    I have a Primus 4138 normal burner.
    Small fire is yellow flame.
    Medium fire is ok but red flame.
    When they use big fire and more pump.
    They are blast every ten seconds.
    I guess the burner have leak when it was high pressure.
    Any friend have another imagines ?

    How to find the trouble and deal with it ?
