I just installed the charge bar on my standard autodisk, and sure enough, at very low settings, like light 380 loads, it gets erratic. The thrown weight drifts all over the place, and sometimes it doesn't even charge at all.
I see why. At the minimum settings, the tiny opening in the charge bar doesn't fall exactly under the hole in the bottom of the hopper. The groove that the bellcrank that moves the disk or charge bar doesn't extend quite far enough to allow the charge bar to move the charge bar directly under the hole in the hopper.
Here's a fix.
Disassemble the autodisk, and deepen the slot in the body where the bellcrank moves the charge bar or disk. The edge of a standard six or eight inch file does the job nicely. You only need to remove maybe .08 inch of metal on the top of the slot. Here's how mine looks now.
You may also have to remove a bit of metal where the spring leg of the bellcrank contacts the body. Again, not more than a tenth of an inch or so. Here.
Now, the gap where the body meets the riser should be minimal, like this.
I don't think you can overdo it, but a little trial and error will assure that you don't remove too much metal. Do some filing, and then reassemble the whole thing and check the alignment of the hole in the autodisk with the bottom hole in the hopper. When you finish, it should line up pretty much like this. Nice consistent 2 -3 gr charges now.
