Review on Stens 615 512 Carburetor Zama RB 54 by Zach Curd

The fuel system product we bought did not seem to deliver a performance upgrade to our Automotive car .Using this product, our team found that it didn't fit properly and caused leakages leading to incomplete combustion. The only pro was that the ordering process was hassle-free. The cons were many, as the product offered no improvement in engine EXHAUST gas emissions and no improvement in fuel consumption. We wouldn't recommend this fuel system product to any Automotive car enthusiasts..
