CU20-12

Each cam has a different shape or profile to give different results. Cam "lift" directly affects the accelerator pump stroke and, therefore, pump capacity. Ramp profile or shape controls the "timing" of the shot. A steeply rising ramp shape will give a fast, heavy fuel shot right off idle. Conversely, a gently sloping ramp will spread the pump action over a longer period of time.
