G16 carb rebuild kit and fuel system diagram
I have a G16 that I want to refurb a bit. It is hard to start and only stays running if you feather the choke. I plan on cleaning the entire fuel system and would like to rebuild the carb. I can only seem to find the cheap replacement carbs but no rebuild kit. Also, There seems to be some missing hose from the air filter housing to some other device. Any help finding a fuel system diagram and rebuild kit for the carb appreciated. BTW, I have found and downloaded the owners manual but that doesn't have quite the detail I need.
Thanks |

Re: G16 carb rebuild kit and fuel system diagram
There should be a rubber hose running from the air filter housing to the valve (rocker) cover. It is not part of the fuel system but rather a crankcase ventilation.
The fuel system is rather simple. Fuel line from fuel tank to fuel pump. Then line from pump to carb. There is another rubber line from the engine port below the air filter housing that runs to the pump. It is a pulse line to run the pump. The pulse line does not flow fuel. The pulse (air) operates the diaphragm in the pump that in turn flows the fuel from the tank, through the pump and to the carb.. Sorry for sounding so basic but not sure of your understanding of the system. As far as a carb rebuild kit, I am not sure. You could always order one of the chinese carbs and use parts from it to rebuild your factory carb. If you are having to 'feather' the choke, it sounds as if your carb (likely the jet) has a restriction and is not flowing ample fuel causing a 'lean' condition. |

Re: G16 carb rebuild kit and fuel system diagram
Thanks, yeah it is the crankcase hose. I guess I will just pull the fuel system apart and do a deep clean. Maybe I don't need a rebuild kit. Just find it strange that I can find rebuild kits for other models but none for the G16.
Thanks again. |

Re: G16 carb rebuild kit and fuel system diagram
Not much to rebuild since these carbs don't really have an idle circuit. Quite simple, really. The only part you may need to replace is the bowl gaskets. Just clean it really well with carb cleaner and blow it out with compressed.air and you'll be fine.
Personally, I like to use an ultrasonic cleaner filled with carb cleaner, but that's only usually necessary if it's really nasty. |

Yamaha doesn't offer a "kit", each piece is sold individually.
