John, yes that is a nice animation… Unfortunately it isn’t an Oil Head that is an Air Head..


Still a nice animation just wanted to make sure it wasn’t confused with what the current Oil Head uses..

This is very good. Note the cam shaft inside the block and pushrods, this is the air head design. It will make a nice screen saver! Thanks!

Nice graphics :)

Now, I was not aware of that "wasted spark" thing, as indeed represented on the graphics... Would someone please explain?

Wasted spark means both cylinders spark whenever approaching TDC. The spark on the compression stroke is useful.

The spark on the exhaust stroke is wasted.

But why??? Is it because it is simpler to get both to spark at the same time (common wiring)?

Yes, simpler/cheaper. No real downside except for a little additional wear on the plugs.
