After re-reading this question, I get the feeling a further explanation might be in order -
I apologize if I'm being TOO basic - but I have seen very knowledgeable people get confused by the 4 stroke cycle. Especially if they work mostly on 2 stroke engines.
Remember what's going on for each "cycle" (the piston coming up and down twice)
1.) intake valve opens, piston moves down drawing in air/gas 2.) valves close, piston moves up compressing air/gas (compression stroke) 3.) plug fires, piston moves down (power stroke) 4.) exhaust valve opens, piston moves up pushing exhaust gasses out
Repeat until field is plowed.
So remember, the only time you want the plug to fire is right at the top of the compression stroke. And the only time you'll feel compression building in a cylinder is during the compression stroke.
Again - sorry for the overly basic engine 101 stuff, I don't mean to insult.
But it can really help to repeat it in your head as you're hand cranking the engine trying to find TDC of the compression stroke.
And I know how easy it can be to forget this basic stuff when you get to rely on timing marks all the time!

I was suppressed when I looked up the part number of the auxiliary drive shaft because for some reason the part number went through a radical change and it lost its "Basic Part Number". Ford part numbers follow the following rules. Most part numbers are in three parts. The middle part is called the
