I start them in this order - Engine #3, #4, #2 and #1

After Start
Essential Power Source Selector.......................................GEN 3

And for push back, I do the same as nath2889.

Hi Remy.

It is not included in the After Start Checklist because it's in the Before Takeoff Checklist. I don't think it could hurt to turn it off after starting the engines though.

From the ‘707 Captain’ FLIGHT MANUAL Part III – Normal Procedures, page 27:

AMPLIFIED BEFORE TAKEOFF CHECKLIST
After leaving the gate and prior to taking the runway, the Captain will call for the Before Takeoff Checklist.
The Flight Engineer will read aloud each challenge and receive the appropriate response from the designated
crew member.
