Ted,
If you watch the valves for cyl 4. When the exhaust valve is open the pistons are driving upward. Cyl 4 is driving to exhaust and cyl 1 is getting to the firing position and is in the compression stroke.
When cyl 4 exhaust valve closes you are roughly at TDC for both Cyl 4 exhaust stroke and cyl 1 TDC compression stroke. If you continue turning the crank cyl 4 intake valve will open while cyl 1 is in the power stroke driving down after the plug has fired.
When cyl 4's exhaust valve closes just before cyl 4's intake valve opens you are at TDC on cyl 1 or just a couple of degrees before TDC cyl 1. PS... At this point the rotor should be under the distributor caps # 1 plug wire and the points should have just opened.
I hope this helps, Chet...
