so just put my dual carbed intake on my 6 cyl and i fired it up it runs but it wont idle by its self if anybody can help me that woulbe be great thanks
check that the intake gasket isn't leaking. that whole ***embly can be a bear sometimes. just my 2 cents..
If the carbs are good and it ran fine before you changed to the dual carbs, I would look as theBRAIN 426 said or for some other vacuum leak.
Sounds like a va***e leak. Have the car running and spray stater fluid out side the carb. If it speeds up a little that means you have a va***e leak. The leak is ****ing in the starter fluid causing it to rev.
Squirt some oil around the manifold to head fittment and if it smokes out the exhaust you got a leak. Those ring in the head ports are a problem to seat. Iceman
