   I'm glad I changed the plugs and I don't recall whether I needed to or not,   
   but my first reaction upon seeing them is that the previous owner must have   
   done all of their driving in the city.  So, since I was changing the wires, I   
   decided to save myself some time and change those, too.

   So it would seem.  I rember at a Rochester carburator class back in the   
   Fifties being taught that if you didn't give the engine the gas supply going   
   uphill that it needed, the mixture would be rich and you'd sooner than later   
   be reachng for a can of top engine cleaner.

   I had a 1977 Monte Carlo.  It was the last brand new car I bought and it was a   
   pleasure to drive.  I remember turning down $10k for it in 1990, but I don't   
   regret doing that.  The one thing I do regret is being told by the warranty   
   "genius" from GM, when I was told that the car had a "right lean" to it, which   
   meant it pulls slightly to the right and they wouldn't fix it under warranty   
   -- nor could they, probably, to get on the highway, he said, get up to 80MPH   
   and slam on the brakes.  I never spoke to him again.   
      
      
   Regards,
