    Hi Guys,

    After tinkering with the idle adjustment on the carb, my hand-held tach said that I was idling (warm) at about 750rpm. It seems to feel okay, but since I haven't been able to find any info, I thought I'd ask you guys: Is this normal?

    Thanks!

    That is about perfect if its in gear. If not it might be around 500 rpm or so while in gear. If so, it might stumble a little bit, espessialy with the AC on. I set my idle at about 650-700 in gear, and about 800 out of gear while warm, but that is what i prefer.

    When all else fails... Check the blinker fluid.
