I take it it is not a CVH engine orion then!!
I assume therefore it is a mk3 ?, with the zetec, these do indeed come with a spring which is about as much use as a limpy on a date with Cheryl Crowe!!
Just chuck the spring, tension manually, it's quiet dangerous to fit the spring as so loose it could come detached and does jack all anyway.
Had this on early zetecs before, just ensure peg goes into recess it will be fine, tension as normal and lock off.
