- Material: Plastic construction
- Complete Kit: Includes mounting screw for attachment to carburetor
- Universal Compatibility: Works with Holley 2300, 4150, 4160 carburetors
How It Works
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.
Cam Colors Included
- White
- Blue
- Red
- Orange
- Black
- Green
- Pink
- Brown
Note: Accelerator pump shot relative to cam color from lightest to heaviest are as follows: Black, Pink, White, Red, Green, Orange, Blue, Brown, Yellow
This kit is perfect for fine-tuning your carburetor's accelerator pump to eliminate idle stumble and improve throttle response.
