I noticed in the video you switched the top switch, which according to the bottom switch I looks like you are in the tach mode. So you are switching from the 6k range to the 12k range. You need to have the bottom switch in the points/dwell position and then switch the top one between points and dwell.Frank, ran some tests on the car with the following results:
RPM Dwell Gap Point
1200 60 .028 in (1200 RPM when car just started)
1200 60+ .030
1200 59 .022
1000 53 .022
800 40 .022
600 25 .022
800 40 .022
Car idled rough at 800 rpm and worse at 600 rpm but did not die.
Enclosed video.
Regards,
I may be wrong on this, it just a glimpse in the video. Just checking and assuming you are showing the dwell reading
