I caught myself staring at this car for a few minutes.
Look at how simple everything was back then. For instance, check out the
carburetor and how small and simple it is.
Those gears that you see drive a cable that hooks to the speedometer which
tells you how fast you're going. This is one case where it's not so
simple because a rock could get caught between those gears leaving you
with more than a broken speo.
