I had the chance to tear down a few of my 80:1 mixed 4stroke machines to decarbonize the heads besides a little gunk on the top of the pistons the insides of the motors were clean and juicey. I dont care what oil you run your gonna get carbon and ash buildup. all I can say is there shouldnt be such thing as a 4 stroke that you have to mix oil, carbon buildup isnt bad on the head of a 2 stroke but when it builds up on the head of the 4 strokes it starts holding the exaust valve open and there goes all the power. wow what a rant its just i've been slammed at work dealing with this issue i have 20 engines i have to tear down sometime this month.
