Idler adjusting screw

Postby Kitsune » Wed Dec 14, 2016 6:32 pm

Hey guys, hope everyone is well coming up to the Chrissy break.

Quicker question.
i am apparently missing my Idler adjusting screw and would like to know where I would be able to grab one locally - WA Perth.
I am being told that the butterfly in the throttle body is closing too far - causing it to stick slightly in the closed position. Hence the slightly stiff accelerator.

Any advice would be appreciated.

Also, will there be a run being held over the holidays?

Can't answer what old car runs might be happening over in perth. perhaps one of our western members can jump in on that. as per the throttle plate stop screw. (NOT the idle adjust screw). Just any screw that fits the thread, not real sure on the size mind you, but the idle is controlled by bypass air.
The throttle plate should close all the way, yes there is a stop screw so the butterfly doesn't stick shut. but idle is controlled by the IAC. So get out your taps and figure out what size the tread is, then loc-tite a screw in to hold the butterfly at just closed. Done.

well I have a throttle body that's complete , including worn shaft bushes here ,that's why it was changed out .good news it has the stop screw and even better I just screwed it out ,it has the spring and all . come and get it .

BUT, firstly , just check your throttle body by trying to wiggle the end of the shaft where it attaches to the cable , there should be no movement ,I'm not talking about rotation, just side to side .if there's movement ,well that's not good ! but don't despair..... .

let us know how you go

there's a coffee and cars at the lake where they do the rowing ,just off Tonkin hwy. on Sunday ,we are going

Cheers Barry

That's awesome mate, let me know what ya want for the screw and I will grab it off you on Sunday.
All I need is the address and time of the meeting place as I have no idea as to where they do the rowing z?

Everything else at the throttle body seems good.

Cheers

Luke
