Sorry, duplicate post.

I did not see anyone mention that you have to disconnect a wire on the firewall . Then set timing to "0" after that reconnect wire that will set timing I believe the wire is brown with white strip it has a plug in it so you can disconnect it.

Need to know year of the engine, type of ignition and if computer controlled including and crank or cam sensors, throttle position sensor, etc, what manifold, carb, fuel pressure while cranking and running, type of gas being used, age of gas, type/age of all fuel lines-----------

47Fordcoupe recently purchased this car which has a 305 SBC in it. ??? hahaha. Lotys of if's to this...

What else should I explain? This is a pretty stock engine aside from a Edelbrock carb and intake, and I also explained this: "I already ruled out a harmonic balancer ring slip. Found tdc with a piston stop and made a new mark on the balancer. Installed a 1" wood carb spacer, , heat shielded the starter and solenoid, fuel pump and fuel line, installed new spark plugs/wires, new distributor rotor,coil and cap. Idle timing is set at 30* and it won't decrease without stalling."

Thank you all for your help
