    pinching the line would be just like the same thing. it would run until theres no moer fuel in the line

    Yea, as long as it's not overheating, but I think most of the time it's not practical to run it all out every time, with different cercumstances (race over, tuning, practicing)

    ya pinching the line is making the motor think its out of fuel because it will run until al the fuel in the line is out

    No,letting it run out fully will make it run on a lean mixture and hot tempetures. Not good to do.

    Whats the difference between pinching the fuel line and it running out of fuel, both are doing the same thing except running dry takes a few seconds longer. The engine will get hotter while you are tuning from a lean mixture than it would running right then running out of fuel.

    for those of you that think that pinching the fuel line is a safe way to shut down an engine here is a story:
    My friend has a xtm 24/7 pro big block in his savage. We are out running or trucks and they are at operating temperature ie 240-260f, so he likes to shut his engine down by pinching the fuel line and I always tell him dont do it you will damage the eninge. He always says no its fine. He brings his truck in and I temp guage it 260f, perfect. He drove it to his feet and pinched the fuel line to shut it down and I walk over to him and zap it again with the temp gun, 330f! I have noticed the same on my engines, pinching the line is ok to check the lsn mixture, but I never do it until it stalls out completely. Most instruction manuals clearly state that (In an emergency) the engine can be stopped by pinching the fuel line, but the also clearly state that this can damage your engine. Just some food for thought.

    The only time you should not starve the engine is during break-in, first couple of tanks.
