MT Throttle bodies balancing procedure
All bleed screws must be screwed fully in.

1. With engine running, match the butterfly from each pair of bodies that has the highest vaccum reading to the highest of the two using the lever arm adjustment between the bodies. This will balance the bodies together.

2. Then unscrew the bleed screw from the butterfly with the lowest vaccum reading on each pair of bodies to match the reading from no. 1

Example

Adjust no.1 from 6Kp/hr to read same as no.4 @ 8 Kp/hr & then using bleed screws adjust no.2 & no.3 to read 8 Kp/hr
