Re: New and Inexperienced :D
for the fuel/oil mix i use 32:1 break in and running it. i have had no issues mine is a 66/80 cc grubee as well. definitely sounds like a carb issue for the bogging down, check the spark plug color to see if its lean or fouled . if its too lean it will be white or a really light color, if its brown without gunk all over it its about right, if its black with a bunch of gunk you are running to rich. Fuel air mix can be changed by the needle clip setting.
