What do you mean what happens when the engine dies? It just like stops no high revs and then stops it just stops. The engine has little over a gallon through it. I'm using 20% nitro, blue thunder. I'm using o.s. 8 glow plugs and the engine has great compression. Well the factory settings won't work because the engine it was factory set for was the .21 and I'm running it on the .25. I'll try the high speed thing you recommended but it doesn't do either of gurgling or pings before it reaches idle. It just stops. Thanks any advice.
