Throttle part

Hi all,
Does anyone know what this part is called please. It is a little gas strut that pushes the throttle off when the accelerator is released.
Does anyone happen to have a working one laying around, that would be good.
Thanks so much.

I thought the throttle return was the spring that's hidden behind the injection pump, between the injection pump and the engine block. Ask me how i know :P

You could be right, I am no expert.
All that I know is that my engine revs hard even when the throttle is released, upon investigation I discovered that this strut had no gas and could not do its job of closing the throttle.
It pushes up and c;loses the throttle once there is no opposite force from your foot on the pedal.

1 of my diesels uses the GreenPedro gas "strut" and the other a strong spring to force the pump back to idle when released. I would go to a "spring shop" (bunnings if you have to) and buy a strong spring as that strut is probably hard to get. Not too strong as your foot is working against it to hold speed !

Thanks Sharkey,

The spring return is there as well and is probably tired so will look at replacing that as well.

How did you go with the spring replacement ?

I replaced mine with one from bunnings tested to be the same strength and cut the the size needed. was only a couple of dollars.
