Triumph Scrambles Cub replica - Did raising the carburettor needle bring on difficult starting?

Isn't it strange how you can find something set incorrectly and put it right only to find that somehow you have made things even worse? Here, I discuss an example of such a thing happening today, and my short lived happiness at the discovery of the carb needle being set two notches too low / lean before I tried starting the machine again after putting it 'right'.
