| Post subject: | idle issue??? |
i have a 75 swinger with a super six setup and an open 6 to 1 header. i can't get this thing to idle. the only time i got it to idle was after the engine warmed up for a while from trying. then it idled. is the engine not idling because of the lack of back pressure or is there another possible reason? i don't plan to keep the exhaust open but i would like to have the car running properly wen i get the exhaust system next week. thanx in advance. |

sounds too lean, it might be less backpressure than stock sup 6 exhaust manifold so it needs a richer mix, how was it before the header? is there any smoke? |

for some reason my signature says super six but i am actually rolling a single barrel holley. i am although about a week away from getting a sup 6 setup thanks to another slanter. i have although done this with many other carbs, i am going by basics. get the car warm enogh to idle if you can try 1/2 turn counter clockwise each see if it ups the idle, if it lowers it go the other way. i use 1/2 turn increments some use 1/4. if your car is running good it might be your choke adjustment also, if your car idles good warm than it most likely is. I am sure the more experienced slant tuners have a good formula and some standard settings. the articles section of this forum is loaded with info, check it out |

That line under your member name (Super Six, Hyperpak, etc) changes with the number of posts. It's just one of the fun features of this forum, and I like it! Personally, I still have my BBS in place, although a BBD and its two-barrel manifold are waiting on the shelf. |

I couldn't get my slant to even stay running let alone decently idle with open clifford shorty headers. It took a number of starts to get it on the flat bed towtruck that took it to the exhaust shop. |

it idled fine after you got the exhaust? |

Affirmative. Without an exhaust, I would have to keep the pedal down or the motor would just die, and it was a pain to get it started. Once the exhaust was on, started on first crank with no pedal at all. |

| Post subject: | Choke? |
If you didn't connect the choke up correctly, you'd have a heck of a time getting it to idle cold, but it would run perfect when warmed up. Is the choke flap closed when cold starting? |

funny you mentioned that i installed a manual choke because theres was nowhere, to my knowledge, to bolt the automatic choke because of the header. |
