Guys, I hate to spoil your day, but if the engine is at idle and you plug the exhaust you are not flooding the engine with fuel to stop it, you are blocking off the exhaust creating back pressure. Unless you have a check valve in the pressure line from the exhaust the pressure bleeds off rather quickly and will not continue to force fuel into the carb, if you have that problem you have bigger problems than worrying about the best way to stop an engine. As far as the argument that you are spiking the pressure in the tank back thru the pressure line, momentarily you are, if it get too high the lid pops up releasing it. You only have to think about how little fuel is going into the engine at idle and how fast you plugging and unplugging the stinger.

dalolyn, on every off road vehicle I have ever driven the vast majority of times I have been able to tell when the fuel was running out before the engine quit, unless it was in a race with nine other noisy trucks running. With the jumps and roughness of the track the fuel does not tend to stay exactly by the pickup, even on the best designed tanks.
