Hi Photoboy, 
The starting procedure i used for my rev3 was: 
1 open fuel tap 
2 open choke (only required on cold days, would often start without) 
3 throttle closed (i think that full throttle shuts of the fuel completely - but i could be wrong) 
4 find compression on lever, kick hard as possible / repeat - giving small blip on throttle until it fires 
5 blip for couple of seconds and shut the choke (if used). 
6 then ride... 
If that doesn't work i would whip the carb off and give it a good clean. 
Good luck.
