While we are discussing how to start it, how about a parallel discussion on how to shut an engine down in an emergency?
I was taught the sequence:
Feather Button - press until it latched in
Mixture - ICO
Throttle - fully shut
Pitch - full coarse
Check prop feathered, feather button tripped out
Firewall shutoff - if needed - pull
Fire bottle - if needed - discharge
The reason given for hitting the feather button first rather than closing throttle/pulling mixtrure was to prevent the prop going the wrong way towards fine pitch and creating even more drag. I think the assumption was that usually even if it's on fire or has thrown a rod, blown a jug etc, it will still be producing some power. A 'dead cut' on an 1830 is most likely fuel mismanagement or fuel pump failure and so would not warrant feathering. In this case we were told to close the throttle and sort it out.
