Sounds to me like you have the cam tooth retarded one or two.  Find <0> on the
flywheel, then take a look at the camshaft mark.  It should lie in line with
the cam cover (below the equalizing bracket).  Remember, if you change the
belt, you will need to change the dist as well.

Lifters tend to click on idle, and it goes away as the car heats up.  If
lifters are causing the problem between 2-3k, you should have a racket at

If the timing is correct, start looking for obvious vacuum leaks.

Ck the timing again.
