Let's look at page 59 (D section) in here. https://oljeep.com/53CjDj/53-71JeepCjDjServiceManual.pdf
After you look at page 59, you probably will never ever need all of that info in that PDF ever again!
Mr. Oil pump is driven off of the cam.
There is a slot in the end for the distributor to be rotated
Therefore the distributor can fit in one way and 180 degrees the other way----you cannot just move the slot as with a 258 or 304
You can move the slots position by snatching the oil pump out--moving the gear and reinserting it.
Lets not do that now/ yet!
Lets find TDC and see where the rotor button is pointing------
We may need to twist the distributor to meet up----or----take it out slightly and
rotate the rotor button 180 degrees to line up and still have "timing adjustment"
Send your results
Here's how to do it
This is a 4 stroke engine it takes 2 complete crankshaft revolutions to make 1 cycle.
In doing so, the timing marks will be at zero twice.
TDC only will be achieved once.
In order to find which revolution TDC is at, try this procedure.
Hide your keys (will not hand crank and start w/ no keys turned on!)/chock your wheels/ go to neutral
Remove #1 spark plug
Stick it back in , maybe 2 threads (instead of using your thumb)
Rotate the engine with a wrench or ratchet (not the starter) it's too EZ to bump it too far if you are new at this.
Clockwise as viewed from the grill.
When you hear the "hiss" coming by #1 plug-----STOP! ( a friend may be helpful to hear this at #1, the other cylinders hiss internally (usually a lot fainter) when you rotate the engine manually.
Now, we are on/ beginning the compression stroke on #1 cylinder (piston has just started coming up)
We ain't up yet!
Ever so slowly rotate the engine (cw) till your timing mark (line) lines up with zero!
STOP!!!
Bumping with the starter confuses a beginner, marks get overrun, then he mistakenly rotates on around 180 degrees from where you should be (not sayin' bad things, but if you are new to this, it's an ez mistake!)
Back to finding TDC of the engine.
OK, back to our slow-motion movements!
Now look at the rotor button.
it should be facing one of the towers on the 'stributor (or close)
.......or which ever tower you chose to be #1 (textbook position or not)
The engine/ cam/ crank don't care which one it is!
As long as you were at TDC, you placed #1 spark plug wire on "that tower" (the one that rotor is pointing to).....or make it happen
DO NOT MOVE THE CRANK---Your timing marks on the pulley and numbers below the water pump should be lined up on "0" (TDC)
We may need to twist the distributor to meet up----or----take it out slightly and
rotate the rotor button 180 degrees to line up and still have "timing adjustment"

OH I HAVE PLENTY MORE IF THIS IS NOT THE ISSUE!!!!!
I'll go back and re-read thru the skimming I did to get here.
