The method I described disables the valves for the cylinders that are
used to pump air, allowing them to pump on each stroke.

Convincing a couple of jugs of any OHV engine to pump air is a fairly
trivial chore for those who know their onions. For everyone else, the
Dunn-Right kit is a very practical option.
