Trivia this week

Typical mags fire the top plugs on one side and bottom plugs on the other side.  I looked at one of the older Jeff Rose EI systems and it is wired this way.   The Fly EFII system specifies top plugs to one coil and bottom plugs to the other coil.     The ignition switch on traditional aircraft have Off/Left/Right/Both.   I'd noticed that some experimental/home built aircraft switches were labeled Top/Bottom.

The cylinder cooling fins have different depths on the left/right sides of the barrel.
