My best friend's first car was a 1978 Rabbit. About fifteen years ago it started running rich. I put the gauge on it, control pressure equaled system pressure. Screws were so rusted I couldn't even take the warm-up regulator apart to try to free it up. I gave him a 3mm x 9" T-handle hex wrench and he was able to keep driving it for another year by adjusting the mixture to the weather. Then he bought a Grand Am and sold the bunny to a broke college student.
