It's starting to sound like non California cars may not have what I've been referring to as a check engine light. My car was a California car from new. The best ground on any car is the negative battery post. The smell is very possibly the new cat, and the droning noise may be having to do with the cat as well. You may want to check and see if the cat is touching the heat shield that normally is between the cat and the floor of the car. Until you get the basic timing sorted out, I wouldn't worry about the cold start issue. There is a cold start valve which is mounted to the intake manifold, on the tranny end of the manifold. But if the car only takes a couple of tries to fire when fully cold, the valve is probably working. Sounds like you're on the home stretch, just double check the Bentley for the exact basic timing procedure. You could try and get the car smogged, just find a place that promises free retests if you fail. Most smog stations in California do. Hang in there, you've come a long way since your original post.
