    After browsing through the threads throughout the site I came across one all about how to assemble a carburetor.

    .....then realized that I've been riding my bike the past few days entirely with the choke wide open. Thought never even crossed my mind since the bike has been performing well (or so I think).

    Did I do any harm? And, what difference am I going to notice after I put the choke in. I would try it myself right now but it's 1am and I don't want to wake the neighbors!:ride2:

    wide open refers to the throat of the carb, choke is the opposit. wide open lets it breathe.

    Choke on or "closed"- lever "UP".
    Choke off or "open"- lever "DOWN".

    Throttle open- slide in "up" position.
    Throttle closed- Slide in "down" position.

    I guess that makes sense. I'm surprised I never had any problems at all starting it, specially considering it's about 45 degrees here!

    starting is the ONE thing I've NOT had any trouble with on my motor bike
    I can roll down my driveway into the street and pop the clutch, even when it's the first time that day to get started, my bike fires right up.

    If it's 45 degrees F and you can start the bike with no choke, I will bet you are running very rich. Have a look at the plug, and if need be, move the clip up one notch.

    Fouled plug.
    Four stroking.
    Carbon build up.
    Rough running at cruise.
    Bad fuel mileage.

    Mine won't start up cold even here in S. Fl. without the choke closed. (usually 80 degrees). I used my old front de-railer control and cable. Fabbed it to the choke lever on the carb and with a return spring. I used a piece of copper tubing with a smaller piece soldered in the end, to hold the housing to the frame and direct it to the carb. Now I have a 3 position click de-railer to close the choke and gradually open it with 3 positions as the engine warms on the fly.:ride2:

    Four stroking is when the two stroke engine is so rich it chokes on it's own exhaust and intake mix and basicly fires every other revolution, like a four stroke.

    It is the sound your engine SHOULD make when very lightly loaded. As soon as you begin to crack the throttle and load the engine, it then should break back into a clean two stroke "buzz", not a four stroke "staccatto". If your engine takes a few seconds to "clean out" when you open the throttle, you are just a little too rich. If it never quits four stroking, well, you will know it.

    Thanks, very descriptive! That's kinda the idea I got but I knew you would explain it well. Never heard that in the m/c world.(^)
