Re: Choke selenoid hook up on 73 50 hp rude?
Look at the choke solenoid. See the purple/white and purple/yellow wires coming from it? Follow those wires to the terminal strip. Remove the purple/yellow wire COMING FROM THE SOLENOID from it's screw terminal. Leave the other purple/yellow one where it is. It will no longer be connected to anything. Now, connect the wire that you just removed to the screw where the purple/white wires are connected. That will make 3 wires under that screw...two purple/white and one purple/yellow.
Edit: oops, I wasn't finished. Now, when wired this way, you will get full choke when you operate the switch at the control, and none when you let off the switch. In other words, you have full control over the choke operation. You may have to "bump" the switch a few times to keep it running on a cold startup.
However, you may want to reconsider doing this. The original setup provided for an automatic partial choke during warmup. The reason for modifying it is to prevent choking when you don't want it....in warm/hot weather. The warmup feature might be nice in cold weather. It all depends on whether you are having warm-start stalling problems from over choking.
