GENERAL INSTRUCTIONS
The UNI-SYNC Is An Instrument For Balancing Multiple Carburetors Of Virtually Any Type Whether Vertically Or Laterally Positioned
TO OPERATE
Warm Engine To Normal Operating Temperatures.
Remove Air Cleaner; Disconnect Linkage.
Place UNI-SYNC Over Throat Of One Carburetor.
With Adjusting Screw (A) In Open Position, Gradually Turn Down Until Float (B) In Tube (C) Rises To, Or Near, Any Graduating Mark.
Without Changing Position Of Adjust Screw Place UNI-SYNC On Remaining Carburetors, Adjusting Each Carburetor Throttle-Stop-Screw To Bring Float (B) To Approximately Same Level As In Step 4.
If The Idling Speed Is Too Fast, Back Off The Throttle Stop Screw On One Carburetor Adjust The UNI-SYNC To That Carburetor, And then Rebalance The Other Carburetors. Now Carefully Reconnect Linkage.
At This Time The Motor Speed Is Increased Just Enough So The Carburetor Control Arms Do Not Touch The Top Screws, Then Locking The Accelerating Control At A Point That Will Not Affect The Linkage To The Carburetor. The Linkage May Then Be Checked And Adjusted By Using The UNI-SYNC In The Same Manner As For Adjusting The Idle Screws.

Worked great on my snowmobile ! I reset the idles on my three carbs and it purrs like a kitten at idle and even smoother at high speeds All three carbs are tuned together! It made a big difference ! Easy to use and can be used on many other types!

1 start because it's a white box item that SAYS it's an EMPI part. Doesn't work. I have to practically close it off to get the orange pill to even kind of move. By then the engine is trying to die. Also this is NOT a UNI-SYN branded item as the description leads you to believe. And OF COURSE I missed the cut off window for return.

This is something you don’t need to use often unless you are a mechanic. I am not a mechanic but have a few dual carbureted cars. It was exactly what I needed at a great price and well constructed.

Worked great to sync the airflow on the dual Stromberg carburetors on my 68 Triumph TR250.
