Operating a O-360 A3A
Hi,
I just got familiarized with a Robin DR300 that has a Lycoming O-360 A3A (180hp). I have flown O-360s in Cessnas before, but the following two operating techniques as described in the DR 300's POH were new to me:
1) It is advised to use the RPM range between 2,150 and 2,350 only for a short period of time.
2) Starting the engine shall be done on the left magnetos only. Once the engine is running switch to both.
Does anybody have an explanation for those techniques? As for starting the engine, perhaps the 'crank' position of the key (like in off-left-right-both-crank) in those Cessnas I use to fly does use left magnetos only?
Thank you.
