Okay I've read all about the nutter bypass but I still can't seem to get a clear understanding of what to do with the stepper pins on the carter BBD. I've removed the stepper motor and I see the two pins with the spring in the middle. I also included a picture of this.

1. How exactly do I adjust the two pins without breaking them? They look fragile.

2. I read to adjust them to be 1/8" away from the wall of the carb. What's the easiest way to do this without having to put the stepper motor back on the carb to guage my progress?

3. When I'm done, do i need to remove the wire harness from the back even if I adjust the pins manually instead of the idle screw method?

I'm probably overcomplicating this but I'm paranoid I'll break the pins or mess something up.

if you have Nutter bypased AND removed / unplugged the computer, there is no voltage in that plug and those stepper pins are obsolete. However they are connected to the fuel metering so need to be in a position from which you can then balance the idle mixture on teh crews. They then serve no future purpose and you should not adjust idle mixture using them.

You can just push them back by hand or pull them out. with it removed from the carb. Some say to put it to full rich mixture by pulling them all the way out, other say about half way. Does not matter as long as you can get the idle right on the screws.
