    88 honda accord LX, Carb, adjustable valves. One cylinder has very
    little compression, 55
    compared to 170 for the other three. Is there a trick to determine
    whether it is the valves or the piston that is leaking compression? I
    put on a new head gasket and it make no diff. Your knowledge and help
    is welcomed and appreciated.
    regards
    david

    Squirt a teaspon (~5cc/ml) of 2stroke oil through
    the spark plug hole. You can use regular oil, but
    it burns very dirty and might add to your problems.
    If the cylinder rings are worn, this will seal them
    long enough for a test.

    Are you sure the new gasket is one correctly, with
    the proer torque?

    add a spoonful of oil to the spark plug hole of the low cylinder. if the
    pressure rises now, its your rings. if it doesnt? valves. or cylinder
    head gasket...

    For a more definitive answer, do a leak-down test, or have one done if you
    don't have an air compressor. If you do, the tester (gauge and a regulator)
    can be bought for $55-$90 at various places online, including Ebay.
