    I was reading technical stuff regarding the topic compression to satisfy my own curiosity.
    I did come across something that may be of some help here.

    Again assuming there is no compression.

    Consecutive Low Compression in All CylindersThis could happen because of fuel washed cylinders, when too much fuel is introduced into the engine and all oil has been washed off the walls of the cylinder. The oil creates a sealing effect between the ring assemblies of the piston and the cylinder walls of the engine block. When this thin layer of oil is washed off, the engine compression escapes into the crankcase. Engines with a flooding problem usually show this behavior.

    Just trying to offer possibilities.

    It lives. Pulled the coil lead out of the dissy cap and got no spark. Swapped coils and got spark to the cap but nothing at the plugs. Fitted a new cap, some clean fuel, a breath of " startyabastard " and a new battery and it coughs into life and idles.

    I always check fuel at the rail first or carb, then SPARK and finally compression.
