Yes that KE air -flow potentiometer ; very difficult to source out but sorts out all cold start and erratic warm-ups if the track is worn out .
Specific to cold starts only .

those pots are $2 ea at my local pick a part.

If you have a bad air flow potentiometer and one can be replaced with a new one why care if it is china that manufactured it? it might not last as long as the original but what after market item dose? ALL I am asking is there enough interest in it to make it worth my time to offer them! at a good price.

Just-In-Time, I appreciate your thoughtful offer. Those potentiometers are hard to find.

Bought mine from him, for a spare.

yes and I was turned on to this by another member and thought I would make contact with the intention of stocking some, I just thought I would run this by every who keeps the older equipment, but I do not wish to have a :cool:hundred units sitting in limbo.:eek:

If this is for W123 300D 1984 model, I am interested. How much will it cost? Is this brand new or reworked?

On the LED being run from a PWM source.

If strobing is an issue, a capacitor could be added in parallel to the output to smooth things out. Depending on how large the cap is and max current availible from the PWM unit, a resistor might need to be added in series to the cap to limit charging inrush current when things are turned on.

( The resistor might be needed because a capacitor looks like a dead short until it charges up. )
