Re: 100:1 Mix
Red and sticky sounds like the stuff they coat certain parts in to either keep from rusting or in the case of aluminum to keep from oxidizing during oversea shipping or time sitting on a shelf. Not saying that is the case here as you would think that stuff would burn off if it was happened to be used, but just sounds strange when you say red and sticky because that sounds nothing like anything I have seen from running opti-2.
My combustion area is not red and sticky, but more like a clean looking tan color sort of similar to what my spark plug looks like. No built up black goo, carbon or white hot spots. Just a nice subtle tan and sparkling clean looking cylinder. I have had the head off two of my engines that were both run on opti-2 and they both looked like very "Happy" clean burning little engines on the inside with no visable signs of wear like scoring or hot running.
