Review on Motorcycle Mixture Keenso Carburetor Adjuster Motorcycle & Powersports by Nate Jenkins

When I unpacked the mixture screw it seemed fine to me at first then I noticed the o-ring was broken no big deal I had to replace it trying to install it then die Mixture screw, the spring was too hard and long to work smoothly and properly so I cut about 2 turns off the spring to make it work. My fingers got cut trying to install sharp edges, VERY SHARP EDGES. I ended up just using the spring and washer from that kit with my old mixer screw and tossing the rest in the trash. Looks good but doesn't work well. I do NOT recommend.
