This is unfortunately the case. Here's my recommendation, buy two of the exact same vacuum secondary carburetor, one nice and new from Summit or Jegs and the other a cheaply priced used version off of Ebay. Then watch YouTube videos on taking it apart, cleaning and adjusting it, how to change jets, power valves, how to adjust the A/F ratio, how to get it to idle off the secondaries instead of the primaries, the importance of the transfer slot, vacuum and so on and so on. Do all of that as you practice on the used one there at your kitchen table until you start to feel pretty good about your skills when it comes to monkeying with it at the table and then have one of the old guys at your local club show you how he likes to tune and adjust your carb. If you lived across the street from me I could have you up to speed on tuning your Holley is one summer and the knowledge will last you a lifetime. A properly tuned Holley is an absolute joy to drive in a Cobra whether you're driving hard or just puttering over to the car show.
