The Weber 32 36 is a popular carburetor among car enthusiasts due to its performance capabilities. It is a two-barrel carburetor that can be found on a variety of vehicles, including the Toyota Corolla, Ford Pinto, and Jeep CJ7. One of the most important aspects of tuning a Weber 32 36 is adjusting the screws. In this article, we will discuss the Weber 32 36 adjustment screws and how they affect the carburetor's performance.
Main Adjustment Screws
The two main adjustment screws on a Weber 32 36 are the idle speed screw and the mixture screw. The idle speed screw is located on the side of the carburetor and is used to adjust the idle speed of the engine. The mixture screw is located on the bottom of the carburetor and is used to adjust the air/fuel mixture at idle.
When adjusting the idle speed screw, you want to set the idle speed to the manufacturer's specifications. This is typically around 800-900 RPM. To adjust the idle speed, turn the screw clockwise to increase the idle speed and counterclockwise to decrease the idle speed. Make small adjustments and wait a few seconds for the idle speed to stabilize before making another adjustment.
The mixture screw is used to adjust the air/fuel mixture at idle. To adjust the mixture, you will need to use a vacuum gauge or an emissions analyzer to ensure that the mixture is within the manufacturer's specifications. To adjust the mixture, turn the screw clockwise to lean the mixture and counterclockwise to richen the mixture.
Secondary Screws
The secondary screws on a Weber 32 36 are the accelerator pump adjustment screw and the choke adjustment screw. The accelerator pump adjustment screw is located on the side of the carburetor and is used to adjust the timing of the accelerator pump. The choke adjustment screw is located on the choke housing and is used to adjust the choke's opening and closing speed.
The accelerator pump adjustment screw is used to adjust the timing of the accelerator pump. This screw controls the amount of fuel that is delivered when you step on the gas pedal. To adjust the timing, you will need to use a timing light and adjust the screw until the timing is within the manufacturer's specifications.
The choke adjustment screw is used to adjust the choke's opening and closing speed. To adjust the choke, turn the screw clockwise to increase the opening and closing speed and counterclockwise to decrease the opening and closing speed.
Conclusion
Overall, the Weber 32 36 adjustment screws play a crucial role in the performance of the carburetor. Proper adjustment of these screws can lead to better fuel economy, increased horsepower, and smoother idle. It is essential to follow the manufacturer's specifications when adjusting these screws to achieve optimal performance. If you are unsure about how to adjust the screws, it is best to consult with a professional mechanic or carburetor specialist.
