One additional detail…
Even if using 35% throttle position to start a 912iS, the RPM will always exceed 2000-2200. Sometimes it will even exceed the alternator switchover RPM of 2600. Rotax expects this to happen and specifically specifies it for a few seconds to activate the switchover. You are THEN supposed to retard the throttle to keep RPM below 2500 until oil temp reaches 120 F.
