There are no factory carb settings. There is no way that the factory folks can know where the centerline of your fuel tank will be in relation to the carb's spraybar. Furthermore, they can't possibly know what brand of fuel you will be using, nor will they have any idea of its contents. Additionally, even the best guessers in the business can't possibly know what kind of propeller load your engine will be expected to deal with. In other words - there is no way that the factory can anticipate what your engine will need as far as carb settings go. Our model engines are unlike any other IC engines that we are likely to encounter in our lives.

Now I'm not saying that you do not know this information. I am writing it here for those that do not know this information. Forget "factory settings" when it comes to glow engines. There aren't any.
