Guys - you have it all wrong here...a flame out is something you -DO NOT WANT.

It is not when a flame comes out of your exhaust. It just means that your engine was running so lean that there was either no fuel left to burn in the engine or no lubrication and it seized. If you have a bad glow plug your engine may stop upon slight impacts or turns but that is fine. Flame outs occur mostly on high speed runs.

You will not be able to get flames to come from your exhaust - sorry to dissappoint you.
