Stumble while cruising..

This isnt so much a question. Since I know its either a timing issue, or a carb adjustment issue. I just dont know what to do about it. and its frustrating.
I continually tweak and adjust but it never seems to get better. Just frustrated!!! :evil:

Ive run into this a few times. If it's been awhile, what is ur plug life? Had this simple/confusing fix a few times. New plugs? Good luck.
