ok, this is a bit embarrassing, but I'm over that.
I pulled the engine / tranny from my 1986 911 seven months ago, tore most of the parts off of it, put it back together and then back in the car. Looking very good, Except, yes, 1 part left over on the bench - a spring. Can anyone identify this part? I've poured over the PET a couple of times and I don't see anything that matches or that jogged my brain.
A couple of hints to go with the pictures.
The spring is what I would call a moderate compression spring, that is, it resists compression (as opposed to an extension spring that will snap something back into place after you stretch it) and it does so moderately - you can compress it between your thumb and forefinger with some force. It reminds me of the oil pressure relief valve springs but not as stiff. BTW, I tore most the engine apart - I had to replace a broken dilivar head stud, so I went down to pulling the cylinders and pistons off of the block, and while apart I disassembled most of the parts to clean and / or replace. It's now back together and running, BUT it does idle very roughly (runs fine at 2000rpm and higher). Does the spring go to the throttle body or air throttle? It also reminds me of the return spring on the throttle body but that is in place and is an extension spring as well. Thoughts??
