I picked up a 12 ft jon boat, trailer and 4 HP Evinrude. I mainly got it to allow us to get to some of the local springs on the Santa Fe and other local rivers that don't have land access.
The motor is pre-1970 I think but is excellent shape functionally and cosmetically. However it has some mystery controls. Besides the throttle lever and choke there are two knobs. One I think I've figured out- it has a RICHER -> label with arrow so I'm thinking it controls the air/fuel mix.
The other one above the richer knob just has four markings: 1,3,5 and 7. One number in each quadrant of the knob. The plate that would have labels for these is gone.
That has me stumped. Any ideas out there?
I assume I should set the air/fuel mix to rich when starting and turn it down to lean once the motor heats up. Is that correct?
The motor starts on the first pull right now. It will stall if I move the mystery knob up from 1 to 7.
Thanks for any suggestions
