Cold Starting Difficulty. CV.

If I just pull out the enricher without a few priming twists it will never start.  I'm in Ireland so temperatures average around 53f although this weekend we are in the middle of a "heatwave". It's 64f!
It goes really well once it's warm. However sometimes if you crack the throttle it will cough before picking up. I'll need to keep at it but it's 95% there. Would a #45 jet help? I've got one but I don't want to "Potty mouth"k it up. It's not Smokey or smelling of unburnt fuel.

A 45 won't hurt at all, and is usually the first mod to do to the carb, after drilling out the cap and adjusting the idle mixture screw.
I would still remove the enrichener and clean that circuit, check the o-ring.
