A couple more requests .
Can you post a close up well lighted picture of the electrode end of the spark plug you have been using .
A picture of the ignition timing ring showing the pickup sensor gap
look on the C&H module for etched letters ,there should be a date and possibly an S or Synch also etched . On your engine with mechanical timing there should NOT be an S or Synch.

You have the correct plug , correct carb. ,adequate battery size .
The prop may be a little too much load untill the engine is running properly but once tuned right and runing correctly the engine should turn a 22x10 around 7000 rpms.
I would put a 22x8 xoar prop on it to get the best out of the engine while tuning.

If you can, post the pictures and we will continue.
