Carb Issues

Confused? The manifold has the sheet metal cup with a gasket. What to get the electric or the electric assist. Looks like the one slantsixdan said ( electric conversion) would work fine. Rigged the carb with a small spring holding the choke closed and car start right up. Then once you give it some gas it overcomes the spring and the choke stays open, so sounds like the carb is good just need the choke, just unclear of what one.

Thanks, All
