Battery charged?
What does it do when you kick it?

Check the battery & fuses
Then pull the spark plug from the head, plug it back into the cable, lay it on top of the head so it's touching metal, then kick it over and see if you've got a spark jumping the plug gap.
If you have no spark we'll have to figure out if that's due to the coil, condensor, points, etc. If you have spark then it could be that the timing is off or you've got fueling issues.

Yup. Do all of that.
If it's an 81 it probably has a CDI (no points).
