    What ignition system do you have points or electronic ?. Your basic logic doesn't sound correct to me, I would get the rocker arms rocking on number 4, the engine is then ready to fire on number 1. Set the crank to 8 degrees BTDC and set the dizzy so that a) the rotor arm is pointing to no 1 lead on the cap and b) the points are just opening, then start up.

    Next, you need to run the engine at about 4000 rpm and swing the dizzy so that you get maximum advance you want, probably about 32 degrees, then recheck at idle where you should have about 10 to 12 degrees before TDC. You will need an adjustable timing light to do this.

    Number 1 cylinder is at the front.
    You can set it using number 4 cylinder as you are doing it. You can't be doing too much wrong if it runs.
    Just need to swing the dizzy about to get it to run smoother.
