Default Re: Oil/gas mix - What is correct and does it very?

16:1 is excessive, but it's not really harmful to have extra oil. I ran 16:1 with weed eater oil at first, and I didn't get any smoke and it seemed to run fine. I did however switch to 24:1 on the next tank, and I'm still using 24:1 just because I don't know whether or not the engine is fully broken-in or not. I do want to get some opti-2 soon and try that out. I suspect it will run better with high-quality synthetic because not only will it require less oil but it really does seem like synthetic causes far less carbon buildup. I scraped some of the carbon off my piston last week, and after a few rides there was already more carbon in its place!
