I have an older 90's murray riding mower. I bought a new gear sector assembly. I have a spring that has to be put back on it. It didn't come in the new assembly. I don't know how to reinstall the tension spring and the diagram in the manual is not clear. It is the spring that puts tension to the arm that engages the deck. There is a lever on the gear assembly that moves and the spring goes there. Can anyone show me a picture of how its put on or tell me how to fix it.
