Not sure what kind of idle speed you want, but I heard of a trick once to put a piece of tape on a belt pully on a tractor to find where the PTO speed was. Using a flourescent light, the tape will seem to stop at 600 rpm. Then you can guess at where 540 would be.

I suppose a similar thing would work if you put a mark on a pulley or harmonic balancer. If it will stop at 600 rpm, maybe you can find another multiple of 60Hz that will get you close to your desired idle RPM.
