Well this is unfortunate but it's most certainly my smoke issue (besides running rich) and I have everything I need already to fix it.
What is the easiest way to fix this? Is there a trick to doing this that doesn't involve removing the head? I definitely don't want a valve falling into a cylinder but it seems a shame to pull everything a part for little o-rings. Perhaps a dowel in the spark plug hole to press up on the valve and slip the ring over the stem with the retainers off? Or doing only the cylinder under compression and rotating the engine as I go? Sounds doable to me but I don't want to make things worse.
