  1. No more than 30 seconds ✔
  2. No more than 5 minutes
  3. Until the engine starts, however long

Why: Starters are electric motors not built for long use. The AFH says avoid running one more than 30 seconds without a cool-down of at least 30 seconds to 1 minute. Some POHs require a longer cool-down.

Huh, didn't know that: The smell of burning insulation can mean the starter has cranked too long.
