One thing I can say for Opti-2 is that the piston was not stuck like the one in the weed eater video when I pulled it out of the cylinder but came out easy. After this I will follow manufacturer recommendation and not exceed 40:1, even when using up the other 8 packets of Opti-2 I have left.
What engine is that a CAG?
That isnt even the China girl engine that I was under the impresion you had....doesnt matter though, Opti 2 wasnt your problem either way guaranteed............you have other issues at play with your engine problems.
