So just to verify that there were no air leaks I took I squirt bottle and basically hosed down the engine at idle top and bottom of it. No change. Could this happen if there is a crack in the piston? I'm going to tear it down one more time and clean every thing then make sure It's at TDC one more time.
Like I can visibly see a small puff of smoke/steam or something coming from the carb after each back fire if I take the airbox off and run it like that. Which also doesnt show any change.

You cannot run the motor with either the exhaust off or no Air filter on the carb. If nothing on the AIR INTAKE side of the carb you are making it run LEANER than a SKUNK and you will burn that sucker up in no time. Why do you think it is backfiring on you. The only other thing that will cause backfiring besides a LEAN condition is the timing is way off.
