David- if you have power at the points, and the engine block ground path is good, there're only two things left that'll prevent you from having spark at the plug:
1) ignition coil bad
2) contact points aren't opening and closing
Remove the point cover, turn the engine 'till the points are closed, Remove plug, ground it firmly to the block, turn on ignition, and open points by hand- a chopstick works well for this. If the points open, and no spark, coil is bad. MAKE SURE, however, that the points actually closed, and ignore what the service manual says about point-gap- that measurement is only valid if the engine is new, and there's no camshaft point-lobe wear. The proper way is to set the contact points to begin opening when the "S" mark passes by the flywheel timing-mark inspection window (in the flywheel shroud). The timing mark is usually NEXT_TO_IMPOSSIBLE to see, so plan on having a good flashlight and a 5-gallon bucket to sit on while you hand turn the flywheel a little-at-a-time. Best way is to find the compression point, and look around from there (timing mark isn't at bottom-dead-center, obviously).
If it ran yesterday, and no parts or oil came out, it'll run tomorrow too.
Did you, perchance, clean the contacts of those points before you put 'em in? If not, do- they come coated with some kind'a crud that's a better dielectric than conductor... usually takes an alcohol swap to clean 'em to good working-order.
So far, you're not impressed, but with wide-frames, you will be, and there's not a darned thing you can do about it!
