How to tighten a chain on a 110 kazuma quad - Quad 47 cc / 49 cc Pocket Mini Bike Scooter Atv Pull Start

The best way is to twist the high speed screw in all the way (do NOT jamb it in - gently screw until it wants to stop), then back it out 1.75 revolutions. Start the motor, and run it under load. Stop, lean it out some by screwing in the mixture screw in 1/4 turn. Try it. If it gets better, repeat until it gets worse and then go back one step. That should be the setting. The same if you chose to richen the mixture by turning the mixture screw OUT 1/4 turn. Repeat and follow the above directions. Going one way or the other is a guess at first, and you hone in for the best performance. For the idle screw, just piddle with it until it sounds good at idle. You should start out at 1.5 turns from closed.
