Cleaning up my garage and found this from back in the day.
Anyone else still have one of these? Hint: you wouldn't need it for any FJ series.

I used one on my 1979 MGB to sync the carbs

For balancing twin SU carbs. I still have one from my POS Triumph Spitfire that spun a bearing in El Segundo on a Sunday night and cost me $110 to have towed home, in 1983. Not that I remember specifics.

I used mine on early 70's BMW 6 cyl's. 2800CS, Bavaria, etc. I bought the Bavaria in a salvage yard after an engine fire. A couple of years later I'm driving down the highway and I've got a major loss of power but the engine is still running. Long story short, the needle/float valve on one carbs stuck open and was spilling gas out onto the exhaust manifold. Of course, I'm picturing another engine fire...but once the fuel evaporated, a hammer to the side of the carb freed the float and the trip continued without problem. This tool was used to balance air flow so that the front 3 and rear 3 cylinders got the same amount of air/fuel mixture.

I had one many years ago to balance multiple motorcycle carbs. I also used it on my 1967 Datsun Roadster with the Japanese version of twin SU's. Very handy tool, though I haven't seen it in years. Probably buried somewhere out in my "shop".

The proper name for it is a manometer.

The commercial name was "Unisyn".

They're still made (in China, of course) without the original name. I think Empi markets the thing for about $10.

They work but the block airflow. Better and quicker to use the more expensive 'snail' type - Snail Type Syncrometer Carb Sync Tool, GERMAN, SK Model - Aircooled.Net VW Parts but with some carb installs being able to angle the unisyn into tight spots is nice.

Thanks for jogging my memory. I couldn't remember what it was called. I haven't worked on a motorcycle, or any multi-carb set ups since probably the early 80's.
