I don't know for sure, as my tach doesn't work, despite my desperate and multiple attempts at getting it to do so. (new cluster pod AND amplifier, still no reading!!) Our '83 idles close to 900 or so, and I know mine runs slower because it just sounds slower, I am guessing probably like 650-700 tops....there is an audible difference between the two.....what is the optimum rpm? I also live in a cold climate here....(GR, Michigan) so a slightly higher idle would be a nice thing to help it along when its super cold out. I even installed a new glow plug relay and plugs about 4 months ago, one of the "extended" glow systems, it glows for like 2-3 minutes....didn't help with the cold startup however.
