If the plugs don't fire when the engine is turned over, but you do get spark when manually opening the points with a screwdriver, there are 2 possible problems. Either the timer cam is not opening the points or the points are not making contact and you bridged across them with our screwdriver just before opening them. Disconnect the points wire at the coil and turn the engine over 'til the points are closed. 'Flash' the points wire on the coil terminal with the switch on to make sure the points are grounding the wire. Next, turn the engine to get a cam lobe under the points rubbing block and repeat the test to make sure the wire is no longer grounded.
One more thing to check if the wire stays grounded is the condition of the rubbing block. If the moving contact is touching the cam because the rubbing block is worn, it will behave just as you described.
