Ok i think I found one of my problems. Just found tuning directions from super tigre. Tell me to open carb 2 1/2-3 turns to start tuning the carb. I was starting 1 1/2 turns out. Would explain why it was stalling out at full throttle. The engine was being starved for fuel. I'm going to seal everything up and tune this thing according to the directions, to the letter.
