After years of use the carb body will get warn where the shaft has
rotated oh so many thousands of times. The result will be air leaks
around the shafts which makes it impossible to properly adjust the
carbs. I'm assuming the $1600 was for a triple Weber setup which is a
very cool addition but unless you're going to to cams and such is not
really necessary and creates a whole 'nuther ball of worms. As was
suggested, find a nice used set of Zeniths or a shop that can rebuild
yours. Of course, with used carbs you gotta realize that they have
possibly been used as much as yours.<br>

<div> <span>Does anyone on the registry have any experience with
"Throttle shaft bushings" for the Zenith carbs on my BMW? It is
running lean and uneven. The mechanic who has it thinks there are
vacuum leaks associated with worn throttle shaft bushings. He is
telling me to replace with Webbers for only $1600. </span> </div>
