Sorry I called you skip earlier, just missed your name at the end of your post. That further clarification helps, too.

One of the websites I looked at while trying to unravel all this implied that diesel engines are simpler than gasoline engines because they don"t require an ignition system. Not sure I"d subscribe to that theory - seems to me like the added complexity of the diesel fuel-injection system (and the varieties thereof) might counterbalance the simplicity of no ignition system.
