The easiest air flow meter I have used so far. If you have dual carbs, you have to have this tool to get all performance out of a dual carb set up. I recommend this air flow meter as the one to buy.

Not much to say here, it works like its supposed to. It's well built and easy to use

I grew up tuning British cars and Corvairs with a Unisyn (made in UK). When the time came to get my own all I could find were copies made in China that don't work well at all. A friend had an old Holley tool that worked well....this is a copy of that tool. It works well, the adapters fit my Triumph and Corvair carbs and I had no trouble getting the carbs in sync. This is a good tool for the money.
