if u flick the ignition on, and get a screwdriver flick the points open and closed and see if they spark
also if u take a plug out, or push a spare plug into one of the ht leads, and put the electrode near an earth point (slam panel for example), then carefully hold it (rubber gloves or pliers advised) see if it sparks while getting someone to turn it over for a few secs
if you have spark at both of these points then that shouldnt be your problem, although checking the points gap would be a good plan to rule it out.
it should be a mechanical driven fuel pump on this model, if so, pull the fuel line off the carb that comes from the pump, careful not to piss fuel everywhere, stick the pipe into an empty bottle n get someone to turn it over for a few secs.
if you are getting fuel then thats sweeeeet.
next question is are the plugs wet? cos if theyre wet then id say it could be something like your timing has come way out therefore not sparking at the right time and not burning the fuel so not firing up.
if the plugs are dry, it could be a problem with the carb.
when u replaced the points and condensor, did u adjust the dizzy at all? is it the type thats bolted via 3x 10mm bolts at the end of the head on the passenger side? also are the leads all on in the correct order?
hopefully that gives u a couple of things to try
