I think that choke and tickler is overkill unless it is a very cold day. Since I also use a grossset starter Danno could try doing it the way I do on my shadow ie: apply full choke on both cylinders, press starter button with throttle closed and bike should fire right up....too simple? There is of course one important differece between my shadow and danno's bike...I have a BTH and he has lucas rita. Both systems will produce a good sprk at low RPM BUT the lucas rita relies on the battery and needs a decent voltage to work properly so using the starter may be affecting the ignition system. My mark 3 commando has this issue if the battery is a bit low (usually when the bike has not been used for a bit)... the starter will turn the engine over but it doesn't fire up, kick it and it starts right up. food for thought.
