Honestly, I’d throw the whole lot and replace with a 123-ignition solid state device. It will sort sparks .... forever. Mine runs like a sewing machine after doing this. I was always fiddling with the ignition with the old distributor, I haven’t needed to do this for about 4 years now...
RV8 doesn't like pattern ignition parts - that includes dizzy cap & rotor arm.
Plug leads should be regarded as a service item & changed accordingly.
The rotor arms with the metal strip riveted to the plastic are particularly troublesome & you should use the type with the metal strip moulded in.
Is the inside of your cap clean & dry? The outside also needs to be clean as dirt attracts damp & can lead to tracking - as can dirt on the end of the coil.
On the later electronic dizzys it's possible to disengage the auto advance/retard weights & springs in the bottom of the dizzy by pulling the rotor arm off. These have what looks like an 8 pointed star shaped thing under the arm & this needs to be held down whilst you pull the rotor. A quick test is to turn the rotor arm with your fingers & release. It should go smartly back to its original position.
I'm guessing that yours will be a points type(?) & I don't know if the same applies.
Hold the dizzy end of the coil to dizzy lead a few mm from a good earth & crank. Should be a reasonable spark.
Remove dizzy cap & hold the same lead a few mm above the centre of the rotor arm & crank. There must not be a spark - if there is it's earthing through a defective rotor arm.

As you've got a Lumenition kit fitted you're going to have to try & find Lumenition instructions to check how one of those should be wired as it will be different to the standard wiring & I believe removes & replaces some items. May even be a fault in the Lumenition parts.
If you haven't got a switched 12v to the coil +ve (assuming neg earth system) then you're going to get nothing out of the coil. Early vehicles used ballast resistors & I've no experience of those.
ETA I have no idea whether this is of any use or even relevant to the RV8, found it on a quick google:
