Have been doing so reading about pop off pressure. Seems that a pop to high will cause some of the problems I have. Not holding a tune or not coming down smooth from full throttle. Think I will try and raise the inlet lever a little and reduce some spring tension and see what happens. Hope it will drop the pop some.

Higher pop = lean
Lower pop = rich
FEAR NO TREE. FEAR GOD.
