Autolite 1100 on 200 inline six

[DON]

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 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.
I may be wrong on this, it just a glimpse in the video. Just checking and assuming you are showing the dwell reading

I am going by this clip of the video. It looks like the meter is set at the 6cyl rpm setting

Dear Members, I would like to thank all of you for sharing your knowledge and experiences with this newby. As you indicated Don I had the button of the instrument in the wrong position and I was dumbfounded that I coud not get a steady dwell reading with increased RPM. So this Pm I went and checked carefully and did find that at all times the button was in the wrong place, thereby the dwell is nor steady at 40 deg. Thanks for the suggestion.
Now I am in thep process of adjusting the carb as the car is runnung rich.
Thank you again without your help and assistance I would have been lost in getting the car going.
Blessings

It does look like a nice piece of equipment for a points distributor

Don, thank you for your comment.
Now I am trying to adjust the carburator and thanks to Frank and thers I was able to get the ignition part in line.
On starting the car there is an intial blow of black smoke that stains the ground, It s definitely a rich condition and number one spark is also black. When I repaired the carb the float level was set at 1 3/32 in and everything else in accordance with theFord manual specs. Is there another reason for having a rich mixture? Car at idle RPM is somewhat rough. THe fuel mixture screw does nothing to fine tune the Idle RPM. Do not know what else to do or try.
Your comments will be appreciated.

Just some info.
For the most part, if the carb is set rich, all the plugs will read rich, maybe not exactly the same, but blacker than normal.
It does sound like you have a carb issue. Others who are more familiar with the lom carb can chime in. Make sure your throttle stop screw (idle speed) is not too far in. If the idle speed screw is too far in, and your idle speed is at an acceptable speed, it is covering / compensating for a problem. It holds the butterfly valve open past the idle speed circuit ports making the idle speed screw not function and make no difference when it is turned. Having set a while, I would check the low speed jets and passages. Make sure the didn’t get clogged from setting (gas with ethanol is bad about that). I would also pull the plug wire off on the cylinder that is black ( I think it was number 1 cylinder). MAKE SURE you use insulated pliers and leather gloves help too, so you don’t get bit!!! You should notice it start running rougher and idle speed drop. If it makes little changes or no change, That will tell you if it is a miss on that cylinder.
Maybe check the compression too. That can cause a fouled plug or a miss symptom.

The carb was repaired recently and adjusted to Ford"s manual. Throttle screw is just touching the carb body. I am using ethanol free gasoline as recommended earlier in this chat and it has a new gas tank as well. I will try pulling the No 1 wire out and see how it reacts.
Thank you for your comments.
