If the throttle plates are not synchronized at an idle, they will not be synchronized at part throttle. This won’t be as important to a drag racer who launches his vehicle from wide open throttle as it is for oval track, road, or off-road racing where this can mean the difference of who gets out of the corner first. HOW TO USE THE UNI-SYN Make sure there is good seal between the Uni-Syn and the ramtube. On Manifolds WITHOUT Kinsler Spring- Screw Linkage: With the engine idling, place the Uni-Syn over the top of one ramtube on the left side of the engine, while keeping the sight tube vertical. Adjust the flow control wheel in the center of Uni-Syn until the float is halfway up the sight tube. Check the rest of the cylinders on the left side of the engine to get an average reading. Now check the cylinders on the right side and adjust the cross hex link until the average readings are the same on both sides. If you are unable to achieve similar average readings, see section on MANIFOLD INSTALLATION AND SETUP on Page #50. On Manifolds with Kinsler Spring-Screw Linkage: Synchronize the front and rear throttles on the left side of the engine using screw “L”. Now synchronize the front and rear throttles on the right by using screw “R”. Now synchronize the left side to the right side by adjusting the cross hex link. Kinsler’s spring-screw linkage can be installed on most injection manifolds, see section on KINSLER BILLET SPRING-SCREW UNIVERSAL THROTTLE SHAFT LINKS on Pages #60-61. TAKE THE GUESS WORK OUT OF SYNCHRONIZING YOUR THROTTLES OR CARBS AT AN IDLE ! #6002 HOW THE UNIT WORKS The Uni-Syn ® has a swiveling sight tube, so the unit can be used at any angle. The sight tube must be vertical. Air flowing between the flow control wheel and the housing creates a depression (vacuum), which pulls the float up the tapered sight tube. Rotating the wheel clockwise lowers it in the housing’s tapered bore. This increases the vacuum signal, which raises the float in the sight tube. © 2017 6002 Uni-Syn throttle synchronizer, 2 3/4" dia. foam lined base 5995 Adapter biscuit for #6002, foam disk with self-adhesive backing, 1/2" thick x 3 1/2" O.D. for larger ramtubes 6001 Adapter plate for #6002, aluminum plate with foam, fits ramtube bell up to 5 1/8" outside diameter R Reasonable synchronization is if all the flow checks are within 3/4”, the distance between any two lines on the sight tube.
