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

yES THANK YOU dAVE, I WOULD MOST CERTAINLY GET IT ON A DYNO AND GET IT GAS ANALYSED, I AM RUNNING A 2 1/2" INCH BUT WOULD CERTAINLY START BY CHECKING ALL THE TIMING THINGS ....

i had the same problem with an a14

i'd like to know how it works out for you ...

I will let you know after the weekend!!!!!!!!!!!

Check that the mechanical advance is working in the distributor.

Oh yeah man I have been there!
I have an A15 with a 240 degree cam competition valve springs, datrats dizzy, big ports, extractors and 2 1/2" exhaust and a weber 38/38 DGAS downdraught carburettor. I had a problem where it would hit about 5500rpm and start coughing and spluttering pretty badly and wouldn't rev any more, after a couple of weeks or testing new parts, trying different jets, spark plug gaps and timing settings it all came down to two things.
1) I fitted a new fuel filter and when I disconnected the filter-to-pump line I noticed quite alot of air bubbles escaping from the filter outlet before any fuel came pouring out. I think I had air cavitating in my fuel pump causing incosistent flow into the carburettor bowl.
2) I put a new set of NGKBP5ES plugs in and left them gapped at .033" which is the stock gap, previously i had tried running .044" gap because thats what the datrats dizzys are capable of

Thanx all ill give al your advise a shoot and see maybee i am lucky,
