I agree ,one end secured of the spring attached to the case by a screw ,push the shaft with the kickstart rachet on through case and centre of the spring ,with the shaft fully home refit kickstart lever pull assembly back to engage the other end of the spring onto kickstart cog/rachet wind the spring using the kickstart lever and then use the clutch atcivating arm to stop the kickstart unwinding and until you are ready to reinstall.
