Dwell angle gets smaller with smaller points gap!

Here is a similar problem and discussion for MG's which are almost the same

Yes, it is opposite of what should happen, hence the puzzlement. I'm pretty sure my meter is correct. + to + of coil, ground to - of coil. Anyways, I'm taking the advice of Malsal. I've already ordered a new electronic distributor. Tired of messing with this thing...wish I had done it before spending a lot of money on trying to fix it.

Weird because that is the opposite of what should happen because a smaller gap should mean the points open later and close sooner, resulting in a longer dwell. A larger gap should result in a shorter dwell. Is the machine wired correctly? The positive should be connected to the coil and negative to a ground. I was thinking about my car last night, which is positive ground, and wondering if it would make a difference which the dwell meter is wired.
Dwell refers to how long the points are closed so closing up the gap increases dewll, giving the coil more time to charge
You would be a lot better off replacing the distributor imo the Duciller is commonly known as junk.
If in doubt, flat out . Colin Mc Rae MBE 1968-2007.
I have a Ducillier dizzy I'm trying to set my points gap on my new points correctly by using a dwell meter. I have the dwell meter connected across the +/- of the coil per the instructions. The initial dwell reading was smaller than the spec value, so I thought this meant that the points gap is too large. So I decreased the gap and got even smaller dwell!. If I increase the gap the dwell gets larger but only to a certain point after which the car doesn't run. I can't get it to the 57 degrees spec. I had measured with the old points and the reading was pretty close to the spec dwell. What could I be doing wrong?
