O8K, just typed a response, but won’t repeat my expletives about this website…

Does the engine actually run, or just backfire when you attempt to start it?  The engine will not run if the timing is off 180 degrees.  So, if the engine runs, and you suspect a timing issue, perhaps you did not torque the flywheel nut properly and the key has sheared knocking the timing way off.

Hopefully you can post a video which will help give us a better idea of what is going on.
