Situation:
Had a toilet that would not flush. Water would slowly drain, but no flushing. Plunged the hell out of the toilet with no success. Replaced entire flush system. Still no luck. Bought a toilet snake a rammed that bitch back and forth for 20 minutes. Still no flush. Finally bought a new bowl (and matching tank). Pulled off the old bowl, poured bucket of water down drain, everything seemes perfect. Even ran a snake down drain to see if it may have been clogged. I didn't even pull up one chunk of ANYTHING. Put new bowl and tank in and everything is perfect.
My question is.. What and how could go wrong inside the bowl itself? I couldn't visually see anything inside the bowl, but that damn thing wouldn't flush.
