Did you line the dots up on the timing chain?
If the dots align, then.
I would say you are 180 out, I did the same mistake when I was 16 and changed my first cam.

Pull #1 spark plug, have a friend "bump" the starter.
Place your finger over where the plug was.
When you feel a big rush of air, point the rotor button towards #1 wire.
Fire it up and adjust the timing.
