Evinrude 35 1977 - Ignition wiring - Help!

[newbboater]

I have seen the wiring diagram below but I have some questions...1. My ignition switch has 4 poles which are not marked but I have determined what each does. Bat-Red, Solenoid-White. With these 2 connected the motor starts and runs. The other 2 poles... one is always hot and the other is hot when in the on position. This last one is accessory. Why is the one pole always hot?2. The most important question is I do not seem to have the Brown/White wire for the choke but I do have a purple/white. Is this the choke? is my choke only manual (there is a white choke knob on the motor). With the current wiring I have to have the choke knob pulled all the way out to start and run and when I get to 3/4 throttle it boggs and stalls. I do have a choke toggle on the dash from the previous motor. If the purple/white is a choke wire what is the complete circuit to the toggle (one pole to purple/white the other goes to ground or hot?) 3. I ran the black wire to body ground but should it just be running it to a kill switch with Black/Yellow?B (Bat) = RedC (Choke) = Brown/white stripeA (Accessories) = Anything you want 12 volts applied to when the key is in the ON position.S (Solenoid) = whiteM (Magneto) = BlackM (Magneto) = Black/Yellow stripeAny help appreciated!

The black wire on the "M" terminal should be a ground wire. It grounds the magneto and kills the engine. All black wires are ground wires.c/6Hooty
