Don't know about s3, but the s2 dizzy #1 lead pointed at #1 cylinder
Sure you don't mean the rotor arm points to the number one lead/contact?
I have worked on cars where when you fit the dizzy, the rotor turns as the shaft enters into mesh. Don't know the series motors at all, so don't know if the drive is with a dog or a pinion type thing,
If I was in any doubt, I'd switch the ignition on, turn the crank to the firing point presumably TDC, ensuring number one cylinder was under compression, check the rotor arm is pointing towards the #1 lead in the cap, then, with the cap off, loosen the locking device on the dizzy, advance it, then retard it until I can see/hear the spark.
Once locked up, this should then mean it would start even if the timing would need adjusting.
@Gun7354 , are you getting a spark at the number one plug at any point on the cycle? The problem could also be any of:
wrong gap at the points,
dodgy rotor arm
dodgy condenser,
dodgy coil
dodgy connections to any of the above, especially the cap, for instance you could have accidentally earthed the points
or fuelling problem.
Best of luck
