Pissed off with motor, want to change

I have to admit I am feeling a small ray of hope due to all the feedback and questions I am getting. Sunday is compression check day. Tomorrow morning pics of dizzy that were asked for and I will try and get a recording of the backfiring to post. It is so sporadic. Can a carb cause this? I have suspected I have carb issues because before this cam I was playing with the secondaries to try to keep it from stuttering on WOT. I would hit it and it would fall on it's face, then stutter and take off.
