And this might illustrate all my points.

Later work showed that the PAW would light off first try and keep running if the engine were heated to near running temps with a heat gun.
That's a lot of struggle to get an engine running but WITH ether in the fuel, this PAW will start with the starter, first crack, without the need to play with the compression or main needle.
