Hi Robert,
That is absolutely correct !
I must just add, that at one time a lot of Army equipment was fitted with a Start Pilot device which accepted a small metal cartridge, once loaded, the plunger was pushed down this punctured it and pumped the ether into the manifold. All the Bedford MK's had it on the dashboard, never, ever had to use it. But the one that really brought it home as to how dangerous it was to an engine, was the little Petter diesels used on pumps and generators, cannot remember whether they were AA1 model, anyway, came across one in for repair with no compression. It had an empty cartridge in the pump, and found that it had stretched the cylinder barrel studs. Bet it kicked on the starting handle too !
