So today I was fixing an unrealated problem on my S4 TII when I noticed that the, I think it's called, idle screw is missing. It is located near where the throttle cable attaches, so passenger side aft of the TB. Complete opposite side of the TPS adjustment screw. Does anyone know what thread size it is or where i can find another screw? I will post pics tomorrow after i get from work. Thanks!

 

Picture needed. The throttle stop screw and the one to adjust how the thermowax cam engages are in the area you describe. The TII TB has no "idle screw" like what's found on an NA TB. It's on the BAC instead.

 

So it is the screw that all threads say do not touch. But I will post a picture when i'm out of work. Thanks!

 

The location is in front of the dampener.

 

Missing throttle stop screw. After the thermowax cam disengages, the throttle assembly will hit that screw to sit at ~750 RPM. Without it, idle will probably be low. It's a phillips head screw with a spring to keep it from vibrating loose, but I don't have the size/threads. If you have a tap set, you can figure it out.

 

yea that's what i figured. I didn't want to tap because of location but i think that is what i will be doing. Thanks for the help.

 

it must be a jsec motor

 

Yes it is
