If you set the points to open when at TDC and fully retarded that should be close enough for it to run. You can check the spark by disconnecting the plug caps from the lead, leave the plugs in and hold the end of the plug lead about 1/4" from the spark plug cap. Kick the bike over and see if you have a spark. If you have tried spraying easy start in the carby and it didnt do anything then you have something wrong, it should at least fire a few times. Have you checked that you have the correct plug lead going to the correct cylinder? To do a simple check take both plugs out, hold you finger over one plug hole and turn the motor over until you feel pressure against your finger, then bring that piston up to TDC, you should have this cylinder on its firing stroke at this stage. Once you have done this follow the plug lead from this cyl back to the maggy, remove the pick up from the maggy and look in the hole [may have to use a mirror] you should be able to see the brass strip on the pick up ring. If there is no brass strip visible swap the plug leads over. Hope this helps, Brian.
