Introduction
This instruction manual provides detailed guidance for the installation, operation, and maintenance of the SPI Choke Lever Kit Dual, Model 05-146-03. Please read this manual thoroughly before installation and use to ensure proper function and safety. Retain this manual for future reference.
Product Overview
The SPI Choke Lever Kit Dual is designed for use in powersports applications, specifically for controlling the choke mechanism on carburetors. This kit provides the necessary components to replace or install a dual choke lever system, facilitating cold starting of engines by enriching the fuel-air mixture.
Safety Information
- Always wear appropriate personal protective equipment (PPE) during installation, including safety glasses and gloves.
- Ensure the engine is off and cooled down before attempting any installation or maintenance.
- Disconnect the battery if working near electrical components.
- Refer to your vehicle's service manual for specific instructions related to choke system access and removal.
- Improper installation can lead to engine malfunction or damage. If unsure, seek professional assistance.
Package Contents
Verify that all components are present and undamaged before proceeding with installation.

- Pivot Pin (1x)
Setup and Installation
Follow these steps for proper assembly and installation of the choke lever kit.
- Preparation: Ensure the area around the carburetor or existing choke lever assembly is clean and free of debris. If replacing an old lever, carefully remove the old components, noting their orientation.
- Assemble the Lever:
- Place the return spring into the designated slot on the lower choke lever base.
- Align the upper choke lever with the lower base, ensuring the spring is correctly seated between the two pieces.
- Insert the pivot pin through the aligned holes of both lever pieces and the spring, securing them together. The pin should fit snugly.
- Install on Vehicle:
- Locate the choke cable attachment point on your carburetor or control panel.
- Connect the choke cable to the assembled choke lever. Ensure the cable moves freely and without binding.
- Mount the choke lever assembly to its intended location on the vehicle. This may involve securing it with screws or clips (not included in this kit, typically reused from original setup or specific to vehicle).
- Test Functionality: After installation, manually operate the choke lever to ensure it moves smoothly through its full range of motion and properly engages and disengages the choke mechanism on the carburetor. Verify that the spring provides adequate return tension.
Operating Instructions
The choke lever is used to assist in starting a cold engine by temporarily enriching the fuel mixture.
- Engaging the Choke: For cold starts, pull the choke lever fully to the "ON" or "CLOSED" position. This restricts airflow into the carburetor, increasing the fuel-to-air ratio.
- Starting the Engine: Start the engine as usual. Once the engine starts and runs smoothly, gradually push the choke lever to the "OFF" or "OPEN" position.
- Disengaging the Choke: It is crucial to fully disengage the choke once the engine is warm enough to run without it. Operating the engine with the choke partially or fully engaged can lead to excessive fuel consumption, fouled spark plugs, and carbon buildup.
Maintenance
Regular inspection and minor maintenance will ensure the longevity and proper function of your choke lever.
- Inspection: Periodically check the lever for signs of wear, cracks, or damage. Ensure the pivot pin is secure and the spring provides adequate tension.
- Cleaning: Keep the lever and its pivot points clean from dirt, dust, and grime. A damp cloth can be used for cleaning. Avoid harsh chemicals that may damage plastic components.
- Lubrication: Apply a small amount of appropriate lubricant (e.g., silicone grease or light oil) to the pivot points of the lever and the choke cable connection annually or as needed to ensure smooth operation.
Troubleshooting
If you encounter issues with your choke lever, consider the following common problems and solutions:
- Choke Lever is Stiff or Hard to Move:
- Check for dirt or corrosion at the pivot points. Clean and lubricate as described in the Maintenance section.
- Inspect the choke cable for kinks, fraying, or corrosion. A damaged cable may need replacement.
- Ensure the choke mechanism on the carburetor itself is not binding.
- Choke Does Not Fully Engage or Disengage:
- Verify that the choke cable is correctly attached to both the lever and the carburetor.
- Check for proper cable tension and adjustment. Refer to your vehicle's service manual for specific adjustment procedures.
- Ensure the return spring is correctly installed and providing sufficient tension.
- Lever Feels Loose or Wobbly:
- Check if the pivot pin is fully seated and not damaged.
- Inspect the plastic components for wear around the pivot holes. If significantly worn, the kit may need replacement.
