I know absolutely nothing about Model A carbs so I snapped a couple of photos for you all to peruse. Is this an original Ford Model A carburetor? If not what do you suppose it is? I've been told that the plug in the intake manifold above the carb is where the vacuum line for the windshield wiper motor hooks into. Is it worth the hassle to reconnect the wipers? The wiper arms and vacuum motor are still there but obviously disconnected. Do they actually work worth a hoot? I've been using RainX on my 1948 Ford panel truck for 50 years and don't mind doing the same for the "A". Also did these things not have an air cleaner? That worries me; we live on a dusty gravel road.
