Hi there, my friend was going to adjust my k-jetronic fuel mixture and he found that i had no mixture adjustment screw. i was wandering if anyone knew where i could buy a new one. cheers

A new screw or a metering unit?
As you won't be able to get just a screw and replace it?

naa the actual screw. I have all the rest, and it seems okay. just dont have the screw. lol. maybe ill have to find someone whos breaking a xr3i.

If the screw is missing your idle fueling will be to shit, if its the same as an Rst which I think it is. Do you mean the thing that sticks out of the metering unit like a little tower with an allen bolt head in that you use to adjust co. If so, you dont need it, bang an Allen key down the hole that's left where it should be and you'll find the screw down there, as this is all the little tower thing does, I.e pushes an Allen key hidden inside the housing down to the adjustment screw.

If i put the allen key in there, it goes quite far then it stalls the engine. which is wierd. :s not really sure

As said the allen key is down the bottom of the tube that stick up, if you put ANY pressure on the allen key through the tube, this will push the air meter flap down and also allow much more fuel through, just rest the allen key in the tube, it's down about 4", and adjust by turning a bit at a time.
