Just tried that and now when you remove the glow starter it runs for 10 seconds then just stalls. If it doesn't rev high then it stalls. I'm really confused, I know little adjustments make a big difference but this nitro just doesn't seem to want to idle

Hi I've just bought my first nitro a hpi 3.5 trophy. After reading the manual I began the break in process. Car is in base setting with full tank of fuel and primed. A couple of pulls and she starts up and that's where the problem starts. It wants to rev high and not just a little high it wants to rev flat out. So I block the exhaust and shut it off. I've now been through everything from checking base settings, idle gap, glow plug and every time I start it all it wants to do is rev flat out. What should I do as I don't want to knacker the engine as its not even broken in yet.
