My experience with the Crossfire is the carb needs to be really clean, especially the main jet. You can find the jet under the bowl.
Have you tried using starting fluid to see if you can at least get it to fire? Have you checked to see if the plug is firing?
Don't to forget (like I did when I first got mine) to turn the kill switch on? Also, some models required the brake pedal to be pressed. Do the brakes work? If there isn't enough pressure in the system the switch on the master cylinder will not work. A jumper wire across the terminals will bypass it.
