I recently installed a rebuilt pair of strombergs on my car. I took extreme care to get the float level correct and to avoid any vacuum leaks. The metering needles were brand new. The mixture was too lean;no matter what I did. The throttle shafts were new too. I had to install the old needles to get the proper mix. On visual inspection the old and new needles appear different. The new needles are longer and seem a little thicker at the base. That would make it lean at idle. Has anyone else had a similar experience? The worn needle would give richer mix. I had the new needles adjusted fully clock-wise and still too lean. I got the new needles from two of our common sources.
