I would check those internal bolts with the offset washees like you mentioned. The original crossrams were not slotted for early and late styles like these are, so it might have created a new problem no one has seen before. I don't know what the best kind of sealer to use here would be, but I'd definitely want something that gas won't eat. good luck. |

OK its all back together . What I found is the carb on the passenger side was sucking like crazy through the top , took it all apart and found that as people have said here the flaps wernt closing all the way. I loosened the scrws holding flap ard adjusted play to make close ll the way .Now when its running that carb is constantly dripping fuel.I removed bowls and floats look like they are set ok. And i still cant time it when the mark is where it should be Idle is still wat to high.. Could accelerator pump or nozzle i changed do anything? thanks.

Dripping venturi usualy means the little tiny pin holes, or one of them
that meter air into the emulsion tubes are blocked. Be sure they are clean, but never alter the size of them in any way unless you are 100000% sure of what you are doing. The emulsion tubes can be corroded or blocked also. Try the vents first. |

I got a question
Why use used carbs on a $2,000 manifold that can be destroyed with a single backfire? |

I think our Holley contact was putting you on, get your money back and get a couple new ones. Sometimes it doesn't pay to economize.

OK i think its all set . The timing was off .I removed and re-positioned the distributor . It seems like it is running fine . I timed it at 38* with an advance light to TDC with all vacuum lines plugged and removed from vac adv.Thank You all for the help. I would never have figured the flap in the carb being open so little would cause such a problem. thanks again
Now I try to figure out vac secondaries springs
