Sakkie,
Unless your fuel pump is sick it won't be that, nor will it be points ( assuming that they are ok ). My A14 with twin 40's runs the standard fuel pump and to be perfectly honest apart for starting I certainly haven't exactly noticed a 'quantum leap' by going to an electronic dist.
I would suggest that you start with checking both your cam and ignition timing.
What sort of exhaust are you running?- It will need to breath and certainly check that you are indeed getting full butterfly opening at full throttle.
The dyno ( or a portable gas analyser ) is a very good idea too- who knows how far out your carbs are.
Start with the basics first b4 you start wildly firing money at it.By the sound of your setup 7-7500 should be easily achievable.

Hope that this helps.
Dave
