A guy at work told me to count threads when taking them apart and u should be pretty close when putting them back together. Any other tips
You may want to turn the air screws in gently while counting. Gently. The starting point for adjustment is usually 1 turn out from seated (gently). It's also easier to find where the screw is seated than when it's out entirely. When reassembling it's harder to figure out when to start counting when putting the screw in, so put it all the way in (gently) then back out one turn (or however many turns yours were out originally.
If you don't have to unscrew the choke rods you may want to pass on them. Otherwise, get good measurements on the distance. It's another place where it's hard to count.
The rods from the slides to the throttle arms don't have to be exactly what they are now, but all carbs have to be the same. Just look at the top to see if the rod sticks up a little or sticks up several threads. When i reassemble i hang the rack of carbs in a window and make the tiny crescents of light at the bottom of the slides equal. If the whole rack is a little different from the way it is now, you can acjust with the throttle rocker adjustment.
I cannot think of anything else where counting or measuring is required. That air screw is the only one I count.
