Setting the Mixture

Now that your engine is fully broken-in, you can set the high speed needle valve for optimum flight performance.

Note: Be careful to never lean the engine out too much. Remember that the lubricants for your engine are suspended in the fuel. If you lean out the fuel mixture too much you will also be lowering the amount of lubricant entering your engine. Less lubricant means more chance of your engine overheating and possible engine failure.
