Ok, I just opened the carb,
the needle is non-adjustable. But even if it was, I would be able to do the same, by tensioning the cable a bit through the adjuster near the handle/lever.
When I start the engine, with open throttle, the starter seems to be able to rotate faster, but it does not start.
Same with throttle closed.

The funny thing was, that I got it to start, but after running for a few minutes, it died, and doesn't want to start anymore. The exhaust does not smell to gasoline, The plug is foul (black) from the choke I believe and when taking out the spark plug I don't notice any gasoline in the mixture, and I can't smell it coming from the open spark plug hole (where I removed the spark plug to test compression, which I have. The carb bowl gets filled with gasoline after starting a few times (is that ok?) The company told me to put something in the air filter, to initiate better startup. Don't know what they told me to put in there. Why would it work, halfway riding 0.5 miles, and die on me; not start, when I drain the carb bowl, and try starting on a cold engine, starts for a sec, then dies, and remains dead? I tried starting again on a cold engine but the battery is empty now from starting (is charging). Some things don't make a lot of sense to me. There might be a possibility that the jets haven't been adjusted, as this is a 127cc engine, not a 125 (and the carb might be tuned for a 125cc?). I don't know if it's a mikuni carb, as I don't have a tube on the top, but the needle with cable goes in there. The carb is in a hard to reach position, not much I can show you as my cam can't reach there. but this is what I have:   and behind the watch:   I have a premonition, that it might have to do with the fuel supply. I connected the fuel supply (after fuel filter) straight to the carb. It might need to pass via the petcock; but I don't see where I could connect it to the petcock. There are 2 hoses from the carburetor (with at least one of them a vacuum line) going to a black box, which I can barely show here:  The black thing is behind the left top screw, behind the frame. I don't know what it is? |

Other countries other laws.
In USA it would be a felony, if not a serious crime to leave the place of an accident.

Is that the running or idle mixture that enriches when resetting the clip? Because it doesn't start, so idle mixture may be off. Here's a pic of the needle before installing:  |

Well, basically, until I figured out everything, I can't make a review. At this point in time the bike is about to return to the store. I got it running for about 0.5 mile, and it shut down on me in the middle of the road. I'd admit, if it would run, it would be an excellent bike. As for images, imageshack does not allow me to share the folder, and it has organized the bike pics not via file name or date. So it takes sorting out, however I can share all pics I've ever put on the web. Here's my imageshack account link: imageshack.us/user/prodigitUnder that link you'll see the Roketa pics first, and others after that too. The pics are usually of parts of a motorcycle I either want to address, or if there's a watch next to it, to indicate what I did around what time. |

I got no specifics on that bike, but in general terms, TaoTao's work quite fine and problemless for the first 500 miles or so. Make sure you inspect them, do a PDI.
Once a good PDI is done, no reason why it shouldn't last you a long time.
But the 150cc engines of TaoTao usually are quite complex; with a lot of vacuum lines fuel lines, drain lines, lots of electric cabling etc all over the place. So if something goes wrong, it may be much harder to pinpoint.
To me it looks like a cheaper mix between the ATM, EVO, and VIP (powermax) scooters they sell.

The carburetor somewhat looks like this:  Except on the top there's a steel throttle cable, not a hose. (like the throttle cable is directly connected to the needle) It has a choke, so I suspect it does not have an auto enricher? |

In FL, there's no insurance necessary, as long as you're riding with a helmet. Not even for motorcycles. The only bikers exempt from wearing a helmet are those who have personal insurance, or the ones riding a <50cc scooter or moped. We in FL are probably the last state where mankind still is truly free. Hi Its not the helmet, its being financially responsible in case you do have an accident Do you even know your own states laws? www.dmv.org/fl-florida/insurance/motorcycle-insurance-minimum-requirements.phpI would much rather pay an insurance company and let them deal with the repercussions of an accident then have to pay out of my own pocket Take care and ride safely dear friend Yours Hank For <300cc scooters it's about $80/yr basic coverage, 120/yr for upto $10k collateral damage, and $15k bodily harm (or something). They're clever, because in most cases there's very little harm in scooter accidents. In case someone else hits me, I'm covered by the uninsured motorist coverage (as long as I am wearing my helmet on my >49cc motorvehicles. |

That's more for impurities, not because the oil is wearing out. The smaller the engine size, the less the efficiency, the more impurities. |

Ok, at first sight there does not seem to be any vacuum leak. All hoses are connected, they're new, undamaged.
I unplugged the fuel hose, and fuel came streaming out.
I opened the carb drain screw and a lot of fuel came out.
I closed and opened the fuelvalve, got everything together again, took out the spark plug (somewhat black, can't blame it, I've been starting for the past 6 hours or so), there's compression, but no fuel damp.
Closed the spark plug, surprisingly the motor started, but only with the choke in open position.
Bogs down when I close it.
I adjusted the idle to very high (like 2k rpm), and choke open. It still died after about 15-20 seconds of barely staying alive. The carb drain was full of gasoline again.
Funny thing is that it started when cold...

Since your scoot is a 50cc, I'd recommend the most liquid gear oil which will be as hank says, or get the standard 80w90 oil.
Some users use 75W140, but that oil is a bit thicker. Good if you want to extend gear life, usually for more powerful machines (like 150+cc), or if you really don't need to go beyond 35MPH anyway on your 50cc.

The temp differences between hot outside temps, and cold temps, are only minimal in an engine block. Thicker oils are used on older engines, to get better compression on piston rings that don't seal well anymore, etc...

Best thing I'd advise, is get a GPS, ride at a constant speed (eg:30MPH on GPS), and look where the needle points. Then do the same for 40, 50, 60 MPH etc..
Once you know where the needle points at which GPS speeds, you can use a permanent marker, and just add dots and MPH numbers on the plastic.
