My 1975 VW Rabbit came home rejuvenated from the shop today. (As I wrote in an earlier post, restoring my 33-year-old Rabbit, which has been in my family since it was new, is the method I’ve chosen for achieving better gas mileage). Its main problem was that it had about a half-inch of rusty sludge in the bottom of the gas tank. This (and the underlying problem of water finding its way into the gas tank) had caused a variety of problems. The good people at the Independent Auto Werks in Corvallis cleaned the tank, blew out the fuel lines, did a partial rebuild of the carburetor (including replacing a clogged idle jet — no wonder it didn’t want to run!), and now the car is running better than it has in years, maybe decades.
