  1. Must have for dual carbs 5 Star Review

    Posted by on 13th Jun 2016

    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.

  2. What can I say 5 Star Review

    Posted by on 1st May 2014

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

  3. good tool at a fair price 4 Star Review

    Posted by on 18th Jul 2012

    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.
