Alright, most of my research has been inconclusive, can the question be put to rest? Is what the gas tank says the best mixture? (4 ounces of oil to a gallon) (32:1)? That's what I've been using, bone stock setup even with the gurtner carb. Is 40:1 better? Hopefully these questions can be answered and more in this thread.
Additional helpful information?
I'm running an NGK B6HS and swapped out the sparkplug cap with an NGK cap. I have a 50v, if that's relevant.
