Scott,

Thanks for the descriptions. I did some more research and found that MB put a signal pickup shoe on terminal block 7 which lies on the inside fender just below the series resistors. If you follow the low signal green wire from the back side of the distributor, it ends at this terminal block. When I measured dwell and idle RPM from there, I had more reasonable dwell readings to work with.

As you said, it is frustrating to get the distributor shaft to a good adjustment point. In the end, I was able to clean up the distributor and points and adjust everything to spec. I noticed an improvement in throttle response and a smoother idle.

By the way, that Bosch MM is a good one for D-Jet.
