Does the lack of elasticity of Haojue Yin Bao -7 throttle cable have anything to do with carburetor?

Yes The lack of elasticity of the throttle cable is usually caused by the stuck throttle pipe or throttle handle, and the stuck throttle or throttle valve and oil needle of the carburetor. Remove the throttle line and check whether it is stuck. If it is stuck, replace the throttle pipeline and add a pull-back auxiliary tension spring at the joint between carburetor and throttle pipeline. Haojue Yin Bao 125-7 originated from Haojue Diamond Leopard Motorcycle. Except that one engine is Suzuki GS engine and the other is Haojue YG2 engine, the other configurations are the same.
