By golly Chuckles that is a nice looking machine! The prop looks like it was routed yesterday.
Your procedure looks identical to the way I go about it (as the assistant) however I always try and start with my left hand and keep the other on the vertical strut. Otherwise I have visions of losing balance and falling into the prop.
Have a mate who was preparing his Midget Mustang for flight after handstarting. After starting he leans over to adjust the throttle, but I found he was lifting his leg to balance himself to within literally an inch of the spinning prop. Sometimes we don't know what can go wrong until someone points it out.
