True, the single engine restart checklist has no memory items for the 500, 550 or 560, but the two engine restart checklist does, and it's the same in all three cases:
Emergency restart - two engines:
(starred items are memory items)
*1 - IGNITION - Both ON
*2 - BOOST PUMPS - Both ON
*3 - THROTTLES - Idle
*4 - If alt. allows: AIRSPEED - increase to 200 KIAS
5 - FIREWALL SHUTOFF - check OPEN
6 - ANTI-ICE SWITCHES - all OFF
7 - If no start in 10 secs, either START BUTTON - press momentarily.
(I've left out the notes associated with the cx)
The Bravo cx is slightly different, in that only the first three items are memory items.
