I could stretch the copper between my fingers to make it smaller diameter to really dial in the jetting.NO wide bands back then.. just drive it  and jet down until lean surge and then jet up until gone and go another .001 or .002" to be safe.Yea even back then as a teen I was ate up with it.Throttle brackets can get tricky.. especially on old datsun Z cars and old 69 Mercedes 280s with dual 2 barrels.Throttle rotates in a clockwise set up. Funky.</blockquote>
