    I have a 6.5 HP 196cc Coleman ct200u, and I have no idea how to adjust the idle.

    I've been having a few problems on my bike, (backfiring, stalling with throttle, excessively long warm up time, backfiring on deceleration, running better with the choke on, sloppy idle) and I think most of them can be attributed to my engine running too lean

    I cannot find a fuel screw anywhere, and i have yet to take the carb apart, because I don't want to unless I need to (inexperienced). I have heard that the engine is very common and goes by other names, such as the Honda Clone, (and maybe a B&S, not sure) so there has to be someone who's run into this before

    Is there another way to increase fuel flow? Am I wrong about everything?
    I am new to this so any help is appreciated, thank you

    Hey bud,

    Easiest way for us to help you is to grab a couple of pics and post them up.

    Will point you in the right direction then.

    Sounds to me that the needle needs to move up a clip (if it has some) adjusting the idle screw is only for that idle mixture
    Raising the needle will richen up the mix right through the whole rev range but ti do that you will have to remove the screw cap on the top of the carb where the throttle cable goes in
    If u get stuck take some pics and we can walk u through it
