That's exactly what happens. Bike starts easy, idles fine. Wick it on, bogs and dies. I thought it needed more fuel so I went richer (lower the clip) and seemed to make it worse. I will try moving the clip to the top to see what happens.....if I move it to the top, change to a new spark plug and it bogs and dies at full throttle and the plug still very wet, to me this kinda say it's a spark problem.

Norm - I methodically checked MOST of the stuff you write - but I feel like making a list and checking stuff off with notes!
