    The advance springs on the distributor do allow for some movement. Check for 12 volts at the coil. Make sure the points are opening and closing.

    It is, yes. The shaft is solid and has no free play, it's just the rotor that rotates around the shaft. The flat notch on the inside of the rotor that is supposed to mate with the flat cutout on the dizzy shaft is a different size and so the rotor does not fit tightly on the shaft. I have a feeling it might be the wrong part. It looks like this part:

    But I'm not sure if it's actually the right one.

    Could someone please get me a part number or link to the correct rotor?

    I also ordered this new distributor:

    Is that the correct part? I figured it was cheap enough to give it a try. It has dual points whereas the one I have is single point.

    The coil does have 12V, thought I'm not certain what's coming out of it. The point does open and close. It's a single point distributor.

    Where does the distributor ground wire go? I was just assuming it was grounded, does it need to go to coil neg lead?

    True. I may have imagined that he is seeing more movement than that.

    Pretty sure the green wire from the distributor goes to the negative side of the coil. Download a wiring diagram from this site and double check.

    If I was to go looking for a new coil, which one should I get?

    This one?: http://www.autozone.com/ignition-tun...706117_0_17367

    Before you do that, troubleshoot with what you have.

    Re: "resurrecting" a Scorpion for 24 Hours of LeMons

    Engine now runs and sounds quite good! I got a new coil and also realized I had the dizzy wired incorrectly, hence the no-spark situation.

    I still have not solved the twisty rotor, I suspect it's simply the wrong part but don't know which one I should get. But, it still apparently works well enough to run the engine. My next step is to set the distributor timing. I don't fully understand how it all works yet, but I had planned to not run any vacuum or coolant hoses to the carburetor and the dizzy doesn't have vacuum advance. Any suggestions on timing settings to bias towards power band in the upper rev range? Should I go with stock recommended timing or slightly more advanced or retarded by dialing in the dizzy?

    The car has been away for several months now getting a roll cage installed. The delays are unbelievable, we were supposed to have it back over 3 months ago! At this point, I don't think we'll make it to the next race which is at the end of September in Buttonwillow, so we will likely have to wait until the December race in Sonoma to get it on the track. Two weekends is likely not enough to put together the ENTIRE car.

    The first thing I would do is source an electronic distributor. There is a vendor selling a new one for less than 120.00 change the gear on yours to this one, as your gear is cut in the opposite direction, and yes they fit. this will solve any ignition issues you may have. set the timing for the maximum advance you want and were it goes at idle doesnt matter as this is a race car. fyi, in my 124 coupe race cars i set the max advance at 35 degrees and it was fabulous.
