Title: Carb valve stuck or normal? Post by Niallmac on 06/24/22 at 02:21:27 hi My LS 650 1994 won’t start after a break of about 8months. It Turns over There is spark Spark plug is dry There is fuel to carb from tank I’ve removed the air filter and tried to lift the throttle valve. It only moves about 5mm. It doesn’t move when the throttle is twisted. Should it? Cheers Niall |

Title: Re: Carb valve stuck or normal? Post by Gary_in_NJ on 06/24/22 at 03:53:08 Remove the carb and clean it. I don’t know your method for lifting the slide, but it should easily move. You’ll discover it’s condition when you clean the carb. If the slide has corrosion, it will need to be replaced. Or maybe you bent the needle trying you lift the slide with too much side force. |

Title: Re: Carb valve stuck or normal? Post by Niallmac on 06/24/22 at 04:00:18 Thanks Gary I’ve ordered a rebuild kit but was just wondering while I wait before stripping the carb. Im just lifting with my finger through the inlet. No pressure applied. Anyway, from what you say, she should move so I’ll wait until I get into it. |

The slide does not move when the throttle is twisted, it responses to air flow. When the throttle is twisted, a butterfly valve moves. A stuck slide will not keep it from starting, it just won't go anywhere. Some countries have a spacer above the slide for learners to limit slide travel. Your carb is probably gummed up from sitting. Clean it. |

Title: Re: Carb valve stuck or normal? Post by Niallmac on 06/24/22 at 08:49:24 I’ve started cleaning (float was definitely sticking too). Out of interest, how much movement would you expect in the slider? 10mm? 5? |

by your finger, it will move the entire opening. |

Title: Re: Carb valve stuck or normal? Post by Niallmac on 06/24/22 at 09:20:22 Ok thanks. It moves about 5-10mm. I’ll start looking there then |

Title: Re: Carb valve stuck or normal? Post by justin_o_guy2 on 06/24/22 at 09:47:04 I'm sold on using a whiff of ether on starting anything that has been sitting. Saves the battery and starter motor and helps troubleshooting. |

Success! It’s freed up. Possibly from leaving for the carb cleaner to get there. The needle has a 3mm wide circle of a glue like film that stopped it lifting. A bit more cleaning and she should start. Thanks for all your help! |

Title: Re: Carb valve stuck or normal? Post by Niallmac on 06/25/22 at 09:08:54 Next step I’m afraid. After cleaning, it turns out that the float bowl is not filling at all. I’ve removed the floats and the pin in the picture moves as expected. I’ve also blown compressed air down inlet. Do I need to remove the piece arrowed? If so, how does it come out please? |

Title: Re: Carb valve stuck or normal? Post by Gary_in_NJ on 06/25/22 at 14:30:17 There’s your problem. That rubber piece should be soft, pliable and pointed. Your looks like 3-strikes, so it’s out. Before you reinstall the new float valve, polish the seat with metal cleaner and a q-tip, and also replace the o-ring. |

Title: Re: Carb valve stuck or normal? Post by Niallmac on 06/25/22 at 14:45:56 Hi Gary Which rubber piece do you mean? The gauze end with the white plastic? That plastic was inside and I pulled it out to get to the gunge. I ordered a repair kit last week as I knew I’d need a gasket at least. It looks like it comes with a valve and seat. However it looks very different to what I’ve just removed: https://www.ebay.co.uk/itm/313469328804?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=0gi-c_zstjy&sssrc=2349624&ssuid=gghISK98SsO&var=&widget_ver=artemis&media=COPY Will that be ok do you think? It’s supposed to be for all LS650s |

Title: Re: Carb valve stuck or normal? Post by Niallmac on 06/25/22 at 16:07:12 Will this replace the one in my photo? |

Title: Re: Carb valve stuck or normal? Post by DragBikeMike on 06/26/22 at 11:53:19 Niallmac, IMO the seat in the repair kit photo looks the same as the seat in your photo. I think if you removed the needle valve and the inlet screen from the assembly in your photo, you will see that the two look the same. The repair kits are tricky. There are a lot of posts on this forum reporting less than stellar results from repair kits purchased on eBay, Amazon, etc. Although the genuine Suzuki parts are astronomically expensive, they seem to be your best bet for success. This post should prove useful. It will tell you what to look for regarding the repair kits. It's not all-inclusive, but it will get you headed in the right direction. I can tell you that the seat I received in the "All About Carbs" kit is dimensionally identical to the illustration you provided. Only thing I can't verify is the diameter of the feed hole in your seat. BTW, the "All About Carbs" kit was totally bogus junk. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1641171298 You reported that your slide needle was stuck in the needle jet. You stated that the needle had "a 3mm wide circle of glue-like film". Based on your video, it looks to me like the needle was indeed glued to the needle jet. That most certainly indicates that your needle jet is fouled with fuel deposits. There are eight small emulsions holes in the needle jet, and I suspect yours are all plugged with goo. Can you remove your needle jet and post a photo? Cleaning the needle jet is difficult. Almost nothing cuts these fuel deposits. Mechanical cleaning is risky. The .121" hole (orifice) through the center of the needle jet is critical to correct performance. Cleaning it with any sort of abrasive is risky. The needle jets come in .0002" increments (that's .005mm). It's easy to ruin the jet with abrassive cleaning implements. I have found that PineSol will soften the stuff but doesn't dissolve it. If you soak it in PineSol for a few days you might be able to then scrub it out with a soft implement (like a Q-Tip or a small nylon brush). Post some more pics so we can see what you are wrestling with. Good luck. |

Title: Re: Carb valve stuck or normal? Post by Niallmac on 06/26/22 at 13:06:55 Thanks Mike. Great info on your post link. I’ll see what happens when the kit comes. It looks like I’ll need to wait for a new screen too. Do they come off easily? |

Title: Re: Carb valve stuck or normal? Post by Niallmac on 06/27/22 at 07:20:47 I only had the kit above and all fits and the bike is now running well! Great help all! Niall |
