehicle), causing the car to roll back. 3. After rolling back, hastily braking or lifting the clutch causes stalling. 4. When starting, the clutch is lifted past the contact point and the handbrake is released too late, causing stalling.
