Carb choice for a mutt motor.

Another add-on is a Adiovox cruise control. Before my next drive, I'm going to plug the vacuum port that it pulls from. I have a on-off throttle transition surge that occurs when coasting down hills, and I think that this old CC may have a ruptured cannister. It isn't working at this time so eliminating that is simple. Just wading thru this one piece at a time.
