    I was wondering if the white float inside of carburetor bowl, when it becomes
    sinking from fuel inside it. Is this a common problem, and does a person have to keep
    extra white floats on hand all the time?

    It does seem to be a problem some have experienced. However it is clearly a defective float and it should never happen. Once you get a good one I doubt it will ever leak and fill with fuel.

    Thanks GhostO for the reply. I have your SBP standard shift kit that I
    ordered from you quite a while back. As soon as I gain a little more expierance
    with the HT engines troubles I will be putting it on a bicycle project. The white
    plastic float in the bowl lasted about 1 month running time in a CH80. I know it
    was not the dealer fault and will order another one from thats dax. I have order
    quite a few parts from you and Pablo.... and I am also waiting to try out that chrome
    expansion pipe that I recently ordered from you. I think your products are great.
    I know when I am done with the project bike it will be one sick bick.

    I have found that some factories never notice the seam in the floats when assembling
    if the seam is on the bottom, it WILL leak...much less rate of leaking when the seam is at the top
    after 2 bad ones, I started checking all of them
    the seam is approx 2/3 of the way along the outside ring of the float ( I think it was dax who clued me into even looking :))

    Thanks azbil, I first noticed a differance in the way the HT engine was running.
    I really didn't think much about it because I was running an oily -fuel for break-in.
    The engine had a smooth running sound and then it would kind of act like it was
    getting to much fuel and would effect the performance. I kind of think that they
    are alot more people out there that may not be aware of this until it is obvious
    that fuel is flowing out the carbureter. There easy to check, so I know what to
    check for this when I notice a running differance in my motor. Also to check for the
    seam up like you said. Great tip

    I recently had a simmilar experience,was running great and all of the sudden ....poop!...fart!----STALL!!.....I was thinking Fuel filter but thats not the fix.
    Right now shes not starting but seems to want to.
    tommarow I will check the carb and float,I had it flood a couple times before do you think it is as simple as the float?...im probably over thinking this again.
    how about a plugged exhaust?...I doubt it,fouled plug?....possible....SCRATCHING MY HEAD,OUT OF DAYLIGHT.

    Bad plug wire? Junk in the carb needle and seat? Lost connection in the wiring? If you have one of those Catalytic mufflers ya they can and do get plugged up. Moisture in the float bowl? Just trying to give you a few idea's. Intermittent problems are the worst. Still have good compression?

    I am going with what GhostO and azbil suggestions. I am going to
    check the plastic bowl for any signs of leakage and always make sure it
    is seam side up. Any signs of leaking I will replace until I do get a good
    one that does not leak. I just hope that I don't have to buy very many of
    them until I find a good one.

    I had one with fuel inside. Took couple months for it to dry out then I sealed the plastic seam with a soldering iron. OK for over a year now.

    I have a Skyhawk Gt-5 with the new style carburetor on it.
    I am waiting on a union gasket to mate it up with the carburetor
    and intake end pipe. I took the new pastic float out of it and put
    it in the CH80. I took it for a 3-mile ride this morning and the engine
    is running smooth. So I am back riding a happy time.
    I am going to hand drill a small hole in the old plastic float that
    has fuel inside it and put a firecracker wick inside the hole I drill
    and lite the wick. A china girl m-80....that out to be a bang.

    I just returned from an 8-mile happy time ride.
    The new plastic float in the carburetor bowl made
    the running of the happy time engine great. My
    carburetor jets were resized and by not having
    fuel inside the plastic bowl made the differance.
    So , yes something that simple did make the
    differance.

    I took the CH80 out for about 16 mile run this morning. It was chilly outside
    so I wore my heavy flanel shirt jacket. My carburetor is now tweek in, correct color
    to the sparkplug, good spark, good timing, cluth grips good. It is a smooth running
    engine that likes to rev at the crack of the throotle with no ugh-ugh sound. I noticed
    the gas milage is getting alot better. I am now ready to move on to the SBP shift kit.
    Sadly the CH80 will be coming off the bike, for me to install shiftkit. I will take my time
    doing this. The Skyhawk 66cc will go on the bike and I will break it in and tweek. I will
    have to make a choice between 2 bicycles for the SBP kit 1. Rear suspension beach cruiser
    or the maui downhill worksman. Which ever bike I find workable will have the nexus 8 speed
    shimano internal gear. I want to thank every one that shared their tips and thoughts with
    me and thanks. I am going to be very busy for a while.
