Good questions! I was puzzled because the edge is ragged so it looks
more like a break, metal fatigue or something. Also, I don't have an
air pump (mine's an early '74, March) and it generally runs rich
anyway. The car has approx. 112,000 miles on it.

If the missing bit is small and smooth-edged, or rather the hole where the
bit was, then it sounds like a burnt valve. This could happen if you did
any high speed runs under lean conditions. You don't say how many miles are
on the engine. Does your car have an air pump? This made engines run lean
to lower HC emissions. Just a thought.
