1976 Camaro 250 inline 6 with integrated head/intake. The previous owner bought it at an estate sale. It had been inop for some time.

He bought a new gas tank and an Amazon carb. He had the closed the choke most of the way to get it to idle.

I didn’t know what was wrong but the cheesy carb can’t help. I bought a reman Rochester like it would have had from the factory. He threw the original carb away. Because that’s what you do. It’s not like you can rebuild one for $20 (sarcasm). Of course it still has the same problem. I assumed it was a large vacuum leak. Spraying ether around the manifold to no avail. The EGR is inop but it doesn’t seem to be the leak. Its diaphragm just seems to be bad. I have isolated the brake booster. Blocked all vacuum ports except advance. Timing at 6 before. When vacuum advance is hooked up it advances what seems more than it should. Too much vacuum? The choke has to be almost closed regardless. With or without. I don’t see how the intake could leak. There are no bolts to tighten. No visible cracks. Fuel pressure seems good (Sprays everywhere when line is loose). I’m lost.

 

Scannerdanner, it's been teaching the same process a long time ago.
