Looking for a picture or description how the thermostat is connected to the throttle body of a ljet motor (maybe the same a djet setup). What other components are involved in the warm-up circuit of a ljet motor?
Thanks...if you got a picture, all the better.

I believe the top lever on the TB is for attaching the "emergency" return spring (IMG:style_emoticons/default/smile.gif)

If you don't get a rise in RPMs at start up; pull the AAR and see if it's working. While cool, the orofice ( hole ) in the AAR is approc 1/3 open. Hook it up to a 12volt source and watch it close. Mine take an average of 1 1/2 minutes to close from ambient temp. If you put the AAR in the refrigerator ( or freezer ), the orofice will open even wider as the temp drops. WD40 is a safe lubricant for it

I get a a rise in RPMS to about 1600 until the AAR closes, then the drop back to 900 as the AAR closes.

Good thing is that it's easy to test.
