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.

You would be a lot better off replacing the distributor imo the Duciller is commonly known as junk.

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?
