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.
