#1 carb mot syncing

What would cause #1 carb to not register on carbtune sync rods
We have compression and vacuum at port.neddle and seats bad leak in into fuel into air box

Check the hose to the carbtune for cracks. Sounds like you need to pull your carbs clean em. Check your oil for the smell of gas as well if your carbs are leaking.

If it is open a LOT farther than the others, it will have lower vacuun levels.

Is the idle really uneven, possibly even sounding like it's running on just one cylinder?
if it does, it's running on #1.

You've got to fix the fuel leaking at carb #1 first. My guess is #1 is drowning with fuel and you're running on 2 through 4. No sense in trying to sync the carbs until then.
