    I have a Red max hedge trimmer that it just awsome, but after you run it a few minutes and shut it down, it is terrible to start again. I have a worker that can fool around with it, and pull it 40 times trying a variety of choke/prime/ and other combinations but it seems to have no pattern. It works without flaw other then this, any suggestions please?

    Spray some carb cleaner into air intake and see if it will start briefly. If it does the engine is starving for fuel.
    If it doesn't check for spark.
    If you pass these two tests check for a plugged muffler.

    Thanks Jon

    The odd thing is that it will start great if it sets for 15 min or so. I will do some checking on it today.

    Sounds like the gas cap isn't venting properly. Loosen the gas cap the next time this happens and try to start it.

    I have tried that, and it does not help.

    Check for spark when it shuts down. The coil could be getting hot. The way it goes is you start the engine and it runs for 10 to 20 minutes then shuts down and will not restart until the coil cools down so check the spark when it is still hot.
