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

Simple but effective.

Good

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.

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

Too cheap. Such poor tooling and quality it would not work.

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.

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!

I knew I had to tune my engine and once I used this I found that I had my carbs way off. Now they are balanced and working as one together to produce more power over the entire power curve.
