I'm working on getting Dad's aluminum boat ready to take out for the first time in bout 5 years, he bought a 5hp evinrude angler outboard for it. We're not sure what the "low speed mixture" knob is for. It's right by the choke, and can be seen on the attached pic. Probably something simple, we've just never run a motor that old before. Also, our mercury has the throttle in the control arm, while this one has a lever that controls all of it. Does anyone know where the neutral setting would be? It's gotta be somewhere along the throttle settings. Just wondering so that when we start it up on his pond to check it out we don't end up jumping the bank and lookin like morons sitting in a boat in the middle of a hayfield lol.
