There's nothing like the sound of a nitro engine at full song.
Ever see a top fuel rail at idle? Watch the exhaust stacks. You'll see liquid spitting out, it's unburned fuel.
I saw one 'sneeze" shortly after being fired up. It blew the crankshaft right out the bottom. No joke! The block was shattered like a hand grenade went off inside.If spark momentarily fails early in the run,
unburned nitro builds up in those cylinders and
then explodes with a force that can blow cylinder
heads off the block in pieces or blow the block in
