1/4 turn towards leanon the low end needle? If that doesn't clear the problem should I continue to go lean?

I have tried a more lean setting on the low end needle and instead of stumbling, the engine just cuts out when idling a short time (less than 15 seconds) and then WOT is demanded.

It does not smoke when rev'ing from idle but it does have some oil in the flow. Is that what your calling smoke? I assumed that when moving the throttle quickly, some un-burned oil was going to come out of the exhaust.</p>
