Did you disturb the magneto when you had the points and condenser out? Other than a sheared flywheel key that is the only way the ignition timing could be out of whack. Did you remove the cam? If you did, with the head off rotate the flywheel and watch the valves. The exhaust valve will close as the intake opens (valve overlap). This should happen at top dead center, if not the cam needs to be properly timed.

nope but I did loosen the points assembly and had to remove a wire that was under it. plus I don't think I can remove the flywheel nut more than one more time because, when I tried to put the flywheel nut on before and torque it to the proper specs, the nut felt like it was stripping at 40 ft. lbs.

Check the flywheel keyway for a crack which will spread as as the nut is torqued down. I hope it is only the nut that is stripped.

2nd that.
 
Also would not hurt double check torque wrench calibration. I had a couple in the last three years to be out calibration. One would not even click when set at 25 ft lbs until I hit 100 ft lbs. I snapped a couple bolts that was torquing to spec so I pull out the back up wrench. I just replace it when I found it out of calibration.

If the key is sheared it will be obvious and easy to fix. The keyway in the flywheel can be cracked in the corner if it was not properly torqued at some point.
