Mk2 throttle body

I have a manifold widened out and a mk2 throttle body to fit to my 1.6 EG engine mk1.

Notices the idle adjuster screw is missing from the throttle body.

They a near impossible to find.

Question is - do I need it. Given I am running bosh K jet.

There might be one on the mk1 body I can swap into a it but have not had chance to look at it just yet.

Thx

Have you got a picture? Without the idle screw you'll just be letting air bypass the k-jet air flow plate, as its open to the atmosphere. Unless you are referring to the throttle stop screw which you shouldn't use for adjusting idle anyway.

Found and ordered this one.

Worth a punt for less than £20.

But I believe this is what is missing from my throttle body.

That is the Idle by-pass Screw.  without it you have a large Vacuum leak.

mine looks more like:

And I wrap the threads of the thing with Teflon Tape.
