When I swaped the spark plug, I noticed the amount of fuel in fuel filter. Maybe the fuel don't pass to the cylinder from the carb. If I have time to work on my scoot, then I will check the carb. Right now my 2 weeks free time from work is over and begins the rough time of work.

Alright, now try different throttle positions when starting. Try restricting airflow (covering the airbox inlet) or allowing more (removing the airbox) to see if that gets it. Try adding a few drops of gas in the cylinder or even spraying carb cleaner through the carb or an unlit propane torch in the airbox inlet so it has some fuel for sure and then see if it starts. While I messed with the spark check, I tried some throttle positions - on full throttle, it almost started with 1000rpm. Next 4 things out of 6 I will check, when I have free time. Will Check:1. Restricting airflow (covering the airbox inlet), 2. Allowing more airflow (removing the airbox), 3. Spraying carb cleaner through the carb, 4. Swap the Naraku Carb back to old Carb. ( Last hope, when 1-3 would not help) Do not Check:5. Use an unlit propane torch in the airbox inlet ( I DO NOT HAVE THAT) 6. Adding a few drops of gas in the cylinder - maybe! ( through the spark plug hole  ) The 5th and 6th thing I will check when the 1-4 checkpoints do not help. Meanwhile I have to use public transport, to get to work and home  |

You can make your own propane torch simply and affordably, less than $15. At a hardware store usually in the plumbing or the tool section, you can find small propane cylinders and little torch heads that screw right on. Cheap and easy introduction to the world of torches.

( through the spark plug hole ) You don't need to try every fuel source. Whichever one you have that's easiest for you will work. Just looking to find out if the engine will fire with a fuel added. If it does, then you know you have a lack or fuel or some sort of mixture issue. |

Hey, 90GTVert . The user Hamsun did watch my spark test video and said , that the spark is wrong and I should look over my scoots electrical system. Is he right? I think, first thing I will do, is swap carburetor back to old one, then I will know if the problem is carb related. MY THEORY: The air filter extension, that I used (on the pic down below), I found several holes on that extension, when I swaped back to original airbox. Then I realized, that, mayby, when I drove on that rainy day, the mud got to the carb and closed the jets, so now the fuel can´t get to the engine, to start the engine.  |

Hey, 90GTVert . Today I swaped the carb back to old one, but the scoot still did not start. I´m out of ideas. I noticed, with the new carb, that the air box connection was wet. There was a fuel smell. If the spark is inconsistent, then what could be the problem. CDI? |

In the video of the spark check, I think it's alright. Parts of your ride vid seem like it could be an ignition issue, but I'd think it may be moisture related. My first scooter had iggy issues in the rain and it would sputter and stumble because of it, but it did it much more obviously than anything I see in your vid. As long as it's producing a bright spark at this point for the no-start issue I think I'd look elsewhere.
If there's much fuel around the airbox, then maybe the float height is too high or possibly there's an issue with the intake valve sealing or it's timing. If compression is up to spec, that should eliminate any major valve issue.

If compression is up to spec, that should eliminate any major valve issue. Today I brought replacement CDI and a tool, to get the Flywheel off. One customer sayd to my problem, that maybe the stator needs cleaning and then it will give more voltage to ignition.  I think, I will try that. Maybe I need to adjust the valves. I do not remember, what has to be the measurement. |

Well, 90GTVert . Yesterday I went to the StarMoto Shop and brought new CDI, but I did not use that. Brought these things too:   Then I locked the variator with a proper tool, took the flywheel plastic cover off and then removed the magneto-fan combo. Used the removal tool, that I yesterday brought. Then I took carb cleaner and cleaned the stator and then magneto. The Magneto was "SO" dirty. After that I placed everything where the used to be and installed fully charged battery. After few tries - The scoot started right up. Now I will swap back to the Naraku Carb and try again. I´m 98% sure, that the problem is fixed. |

Today I swapped back to Naraku Carb and before installing it, I took out the Carb´s metal cover shity skews and replaced these with stainless steel bolts. Looks like the user hamsun was right, when he told me to check the electrical system. Problem was magneto, it was very dirty, so the ignition coil did not get enough voltage to spark right. Thx. |

Today I noticed, that the horn does not work and the leht turn signal does not stay in. I went to the StarMoto Shop and got new left and right controls + Polini Kevlar belt. Swapped out the left controls and when I connected the wires, I noticed, the the horn wires where not bluged  . When I turned in the left mirror + adapter, the adapter bolt snapped. I think I will buy the grip mounted mirrors instead, because I can´t get the broken bolt out of the mirror blug hole. Or think some better solution to my mirror problem.  When I was in the Shop, the nice and beautiful woman, who takes orders, saw me and gave me my new battery, starter motor and rear undertail small plastic, that where arrived, to me. I was so happy. She said, that the left and right back bottom plastics and the battery charger are coming. |

When I left the StarMoto shop the day before yesterday, I noticed my scoot odometer (4100,0 km):  Yesterday, after work, I went to workshop on my work place. With a local toolman we made new threads to the mirrors. The original threads where M10, we went from that to M8. Some of the M10 threads we left alone for the nut, that secures the mirror. After that I installed both newly threaded mirrors and the new switch control to the right side too. Second thing I did, was swapping the Naraku belt to Polini Kevlar Belt. I did mess with all of that about 4,5 hours. The original wires for the right side controls wher 2 times longer then the new ones. I made an extention t the front low and high beam, so when I turn while riding, the motion of steerig does not brake my wires. Now works the brake light too, when I use the rear brake. Only thing that does not work, with the new controls is the parking small light on front the scoot. But that small ting does not disturb me at all. Some time I will bypass the wires some way, to make that light working again. Now some pics from the Naraku belt (maybe I made right desition, when I changed the belt):     |

Hey, 90GTVert . The "nice" weather @ Estonia Today - So much about scooting for few days  NICE WEATHER on 29.04.2017 is @ 14 min 02 sec. Before that 13 min 55 sec to 14 min 02 sec you can see the weather on that morning, before so called AWSOME weather. Time stamps are in video description too. |

Today I took time and made extension for the new right handle bar controls, because the new wireharness for the controls was shorter, than the original. I took the old harness and plugged wire by wire to the new harness. Found out the reason, why my parking light is not working, while making the extension. There was no wire soldered to the controls  I need to fix that some time @ the future.   |
