He's not getting gas to the carb, you're right Raford63, it might be a vac problem not opening the petcock. By the way Hebert, if your carb diaphragm doesn't have rips or tears it should be OK.
Hebert, here's a setup on a scooter that I think is just about like yours:
Try this hebert:
If gas came out either that fuel line is plugged to the carb or maybe your float valve is stuck.
If gas didn't come out when you cranked it do the following: unhook the vac line (blue) at the plastic "T" and gently suck on it. If gas doesn't come out either your petcock/fuel valve is bad, you're not getting enough vacuum on the valve, or the gas line is plugged from the tank to the valve. Rich thanks tomorrow try again... |

Take the hose off the carburetor and verify flow when you attempt a start. I have already done and out fuel when I try to start ... the diaphragm is working fine but I find it very thin be the cause? thanks. |

La manguera del crankcase breather no mas sirve por dejar escapar el pression que sube con el compression del piston. Tambien sale aceite vaporizada, y por eso debe ser connectada normalmente al airbox, que tambien debe tener un tubo de salida por el aceite que se agarre. En veces no mas tiene una manguera colgando solo, pero esta manera es muy sucio por todo el aceite que sale. Es muy importante de mantener la manguera abierta por que sale el pression o se puede romper una gasketa. Entonces, deja colgando el fuel drain y el crankcase breather por que no son causa de problema. claro en mi atv no hay nada para conectarla con el airbox asi que la dejare colgando sola, el diafragma del carburador trabaja bien a simple vista cuando coloco mi dedo hacia dentro del carburador lo puedo hacer trabajar subiendolo, pero esta muy delgado podria ser la causa??? muchas gracias |

One vac nipple on the intake manifold is not unusual, all the vacs run off of it. Sprocket is right, that's a vacuum fuel valve/petcock, not a fuel pump. It does appear to be hooked up right but it looks like there's a kink in the fuel line. Rich moved the tank to take the picture why the line is crooked but for the photo |

No se connecta la manguera fuel drain a nada, no mas la deja colgando. Solamente sirve cuando se esta vasiando el fuel bowl. Pero la crank case breather se connecta al air box (filtro). Que no hay un lugar sin tubo alli? Si esta abierto alguna connection por el vac line, chupa mucho aire, y no corre el motor, no mas chupa aire. En el techo del carb hay un diaphramo de gommo, si esta torzido o ojerado no se levanta cuando se avanzamas resio. I reiterated what raford said to just let the drain hose hang, and asked if there isn't a spot on the airbox to put the vent hose, and a loose vac line will suck too much air to run the engine And to check the rubber diaphragm in the top of the carb for tears or leaks. Sorry for my Spanish and English do not ask for forgiveness and thank you very much for your help no man no hay ningun tubo sin coneccion pero hay una manguera en la parte trasera no se donde va la crankcase breather... |

Well hello Hebert, glad to have you on Scooter Doc forum. Yes we have a bit of a language barrier but this won't be the first time. I'll just put a few things out there and hopefully I'll touch on what your problem is. First of all, this is your crankcase breather:
It usually runs up to a connection on the airbox or sometimes is just tied off on a frame member with a filter on it. I hope I'm wrong on what I think you might be saying but the crankcase breather should NOT be connected to the carb drain hose in any way. If you did have them somehow connected drain all of your oil and replace with new. Do NOT connect the crankcase breather and the carb drain together!
Now, there's a drain hose that comes off of the carb float bowl, I think we're in agreement on that. Sometimes there's a screw on the carb that you must turn to let the gas out as you see on the left carb:
Sometimes there is no drain screw on the carb and it is at the bottom of the drain hose:
These must be closed or the gas will drain out of the float bowl and your engine will stop. So make sure your drain line is not plugged into the crankcase breather and make sure that the drain line is not losing gas by checking the screws. If this is not your problem let us know. Rich which connect the tube drain carb? that was connected to the crankcase breather my bike does not start  |

La mangera crankcase debe ser connectada con el airbox. Si se abre la fuel drain y corre bien el motor, pueda que el float valvula esta apretada en mala posicion, y se deja corriendo el gas hasta que se enfloje(?) el motor. Al mejor, explicame lo que esta pasando de una vez en Espanol por que no estoy seguro que pasa. en español es mejor para mi... lo que ocurre mi moto no parte, cuando saco el filtro de aire y coloco mi mano en la entrada del aire quiere partir y lo hace pero al acelerar se apaga. lo que explique en ingles es que ayer logre hacerla andar pero primero salia combustible (gas) por la manquera de rebalse (la que se encuentra sin conectar a nada y esta en la parte superior) logre que dejara de salir combustible cerrando el tornillo que se encuentra en la parte baja del carburador (float bowl drain screw ) pero luego de esto la manguera (float bowl drain line) que va conectada con la manguera (cranckcase) se sale de la union ya que el aire que ingresa a la manguera no tiene por donde pasar, si abro el tornillo de float bowl pierde combustible por la linea de float bowl line ayer deje que funcionara con la manguera de crankcase desconectada y andaba bien pero al acelerar se detuvo y no pude hacer que andubiera mas hoy probe y nada no anda que puedo tener malo? gracias por sus repuestas |
