    Default WL pistons

    I have been using Army surplus pistons in my 42 WLA. They are very noisy, and I think I heard once there might have been problems with those. So I wonder if anyone on here has a suggestion for a quieter piston? Thanks, Victor

    I have used original and new pistons with success.
    .002" to .0025 clearance on a fresh bore will be best.
    The engines are noisy compared to anything modern.
