Title: might be your petcock even if vac line is 'dry' Post by furious70 on 07/09/09 at 13:06:47 Been fighting ridability problems with my wife's savage for 2 yrs off and on with it being fine one day (or hour) and pig rich the next. 2 different carbs on and off several times with various internal parts. Before I did any of that I, per advise on here, did check the petcock vac line, and it was always dry. I never thought to pull it off the instant it started acting up though..... Finally a friend suggested just trying it manual for awhile with the carb plugged and the line loose. Been running perfect for a month now, no issues at all, and a dry line. I don't really know what would cause intermittent failing of the petcock, as a tear in a diaphragm should always be a problem, but however it's screwed up it appears to have been the problem all along. Oh well, ended up with a spacer mod and the stock jet and it runs better than it ever has. |

Title: Re: might be your petcock even if vac line is 'dry Post by justin_o_guy2 on 07/10/09 at 03:50:40 A cracked or pinched vac line wouldnt make it rich. It would lose fuel, because the petcock diaphragm wouldnt get the vac needed to deliver fuel unless it was in the Prime position. Finding the problem in the petcock would be really good for everyone. Good test to "prove" the petcock, even tho it wasnt demonstrating that the problem was coming from the petcock. Thank you for the post. |

Title: Re: might be your petcock even if vac line is 'dry Post by furious70 on 07/10/09 at 06:33:25 Vac line is in good condition, but the above post is true about that anyway. another question, why is converting to a raptor petcock always suggested? The OEM one seems to work fine using the PRI side to run and turning it to on when shut off. Or when the petcock actually fails with fuel coming out the vac line does it leak through even when shut off and the line disconnected? |

Title: Re: might be your petcock even if vac line is 'dry Post by justin_o_guy2 on 07/10/09 at 06:35:54 One prob with running on prime is that IF you run out of gas, you are really, no kidding, OUT, no reserve.Far as I know, that is the only downside. |

Title: Re: might be your petcock even if vac line is 'dry Post by Serowbot on 07/10/09 at 11:02:21 When my petcock went bad, the problem was intermittent too. And there was no gas in the vacuum line,... until you sucked on it. Then the gas flowed. And that's what the engine does,... suck on it. So the real way to test it for sure is to suck. Then spit, don't swallow.... :-? I don't always mention it when I'm recommending testing, for several obvious reasons.... Let the puns begin!.... :D |

Title: Re: might be your petcock even if vac line is 'dry Post by MMRanch on 07/10/09 at 12:54:37 Just replaced mine with a raptor 350 (1/4" spacer needed) no vacume line and no problem. |

Where do you fit a 1/4" spacer? I got a Raptor petcock which I'll probably install tomorrow, but I thought it was a straight bolt-in replacement. |

Title: Re: might be your petcock even if vac line is 'dry Post by tomtaz1975 on 07/11/09 at 08:12:53 my understanding is a raptor 660 petcock is a direct replacement. I hope so, because that is what I got, just have to install it. |

Title: Re: might be your petcock even if vac line is 'dry Post by Boule’tard on 07/11/09 at 09:40:19 Oh. Raptor 350 vs. 660. <bonks forehead> We should be good with PN 5LP-24500-01 and no spacer. |

furi, I was running around like that with mine (see signature) for almost three years without any discernible problems. I'm switching to a Raptor petcock, however. My rationale is that I'm pretty sure the OEM petcock has a bad diaphragm in it. I cannot be sure the problem will not continue to get worse and progress to a situation where the petcock fails to the point where fuel can flow even when the engine is not running and the petcock is set to ON. Then, if I get a leaky needle valve in the carb, it's "flood city." You pays your pesos, you takes your chances. |
