    an additional thought for compression test is to have the throttle wide open when performing your test

    I was under the impression that you don’t need the throttle wide open for a compression
    test on a two cycle engine. Perhaps because of the porting? I don’t
    understand the difference, but hopefully someone can explain.

    Prepare to be boarded!
