Title: Re: Trouble, maybe the carburetor? Post by verslagen1 on 07/30/14 at 14:47:43 29mm ? is that the float height? max had a collapsed float, which threw off his float level. If you have similar issues, check your float level. easy way is to attach a clear line to the bottom of the carb drain and open it. with prime on, the gas level should rise to just under the gasket. For reference (http://suzukisavage.com/cgi-bin/YaBB.pl?num=1364725734) |

Title: Re: Trouble, maybe the carburetor? Post by busne on 07/30/14 at 16:36:41 this is the situation -black\rich spark plug -bike run only 40\70km after this stop and don't start if i don't put in a new spark plug -I never use start choke for start the engine when is cold -the bike is original and all jet carburator are clean and original -float is not damage (I make a test in water) -vaacum line have not gas when the bike not run -if I run with on or reserve position in petcock without vaacum line the motor try tostop -if it's in prime without petcock...always run -today I make a test: the bike already run with air/gas mixture screw all closed!!! and I the engine don't stop!!! I think is not correct... question: how the vaacum line work when the engine run??? what kind of other test I can do? Is my problem a problem of rich gas/air mixture? my carburetor code: 24B40 E241 tell me some info of original jet measure thanks a lot!!! |

Title: Re: Trouble, maybe the carburetor? Post by Dave on 07/31/14 at 05:55:05 It sounds to me like you have a bad petcock, and it is letting fuel enter the engine through the vacuum line. Plug the vacuum line on both ends, set the petcock on PRIME, and ride it for a while and see if the bike runs correctly. If so....you need a Raptor petcock. Dave |

Title: Re: Trouble, maybe the carburetor? Post by busne on 07/31/14 at 07:53:15 ok dave...I make your test this evening...but tell me: -what's the difference from original petcock and a raptor petcock? -with the raptor petcock I have always to connect the vaacum line? -and in last...if you're right...why I don't see some gas come out of vaacum line when it is disconnected? thanks! |

The colortune would be just about worthless on the Savage.

The Raptor petcock is manually operated. You must turn it on by hand when you want to ride, and shut it off when you are done riding. There is no connection to the vacuum port with the Raptor, and you need to plug that port on the side of the carb to stop the air leak. Without the engine running - there is a spring that closes the diaphragm and stops the fuel flow....this spring will work even with a hole in the petcock diaphragm and will shut the fuel flow off. When the engine is running and pulls the diaphragm open - it can leak fuel into the vacuum line if the diaphragm is leaking. Dave |

Mostly, yes. But still leaves the possibility of... Quote:
In the early stages of diaphragm failure, the leak may only occur while running... vacuum assisted leak so to speak. and if you also have a leaky vac line, enough air can flow to clear any trace of gas. |

In the prime position the diaphragm is pushed open by a small piece of metal - so the fuel flows all the time....even if the engine is not running. In the FUEL and RES positions the fuel only flows when the engine is running and making a vacuum. And yes....the diaphragm can leak in PRIME, FUEL or RES if the diaphragm is going bad....unless you block of the vacuum line. Have you tried blocking off both sides of the vacuum hose yet, and then set the petcock to PRIME - and gone for a ride to see if the engine runs correctly yet? Dave |

Title: Re: Trouble, maybe the carburetor? Post by busne on 08/02/14 at 03:33:06 ...dave...after the ride with prime position must I control the spark plug?....and if the problem is the petcock in this way the plug should be ok... after my holiday I try this test!!! thanks guys!!! ;) |

It has airror at the end that can be adjusted to see the flame. When I set the MGs up I never drove them done the road either. But I could throttle the engine. Trying different setting on the carb works too although doing it while driving down the road isn't a good idea, I've spent too much time in hospitals lately. |

Title: Re: Trouble, maybe the carburetor? Post by busne on 08/30/14 at 02:09:57 HI guys!!!...I come back home after my Holiday... I immediately make the "WITHOUT vaacum petcock test" and the engine run ok!!! ...I think my petcock work bad in ON position.... >:( I have a question...in this condition is possible run Always with the vaacum pipe disconnected and closed and also the petcock Always in PRIME position? and when I stop the engine turn the petcock in ON or RES position... ;) waiting an answer...thanks!!! |

Title: Re: Trouble, maybe the carburetor? Post by Steve H on 08/30/14 at 03:45:14 You can ride with it set to prime always. You won't have a reserve fuel setting and will have to watch your fuel level carefully. As long as the bad diaphram doesn't get any worse, it should still stop fuel flow when the engine is off and you put it to on or res. But, you still have a bad petcock. It would worry me |

Hi Busne, sorry to be late in the discussion :( Anyway, Verslagen is right, my biggest problem was the float... it was beaten up pretty bad, so i guess the reduced volume of the float screwed up the level in the carb... I was lucky enough that as soon i changed the float and switched to a warmer spark plug the bike started to run properly. I will check if i can see your email or send you a PM with my email and phone, and a link to download the Clymer manual that i have found just today... If anyone else is interested let me know if i can post the link or, otherwise PM me... |
