I have a 235 in a 55 truck. When the engine is running at idle it will make a popping noise, not a steady popping noise but a pooping noise every few seconds or so. Sounds like the engine is missing a step or something. I figured it may be a valve trying to stick?? The engine sat up for about 6 years or so. I have put a new carb, fuel pump, fuel lines, and cleaned the fuel tank. It also has a new coil, dist cap, rotor button, plugs, and plug wires. It only makes the popping noise at idle and it sounds like it is comming out of the exhaust pipe. When I rev the engine up it does not make the popping noise. What other things can cause this to happen??. Thanks for any help on this.
