I have a 67 camaro, 350.

And i think the afb carb i got with it is dead, when i try to start it, gas starts pouring out the top of the throttle linkage, now i know this isn't right, but does anyone know the exact problem???

I am buying a new carb tonight, holly 750, electric choke, vaccum advance secondary, any other suggestions???

Any help is appreciated thank you

 

Just use the new holley, you'll love it

 

Anytime gas pours out of a carb, first thing to look for is dirt stuck in an inlet needle. You have to pop the top on Carters to get at the needle. On a Holley, you can just pull needles out the top.

The 750 vacuum secondary Holley is my all time favorite carb. Suggestions: convert the secondaries from metering plate to metering block so you can change jets. Carb will be ok out of the box, but jets make tuning easier. Put a quick change kit in the secondary diaphram housing. You can buy a kit with different springs to change opening point of secondaries. Use the softest one that will not cause car to bog. Cheap made in China chrome fuel lines will flake chrome and it gets in the inlet needles. Don't use the see through plugs that replace the sight plugs on the float bowls. They give a distorted view of float level, can haze, and can break off when you get sick of them and try to remove them.

Last, buy "Holley Carburetors & Manifolds" by Fisher and Urich, published by HP Books. Excellent reference.

 

thanks for the info, it really helps, being my first classic, any knoledge is appreciated.
