The adapter from Toni Clark should have a pulse hole in it to line up with the hole in the carb base...Be sure ypu put the carb on the engine the right way...The 62 pictured has one of my older mechanical advnace units on it, you can just see the 4-40 rod on the front behind the hub...New versions have a different hub without the 4-40 rod...The carb on this one already had a pulse port fitting in the carb backplate so there's a neoprene line from the side of the case to the back of the carb...
