Just to add one thing if you are using the choke, don't be tempted to turn the throttle at all. Even lifting the throttle valves a little will render the choke circuit useless.

I see.. How to tell if they are resistor caps?

There's an R in the name - mostly.

Just don't fit resistor plugs AND resistor caps if you have electronic ignition.
One or t'other.
Neither if you are on points.

I know that the plugs have an R in the part number if they are resistor types, but how do I tell if the plug caps have resistors?

OK - turns out I had resistors in the plugs AND the caps... New set of B8ES plugs fitted now, and there's a noticeable improvement in throttle response. Time will tell if it helps the warm starting, but I think it will!
Next question - the restorer has re-inserted the original white rubber damper bungs between some of the cylinder fins. They are a bit "off white" and there's not enough of them.
Can I just take them out, or do they actually reduce resonance and ringing of the fins?
If I do need them, where to get them?
