Forgive my ignorance, but I'm still trying to learn nitro cars. As a follow-up to a previous post. I can be running at half throttle just fine, but when I mive to full throttle the engine dies. I've changed out the glow plug and same thing. My thought is that it would have to deal with the amount of fuel getting to the chamber, whether it be too much or too little. In which case I should be toying with the high speed needle. What's wrong with my train of thought.

If it's the clutch setting, how come it runs at medium throttle fine, but when I lay it to it the engine dies.

Thanks again, Duc
