I am in the middle of getting mine to run correctly, also. It is a new build, my first (a Black Stallion 66cc.) which looks great but has not been w/o problems. First the killswitch was faulty and prohibiting any chance of it starting (no spark), so I have removed the ground wire temporarily so I could get it running. Then, running, it would perform EXACTLY as you described. I am running a 16:1 ratio, also, and was scolded by my two-stroke guru buddy who said maybe I should siphon maybe a cup out of my tank and pour in some gas to even it out to closer to 18:1. I still have not done that as I found that, by taking off my float bowl, the little brass piece in there that looks like a pipe, was slightly clogged. Oh, hehe and it came from the factory that way AND was not even screwed in at all. It was laying horizontally on my float, AND my little white plastic donut float was 3/4 full of fuel???? Rule #1, if you buy something inexpensively, it doesn't mean it is going to be junk, it just means that it was produced inexpensively by cutting corners on material quality or cost of labor or just in not fully inspecting it before shipping. However, I have to say that the kit was complete, well designed, simple and included all the needed parts to make it fit nearly any oddball frame shape. It did not take me 3 hours as stated. More like 7 combined, and I still can't ride the darn thing. The guys at Kings were quick, courteous and immediately arranged that I will be getting a new float in the mail. I called on Tuesday at closing, so I figured they would process my request Wednesday and maybe mail it that day or Thursday. It is now Friday and the mailman has yet to arrive, so I am crossing my fingers that it will be in the mail today. It will take me 5 minutes to put it in the float bowl, screw two screws back in place, remount the carburetor on the silly little intake tube, pop my gas line back on and fire it up. I hope that works. Funny thing is while it ran like crap with a bad float and that brass piece not even screwed in, it still ran and actually pulled me up a pretty big hill. I am 210 pounds. I am not expecting a rocket, but if that is what it could do running poorly, I am certain to be pleased when broken in, dialed in, etc. Oh, btw, this is my first bike, a Schwinn Beach Cruiser. I have had it ten years for $199. The motor was about $175 including shipping to MO and then had my mother-in-law ship it to me in CA, where they can not sell them to CA residents. There are ways around that BS. I can hear about 50 different two-stroke weed-eaters, leaf-blowers and chain saws daily around here. Is it because mine has wheels and can potentially provide me with affordable transportation with a carbon footprint that is probably 1/5 of my 20mpg 4 cylinder Toyota?
