    fuel problem, good gas, check carbs, check fuel pump.
    do comp check, spark check, and then did the fuel checks.

    I agree with coueytwo...it sounds like a fuel problem. How old is the fuel? Is it hard to start? When was the carb cleaned and who did it?

    the fuel was just baught,and for the carb it was serviced by a qualified mec before purchase.

    What model is this engine?
    Does it have a sensor assembly?
