Sure there aint more things to fix first? Tank in line - centred with main needle and make sure no fuel tubes leaks?

When it comes to flip-starting: I always flipstart my engines. I grip around the spinner and flips it backwards without much power. Engines starts easy back the right direction. Sometimes, when overprimed, the engine might start backwards. When this happens, cut fuel, and engine stops. Might need a little priming again.

Flipstarting is simple, when you learn to know your engine, and when everything is tuned and properly put together. Even big 4-stroke can easyli be flipstarted, but dont try to flip it OVER the compression-top (counter clockwise), as the engine might turn back and kick your chickenstick out of your hand.
