    Hi
    I confirmed yesterday that my china girl runs better when cold
    When hot starts to 4cycle at constant speed and lacks acceleration
    Needle clip is in the second notch from top, will try it in the first notch and post my results
    Peace

    Keep us posted.

    I had one kit where it ran too rich in the top position. I personally took the cheap route and opened up the air filter cover with some holes, and it was close. I removed the baffle and it ran perfect.

    You can buy a smaller jet too.

    Hi
    Needle clip is in the top notch
    Seems to run cleaner at cruise speed
    And seems to have a bit less acceleration
    A single circuit carb like our china girl has is a compromise
    I will start looking for options with more circuits
    Peace

    You know these things do a 2 cycle/4 cycle break at cruise when set up properly right?

    These carbs are primitive. Some solder the jet closed and re-drill it to the proper size. There is a thread or two around here about that.

    Hi
    Exactly
    Now it is kind of a 2-4 cycle when cruising
    And a bit less acceleration
    Most of my riding is at cruising speeds, so I think it is better now
    If I would climb long hills I would choose the previous setting
    I am sure there are scooter carbs with idle, transition and main circuits
    That would be perfect

    I will enjoy my mb for a while

    There are those that adapt Walbro carbs, check the search function for a whole bunch of stuff.
