Well I have tried several things to make the draw a little easier, and none have really been effective. I have tried making the hole in the mouthpiece slightly bigger, but no real effect. This is also not a good idea, because if you cut open a mouthpiece, you will see a small extension tube that keeps the inner cart from being pushed to far down. Enlarging the mouthpiece hole can ruin that.
It is NOT caused by the small space between the inner cart and mouthpiece as some have mentioned. I say this, because drawing on it with, or without the inner cart is very close. I have also tried the notches on the inner cart and again, no difference in the draw.
I finally realized the limiting factor is the tiny hole on the battery side of the atty. So I figured if that was a little larger, the draw would be much better.
So with the atty in a small vise, I set up the drill press to limit the hole depth so as not to screw up the guts of the atty. I managed to get the hole mostly drilled, but realized that the positive atty connection (where the hole is), was spinning around. It's only held in place by a tiny plastic grommet which doesn't hold it tight enough to drill out, with out it spinning around.
Long story short. The spinning of the internal positive connector tore the wires and killed the atty. BUT even though the atty doesn't work, the draw is much better compared to my other 401 atty's. So even knowing what the problem is. There still is no real way to correct it, except during the manufacturing process.
