Hand propping mt propeller
Lycoming, Continental, Hartzell, McCauley, or any broad spectrum drive system component used on multiple type.
Im sitting here waiting patiently for my maule to preheat and got to thinking about getting in a situation where it needs hand propped. Im curious because they start awful fast. It just a two blade but still...
Thoughts?

Never understood why we don't put a nice pulley right behind the spinner.

Half a century spent proving “it is better to be thought a fool than to open your mouth and remove all doubt.”
I’ve hand propped Huskys with O-360 Lycomings with MT props a few times. It’s no big deal. Be sure the prop is installed with blades at 10 and 4 o’clock, viewed from the front. And I almost always prop from behind the propeller.

I’ve seen a pponk’d 180 with a 3 blade MT get hand propped. I was uncomfortable just watching! They did a good job getting it started though.

I hand prop my 55 C170B with a 3-blade MT prop on a Lyc O-360. Every other blade will line up with compression where you want it. I rotate to that position, turn mags hot and pull from the front with a person at the control who knows how to run the engine when it starts or if something goes wrong. I always prime , then pull thru at least 4 compression strokes before every start anyway..always treat prop moving in normal direction as if it will fire during the compression stroke. Chock tires, keep throttle back, have someone at the controls adn turn the engine off with mags to insure they really are not hot when you think they are off. Do be careful of large bulky rings and wrapping your hand too far over the trailing edge of the blades as when you pull through, the ring will try to chip the surface of the trailing edge...first knuckle only for safety also.

Shouldn’t be any different than a Cub with a wood prop.
IOW, like a light switch.
