I pulled the ac components. I did timing belts, water pump and plugs and wires. The car was running before doing this. I did not change timing at all from what it was. It has a weber carb on it. I can now start the car with gas fully depressed. It will only idle while like that. If I let off the car dies. I am confused on why it would do that. I assume a vacuum leak but I can't find one.
