Nitro has a steep learning curve, unfortunately.
Return your adjustments to factory settings and start over. Make sure you prime it, leave the igniter on for 10 seconds or so, then let it warm up sufficiently before you give it throttle. Really, you're just going to have to learn the quirks of your particular engine; nitros are as much an art as a science. I have some that will start almost instantly, hot or cold, and require very little adjustment for changes in weather or elevation. I have others that are just a pain in the neck pretty much all the time, hard starting cold and even harder when hot, very sensitive to temperature, humidity and elevation, etc.
