One problem is that the tach on the Tach/Dwell meter reads differently than my Autometer inside the car. They have about a 100 RPM difference! So this is obviously going make a difference when timing the car. I decided to use the Autometer to set the idle at 750 but since the other meter is off, the dwell reading is probably not right either. O well! Will go electronic sooner or later. Thanks for the help guys!
