Well said Bugs Bunny guy.  Haha.. am I the only one who has called him that? I thought someone else would have called him that before... anyway, do I need to buy the gap tool to do the valves? Is there another way? Thanks.. This question is for the bugs bunny guy too.. not only you  |

Oh it's too late.....you're part of this now. You'll get it fixed and then say "well that was cheap". And then you'll ride a while and think it's cool. We've all been there, there's no turning back, there is no escape now. Ah HA HA HA HA HA!!!   Ok, I have a spark.. now why isn't my damn scooter starting! |

I think you are still too lean, follow Alleyoop 4TS Carb Tuning Guide all the way through, including the driving tests where you let off the throttle and adjust based on the response. Be sure to give the engine a full minute and a twist on the throttle after each adjustment to let it get used to the new setting. Note- Do this after setting your valves, or you will have to adjust again based on the changes in valve duration. Before I do the lean stuff. I first need to fix the spark. Then adjust the valves, then I can do the rest. Never again chinese, never again! As soon as this is fixed I'm selling it. |

Alley was talking about the air intake going into the carb. He wanted to see if your mixture was getting too much air. The fan is on the right side of the engine. Your symptoms are typically maladjusted valves. Set them at .004" intake and .005" exhaust. There are tutorials under engine in the library. Now, if you are actually loosing spark after running a while it is probably the pulse coil on the stator. There's tutorials under electricity in the Library. The other things that come to mind are the ignition coil and the CDI. Electricals tend to fail after a bit of use when they heat up. I just changed the CDI and coil, I'll look at how to do the valves.. |

Set your valves before you do anything else. What is the cloth to fan gambit? The bug's bunny guy told me to do it and it worked (read earlier posts). I just checked and I lost my spark, I have a spark, it starts, five minutes pass and no spark. I swear this is pissing me off! |

If it dies and or wants to die AFTER the motor is nice and hot Then the problem is your Valves are tight and need to be adjusted. What is happening is your valves are not closing completely and the motor is loosing compression and will not hold low RPMS and that is why it dies. But If you want to try setting the idle a little higher here is where the IDLE SPEED SCREW is on your carb: Turning it CLOCKWISE raises the IDLE and COUNTER CLOCKWISE LOWERS THE IDLE. Alleyoop  I went to go do this, and had all my tools ready.. I wanted to start the scooter before I did this, and it didn't start. I feel like I am full of bad luck. I tried to do the cloth to fan thing and it didn't work. |

Nah, if it got too hot it would have started chuffing and loosing power. Once you get it dialed in you could check your compression and make sure you didn't hurt the valves for your own peace of mind. My other problem (that I can live with) is that the scooter dies at an idle.. I would start it (which takes a little work) then I would drive and if I get to a stop I always rev a little it while braking because I'm scared of it turning off.. someone said something about an idle screw when I googled the issue... I dont know what or where that is. Help? |

I have unscrewed the screw a little and I can't really tell a difference, it's still hard to start first time, but I think it should be fine. |

You beat me to it Jerry, I was just going to say that he is running lean and also probably loosing some power to boot. Also hard starting wears out the battery and starter. Alleyoop Okay. Thanks. It seems simple.. just turn the screw shown on the diagram. I did however drive the scooter for a total of 40+ minutes while it was lean.. should that be a big problem? I will do the fuel thing today. I haven't driven the scooter since Friday. |

Once I did the cloth trick, it started up and every time after that starts up fine, just over night it doesn't start.. SOMETIMES, if I do the cloth trick once in a while, without doing the card tuning, will that mess anything up? It drives fine. |

Cover the Air Filter to cut off the air try that. If it has a air box cover the AIR INLET to the box with a piece of rag or if you can reach it with your hand. Wow, never would have though of that... it started as it usually does. Is there a perminent fix for that? |

It should start on EITHER the 1st SHORT hit or 2nd SHORT hit of the start button. IF you have to keep on cranking it for it to start then it is NOT ADJUSTED RIGHT and NOT getting enough gas, that is why it takes a lot of cranking for it to fire. Alleyoop I have a new issue and need help asap. I tested and I have a spark but it won't start, worked great last night, but now this morning its tries but won't go. Please help, thanks. |

All fixed with a new stator, but it takes a long time to get started for the first time, then after I ride a bit, and stop it, it starts fine. Great, the cold hard starting is just a fuel and air mixture not right. So adjust the carbs Fuel Ratio Mixture to get the HIGHEST idle AFTER it is WARM you may be running a little lean or rich and for cold starts the motors are picky. Alleyoop Thanks, I will do that, but latley it's been starting a bit faster, the first couple times after I fixed the spark it was like a 40 second to a minute start, now its like 20 seconds sometime 30. |

Well here is what you should check if you wiggle some wires and it fires. 1. You have TWO wires coming from the stator ONE is the POWER WIRE goes to the BOTTOM SLOT on the TWO PLUG on the CDI. The Other wire is coming from the PICK UP COIL plugged in to the TOP LEFT of the 4 PLUG. Then You have OUTPUT to the COIL WIRE on the TOP RIGHT on the 4 plug and the bottom on the 4 plug is GROUND. 2. Then you have TWO wires going to the COIL, one from the CDI and the other is the GROUND. So check those wires and connections also check the wires on the plugs that plug into the CDI many times people grab the wires to UNPLUG it from the CDI and pull out the connectors so that when you plug it into the cdi they do not make good contact. Other than that that is your FLOW of WIRES 2 from the STATOR SIDE and one From the CDI to the COIL. Alleyoop  Thanks! I did this test yesterday.. but for some reason thought it was not the stator. After more tests and comparing to the 2010 model (that does spark) I'm pretty sure it IS the stator. I need help finding the right stator though. Hope someone can help. Thanks. |
