1 - TDC
2 - One good full length kick.
They are a bit more difficult to kick start when they are cold. That's when I stand next to the bike and do it. (I have done it wearing plakkies before).
When it is warm, it kicks very easy when it is kicked from TDC. I advice wearing boots when kicking with the left foot if you are not used to it.

1- Fuel on and let it fill the carb
2- Two slow kicks right through
3- Fuel off
4- TDC (Yellow mark can be seen through the eye.
5- Kick and hope for the best
6- After the 8th kick if it has not fired up. Then fuel on, fuel off, and kick again.
7- After 30 minutes go have a beer if the bike has not showed any signs of starting.
I see everyone has their method with flooded bikes. I found when a bike floods, close the fuel tap en skop dat die kak wit sit. Sometimes you will find a point of perfect mixture of fuel to air and the bike fires up. Then fuel tap on again.
I have occasionally found that when a bike floods and the fuel tap is left on, it just won't start and the carbs are overflowing. This happens when the floats hook and with you being on the bike you do not see it, therefore, close the fuel tap.
