Compression is between 145 and 150 on all holes. The motor came with an updated ignition which had no spark. I found proper CD Box and coil. Still no spark. I sent my CD boxes and coils, I now have multiples, and distributor away and they work on another motor. Any thoughts?

What ignition system do you have?
Regular auto style with points and condenser, Magna Power II system with points or with a preamp?
Check your groundings for the ignition system.
What is the power voltage to the CD box when you crank the engine?
Need to be at minimum 9,5VDC, preferable 10,5-11,5VDC.
How have you checked the spark on your engine?
Dynamic by cranking the engine over with the starter or static by pulling at the drive belt when top piston is at TDC?
There are different ways to check this battery driven ignition system.

Post a pic of the ignition system.
Try outboardignition.com once you figure out the system.
