Matt... the first thing I would do to get spark is to make sure the spark plug cap is not loose or broken.
By the way... where did your coil and wire and cap come from?... I remember you were going to substitute one from something else...that could be a problem.
If they are good... then I would first clean the points... because if there is ANY dirt.. even a speck... you will have no spark.
As far as starting...The PA50 has a cable operated compression release mechanism built into the cylinder head.. if it is leaking your ped will not start.
I have removed the pedals on mine and push start it with the release pulled in.. I have to push it about 5 feet...then release the comp. release lever.
