If it's that difficult to get to, you may just have to "bite the bullet" and make the repairs. Not sure, but, You may have to disassemble the cowling to get to it. If you're going to get that far into it, you may as well take the broken fitting (probably called a drag-link socket) to your local hardware store and try to match it up to a new one. The biggest problem I can see is not being able to mow in the mean time but that might be better that having to stop frequently to temporarily put things back together.
