James:
I use the hose method. Get a chunk of hose and use it like a
stethoscope -
and listen to the hissing from each carburetor. Tweak the idle speed until the
volume of the hissing from each carb is equal. The carb meter has not worked
for me since I rebuilt my motor. The idle vacuum is too weak with the cam to
support the vacuum gauge. For that matter, I cannot use the lift the slide
technique to set the mixture either, and for the same reason.
Having said that, I must ask why you can use the meter on one carb, but
not
the other. You need to check your carb diaphragm to see if it is torn or has a
pinhole. You will need to stretch the diaphragm to make sure, you cannot
depend on just a visual inspection.
You should fix whatever is causing the two carbs to behave differently.

Subject: [6pack] Help with Sync'ing those darn carbs...II
So I forgot to mention, I did have the linkage loosened so each carb would
move independently. so my method has been to adjust the idle screw and tweak
the jet needle. then i place the unisync over one carb, adjust the wheel so
the float
is in the middle-ish and then place over the other carb. but it either makes
the other
carb stall out or race. the ball of course is way off and does not much the
other carb.
well, i probably just need to fiddle around. just wish there was a formula!
LOL!
and maybe to a degree there is...either the idle screw or needle.
