This may sound pedantic, but did you observe that the car
was running cooler by other factors other than the gauge?
Depending on the layout of the cooling system, sometimes changes
can affect what the gauge reads without really affecting the
running temperature.
I forgot what year your midget was, so I don't know the layout.

This will happen if a valve sticks, such as from
major overheating causing the tolerances to change.
The valve opens and stays down because it sticks
in the guide, so when the cam lobe lets the pushrod
down, it falls out of "ball" on the rocker arm
and then it's free to fly.
