    ok,
    1st issue (solved), fuel shutoff valve broken. this caused more than
    a weekend of frustration. the vacum fuel shutoff from manifold had
    been sucking gas right outta the tank, not opening the fuel supply.
    the result (first missdiagnosed as sticky float neadle) was that it
    was flooded. extremly difficult to start, when it did, it would run
    ten seconds of so then start belching out gas (dirty/oily gas), then
    choke n die. allright. fix that. how much gas has this thing drank?
    has it choked all it back up? ??? with this fuel supplyline switchy
    thing fixed. we try to start again... same. starts way tooo hard,
    runs olny with full throttle sputtering to a build up only puke up an
    oily gassey mess. yup. then descide to drain the oil, hmmm, could
    there be too much oil in here? ?? what drains out is more gas than
    oil, maybe close to four litres of it. thats where the pretty little
    stands right now...
    my question is this, did this whole episode blow out some sorta oil
    seal or something? could too much oil in have blown a seal (like that
    old vw i once had). would suckin down that much perol result in that
    sorta action, expectedly? is it ok? just pust some fresh oil in it
    and good? or does that hypothetically blown seal have to be replaced?

    You probably didn't blow a seal out because your engine has a crankcase
    breather system that lets excess air pressure escape into the airbox...

    You probably have an oil-soaked air filter at this time, and oil in the
    airbox. Look for a hose at the bottom of the airbox which might be
    there. It might be like an appendix, no outlet. If you have a hose like
    that, drain it, and clean your air filter...

    The worse thing that can happen when you have a crankcase full of
    gasoline is an explosion. That happened to a guy I know. His carb float
    didn't shut off the gas properly and the gas leaked into his oil pan.
    When he tried to start the engine, the gas in the pan exploded and blew
    the pan right off the engine...

    Another bad problem with gas in the oil is that it doesn't lubricate
    your bearings very well, it allows metal to metal contact between the
    crankshaft and the bearings and they wear quickly...

    So, I would recommend cleaning the air filter and airbox, draining the
    appendix, refilling the engine with oil and go ahead and start it and
    let the oil circulate good before you rev the engine up to high RPM...

    Then there was Ernest Hemingway who wrote whole novels without any
    punctuation at all I think he did that in a book called The Green Hills
    of Africa or some such It was up to the reader to guess where sentences
    begans and ended And he was a very successful writer
