SMJ Carburetor Return Spring (10-pack) SMJ1158

🔧 SMJ carburetor return springs are specially designed to improve carburetor return on internal combustion engines in radio-controlled cars. They allow the carburetor to close more quickly while maintaining smooth and progressive throttle response. They also provide an additional mechanical safety feature in the event of radio interference or a loss of power to the receiver.

• Function: Fast return while maintaining smooth control
• Colors: Black and gray
• Quantity: 10 rubber bands

Important: These rubber bands provide an additional mechanical safety feature and do not replace a properly configured fail-safe system. They must be installed so that the carburetor can return freely to a safe position without interfering with the servo’s operation.
