I am looking at a '70 beetle. It has a vacuum advance dizzy with electronic ignition which I am not familiar with instead of points and condensor. I can't tell the make. While checking the advance with the homemade Muir lamp I noticed it stayed lit dimly all the way around the clock until it got to about 7.5 and then lit up fully. Is this normal for electric ignitions?
The engine takes takes about 6 seconds to catch although all the tune up settings are good. It idles fine but has an intermittent miss at speed.
