<VV> Using a Unisync

[Harry Yarnell]

Basically, you place the Unisyn over one carb running at idle. Dial the knob 
untill the floating ball is in the center, and then move the unisyn to the 
other carb. The ball should be in the same place. If not, adjust the idle 
screws on one (or both) until the ball is centered. and the idle speed is 
what you want. The crossshaft linkage should be disconnected to the carbs, 
so the carbs work independant of each other.
The ball going higher in the tube indicates that carb is pulling more air 
than the other. The converse is true; lower, less air.
