What should our EA81 cars or brats idle at when started? And is there a difference for ones with AC Vs. NO AC????

MY 84 wagon when I start it will idle at 1000 RPM.

My 85 Brat wants to idle at 500 RPM's. But the Brat runs rough at this idle speed.. Should I just turn up the throttle screw a bit???

Thanks Again ALL.. Joe

700 to 900 is the "official" idle for EA81. However, if you have a/c in your Brat it could be the a/c relay is not kicking in to raise the idle back to normal.

Hmmm my 90 brumby idles about 1200-1300 rpm when warm and thats the lowest it can go: there is still some adjustment left in the screw but the throttle cable plate wont go any further back.

Does this mean its running rich, or sumthin wrong wif the carb?
