About Racing Carburetor 2 Stroke 49cc 66cc 70cc 80cc With
High Performance Carburetor drastically increases airflow and fuel delivery resulting in more power. This power translates into a huge increase in torque and acceleration and resulting in an overall better performing engine. Specification: Material: aluminum Color: Red, Blue Size: 113*89*100mm Install: Unscrew from back of carburetor where it attaches to intake manifold remove the old one put the throttle cable on the new one you may have to use the old cable sleeve adjuster I had to on mine slide the new carburetor on the intake manifold tighten the screw down and you should b good to go Package included 1 x Racing carburetor 1 x air filter About The Jet: Start with the smallest size jet and give the bike a ride at full throttle for a few minutes. Remove the spark plug and observe the color. It will likely be a bright white indicating a lean mixture. If its a carmel color, then you're golden! No more adjustment needed, otherwise, drain the float bowl, disassemble, and increase the jet size by .01mm. Repeat until spark plug looks ideal. Your motor will run the most fuel efficient like this and the engine will run smoothly. Note: Do not turn your screwdriver all that much harder than you'd twist your throttle. If the jet feels tight when it's first going in, it's probably cross threaded. Back it all of the way out and try again.
