Just wanted to get an idea of where your settings are for those of you with a 500avs. Mine as of now is: primary - base secondary- base needle- .068 x .052 spring- pink acc pump- middle My timing is 16* init + 16* mech with no vac on Mallory diz. 268 cam .016in .018ex |

I'm running an Edelbrock performer 1404, but they should be close if not the same Carb. Primary - base Secondaries - 1 step up Needles - Base Accelerator - outer hole Orange springs Timing 18* initial, 9* mechanical (I believe), not sure on the vacuum. Still have to map it. But she runs great! |

My 500avs is setup like this: primary: 3 steps richer secondary: 2 steps richer step up spring: 7.5hg needles: base accelerator pump: base secondary valve spring: 3 full turns past no resistance Ignition setup: initial: 10* BTDC total: 31.5* all in at 3000 rpms vacuum advance hooked up and setup to eliminate surging. The car runs great, best time of 8.31 in the 1/8 mile and 20mpg at 3000 rpms. |

I'm having trouble tuning mine also my engine runs way too rich even with small jets, anyone got any ideas to overcome this problem? |

Have you checked your float level?

No I haven't I assumed it should be ok because it's a new carbi out of the box. What float setting do you guys run. |

It should be 7/16 from the air horn gasket. |

Don't "assume", in mine the floats weren't adjusted correctly and the inlet needles leaked. Either of which would cause a "rich" carburetor. |

Same here.... Mine measured out at 7/16 without the airhorn gasket. Instructions with the Carb say to hold the gasket in place and use a 7/16 drill bit to gauge float height. |

The float level was way out no where near 7/16. I set the floats and it seems to be a lot better. Bit more tuning and she should be running a bit better. Thanks fellas. |
