This will only work on a "smogged" intake manifold.
If you really want to save money, you can make your own water manometer
for just a couple of bucks. All you need is some clear plastic tubing,
and some water. Remove the plugs (or air injectors) from the intake
manifold. Insert the hose, one end into each hole, and use some tape
or something similar to get a good seal. Then you can start the
engine. The difference in water level will show you the difference in
carb balance. It's also much more accurate than a Uni-syn. You can
also check the balance at larger throttle openings as well. Believe it
or not, just because the carbs are synced at idle, doesn't mean they'll
be balanced at higher rpms.
Happy roadstering,
