You just have to ask the question, "how often do you drive with your foot flat
on the floor?"
And if your answer is "often" then you should not be using any "street use"
carb setup. And none of the afore-mentioned methods should be used. You go
to a speed shop to have everything dyna-tuned.
But otherwise, make sure you linkage is not worn, loose, and appropriately
adjusted (as you are basically recommending,) etc. and then the appropriate
method is the UNISYN, or such a device.

Subject: [6pack] synching carbs
James and list. A question - a Unisyn, or similar tool, measures air
flow, right? And, it is almost always used at idle or high idle. So,
the real question is - how often do you drive your car at idle? If the
answer is, "I don't drive at idle", then here is the simple, no meter
needed to synch your carbs. With the engine off, and air filter
removed, have someone sit in the car and plant their foot on the gas
pedal flat to the floor. Using a light and a tool to hold up the carb
piston, raise the piston and check the position of the carb butterfly.
It should be absolutely at right angles to the bore of the carb throat.
Do the same with the next carb. It should be at the same position as
the first one you checked. If both butterfly's are at right angles to
the carb bore and parallel to each other, the carbs are synched at
running position. Note, this has nothing to do with mixture. The
reason for having someone hold the carbs open with the gas pedal, it
eliminates the possibility of the foot pedal not fully opening the
carbs.(WOT wide open throttle) Ted
