Car is a '69 E-Type with dual Strombergs. The top (dash pot) is held on by 4 screws. I noticed a while back that one of the 4 screws is longer than the other three on both of the carbs. I was talking to a parts guy at one of the Jag parts distributors and asked him about that. He said that he vaguely remembered once at a show seeing this and that the longer screw had a hole drilled in it. He recalls that there was a wire going thru the hole with a small piece of lead crimped on it. He doesn't remember what the crimped lead looks like and has no idea what it was for. Does this ring a bell with anyone?

Just curious,
