What is the function of the mix jet? In other words, as I unscrew it, will that let more air in or more fuel in? Which way do I turn it to allow more fuel? I want to run richer. The manual says to let the engine idle, then turn it in until it misses, then turn it out until it misses, and set it midway between the two places. Well, if I want to run a little richer, which way do I turn it from midway?

 

Which way makes it richer (more gas, less air). In or out?
