I use the backwards starting "problem" of an overprimed engine to my advantage by flipping the prop backwards and then the engine reverses into the forward direction. Instead of using a chicken stick, I grab the hub of the prop by the spinner and just give it a sharp turn backwards in a position that gives me a running start to the compression stroke. This really works well with four stroke engines and the larger two strokes. Having the throttle closed to idle or a slightly fast idle is critical when starting this way. Not only is starting the engine with the throttle wide open more dangerous, it's also harder to start that way.
