Review on 67256 Polished Aluminum Secondary Carburetor by Gary Revils

Perfectly launched, straight out of the box. Mine only needed minor adjustments. The only odd thing about this order is the label on the box with the number 650 instead of the 670 ordered. However, this one has an idle adjustment on four corners and was $200 less than the main brand. Even if it's 20 CFM less, my engine doesn't seem to care.
