Joe ,

How goes the project?.....Each of your carbs should have a small spring around the primary throttle shaft, this will close the carb if your linkage is adjusted properly.

If you can not adjust this out with the linkage you may have to remove your carb and adjust the throttle stop underneath .

The location of the slot on your rear linkage just depends on how you want to drive your car, take all the slack out for max performance, or put in all the slack and you can drive on two barrels and save a lot of fuel when you want to.
