    240260280, is your jet alignment tool primarily for the 4 screw dome carbs, or for either the 3 screw of 4 screw?  I can see how it would adjust the nozzle in the 4 screw carb to sit in the appropriate position.  I am trying to understand how it would benefit for the 3 screw, as you would have to take the dome and piston out to put the needle in, which would undo your adjustments.

    It is for aligning the nozzle sleeve (that holds the jet) to the centre of the piston. If you disassemble the bottom of the carb, you will find the nozzle sleeve has freedom to be repositioned within the nozzle sleeve set screw:

    So, rightfully, your next restoration project should be a Morgan.

    He should start easy with Porsche floor boards. No pedal to the metal there.

    It's "Slosh".  When the car accelerates, the fuel sloshes to the back side of the bowl, when the car decelerates, the fuel sloshes to the front. This causes the float to change its height slightly. The acceleration also affects the float.

    If acceleration of water places more at the back wall of the bowl, the water pressure will push the float towards the front of the bowl (put a rubber duck in a bucket of water then spin it on a turntable. The Duck will be forced towards the centre|).

    It is a very complex physics problem and the key is that it affects both carbs in the opposite way due to hinge location asymmetry.
