Picked up a used 750 Mighty Demon... where to start?

Well got the leaks fixed, ran the carb first last night on the primaries then hooked up the secondaries today... it runs PERFECT!!! No stumbling, surging, flat spots anything like that it just throws you back in your seat when you stomp on the pedal. Just from the way it feels I'm sure I picked up at least 25 HP and probably the same in torque I'm super impressed with this carb. I was expecting it to behave like it was too much for the engine but nope! It even idles smoother than my Carter did which surprised me, guess the 4-corner idle circuit is doing its job.
