Hope it's okay to post here. I've got an 83 SX/4 and the previous owner carbed it so there's no vacuum lines at all. Got the car running but have some kinks to work out.
My question is what is the simplest way to go about this? All other lines were replaced by myself and a friend.
I'm a little lost on what you mean by the previous owner carbed it because the carb you posted pictures of is the same kind of carb that came on these cars from the factory.
These may help you on your search...
