    Lost compression in #3 cylinder !!! :(

    Lost compression in #3.
    It was running smooth @ 8700rpms with a twin prop.
    There was no loss of power while running.
    I did a compression check because i had oil on my plugs.
    Looks like the oil was coming from a bad O ring in the supercharger.

    looks like detonation killed it...the tiny specks look like aluminum particles from overheating. either way it looks like your milk money is gonna go toward parts....good luck
