    Big bang at the start

    When i try to start my engine it allways die after some seconds.
    And then when i try to start it again i hear a big bang in the exhaust pipe...
    It always happen when the engine is cold, never when its warm.

    Why does this happen ?

    I vote to much fuel.....You could have a leaky needle/seat.

    Your ski is 6 years old and needs a carb rebuild/cleaning.

    Mine does the same thing when the Advent ignition is in there, never on the OEM. Could be a leaky needle and seat like MRBTD says.

    If you're backfiring you'd better check your reeds...
