Uni-Syn Carburetor Synchronizer/Carb Synchronizing/Balancing Tool Weber Su Type

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!

Simple but effective.

but couldn't use to adj. my bike carbs so I gave it to a mechanic friend of mine.

The recommendations amazon suggested for this review were 'stretch', 'sheerness' and 'value for money'.Umm no sorry to disappoint it isnt stretchy or sheer. My legs couldn't handle it.This works perfectly. I tuned my carbs quickly and easily. My car is running beautifully after using this thing that is exactly what it is and does what it's supposed to do. No frills, no sweetness, and no stretch.

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.

Works like a charm. Easy to read and adjust. Product exceeds expectations

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.

I had to re-engineer this thing to be able to run the engine while getting a good read. Out of the box, adjusting to give a good read would kill the engine.
