It was somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember The Natural Philosopher
saying something like:

Oh. Best way to start old diesel tractors is to pur fresh diesl in on
the glo plug and let it burn....

An old diesel Landy I had the unfortunate privilege of using
occasionally would only start with a burning diesel-soaked rag held next
to the air intake. Crude but effective.
