I have an 82 rabbit and its running very rich and i have no idea on where to even start on fixing it
Perhaps a used Service Manual frome ebay or Amazon? Quick check and people are asking crazy prices... I guess I'd wonder if the fuel pressure regulator was acting up, or maybe the weakend ignition wasn't burning fuel all the way. Back 40 years ago we'd take Cadillac alternators and put them on our trucks because they had so much more charging amps than any other models around. As for CCA, I've been using the largest battery that fits in the battery box of my cars. The alternator has been keeping them all the way up. The CCA may vary between different manufacturers for the same specific application.
Air box has a small hole in it dead center beside fuel system i believe 7 allen key fits it turn up or down to lean out mixture. and alternator should not really matter on the year no computers or bs to fry. I own a track and a road 83 gti.
