    Half right, fleetwin. The slow speed needle adjusts the mixture by varying the amount of air, and yes screwing it in cuts off the air, making it richer or “backwards” but Evinrude reversed “backwards” to “forwards” by putting left hand threads on it. Smart, eh? Normal opening is around 3/4 turn.
