It’s got smoother acceleration now that I replaced the vacuum advance can on the distributor.

I still have the stock carb on but I do have a weber swap kit in the garage ready to go. It’s running pretty good with the stock carb though so I’ll hold off on the weber for now.

Question.... Is the stock carb a two barrel with vacuum secondary or mechanical secondary?

 

Remember the Weber tips when you do install. Sand the adapter plates perfectly flat, use Permatex Aviation on the gaskets, and torque properly.
