Idle control solenoid

[Snowbound]

Just getting to know my 'new' 69 FJ45 and noticed this lonely wire on the carb. Thanks to the mighty resources of this great forum and a parts diagram, I now know the name of the thing it is attached to even if I don't really understand what it does!!! From what I can gather there should be two wires and this is the earth/ground.

As the motor starts and runs should I do anything about it? As far as I know this is the original Aisan carb.

it switches idle fuel on or off, if it stops functioning it wont idle at all.

Admittedly I haven't run it much but it does idle, presumably without any help from the solenoid in its current state.

This solenoid when energized lets the fuel flow through the idle circuit. It is energized when the ignition is on.
Its purpose is to help STOP the engine when the ignition is turned off.

Some people have bypassed the solenoid by cutting the tip off with wire cutters. This lets fuel through whether the solenoid is working or not.
You may have one of these.

Thanks for all the info. As it seems to be working at the moment, I will leave it alone, until I get round to a carb refurb. Unless Toyota ran a limited edition 'Black Carb' in 1969, I think this may be a little over due.

69 carbs were problematic. Do you have a solenoid like this also?

Here it is in all its glory!

I didn't know they came in black.
