Are you certain that you have the plugs connected up on the right order? 

I've connected up plugs the wrong way on the MX5 MK1 we had and it ran, albeit badly. Likewise on the MGB too. 

No, but I haven't changed the order since I got it. They are 1342 in an anti clockwise direction, as far as I remember

Just went and finished replacing all the vacuum hoses. It was sitting idling badly as per usual, so started disconnecting the HT leads one at a time. All caused the engine to stall, except for number 2, where the car kept idling. I held the cable near the engine and although there was a spark, it was weaker than the rest. 

They are brand new leads though.

As suggested try a selection of the old leads in place of number 2.

Does the inside of the cap look correct and not damaged?

Compression on the cylinder should not make any difference to the spark so if it looks less than the others then that should be you issue or at least one of them.

Only potential issue is the rotor arm, which has not arrived yet. 

 

As a side point, I had a similar issue with a Lada I had, ended up changing the engine. 

Only when dismantling the old engine did we notice that the distributor shaft was bent. ?‍♂️

In other news - compression test report. 

As long as I'm doing it right?

Turning the engine with the other 3 plugs in, but all leads disconnected.

Gauge jumps to 125ish, and on further cranking clicks up to about 185-190. 

Sound about right? It does the same for all 4 cylinders.
