Here's a pic of the tool(s) I made. I just used a 4" CI to PVC adapter and put a piece of laminate with a hole in it in the groove. It fits perfectly over the Zenith and you can even tighten it up if you want to. You should make two of them and just move the Unisyn from one carb to the other. It is really critical that the timing is right on and the bench adjustments are right. I have found that most of these carbs are really screwed up by people who don't umderstand them.
