you say you have spark, but I haven't seen anything that would lead me to believe it to be sparking at the correct time. Just having the rotor pointing in the general direction of #1 cylinder isn't really adequate. First of all you are using the front cylinder as #1 correct? If you get #1 coming up on the compression stroke, turn the engine clockwise looking at it from the front. Watch the flywheel for the BB and stop exactly on the pointer. Remove the distributor cap, and make sure it is pointing in the general direction of the contact that is leading to #1 cylinder. loosen the flathead screw securing the distributor from turning just enough to allow the distributor to turn, not all sloppy, just enough to let it turn with enough friction to keep it where you let it go. Remove the distributor cap, turn the distributor clockwise till the points open and then close again. Replace the distributor cap. Put a plug in the #1 wire, ground it so it will spark, then turn on the ignition and slowly turn the distributor counter clockwise until you JUST get spark. Turn the ignition off and nail everything down, It should be nearly dead on. If it still doesn't run, it isn't timing.
