It's really not too hard. There's a pin just above the crank pulley that you line up with three marks on the crank pulley.

you can look straight down, or at a slight angle and see the pin. It just barely sticks out above the pulley

I usually take a marker or white out and make the three marks on the pulley a little more visible.

I believe the marks are, 0(tdc), 10deg, and 12deg

I usually shoot the light straight down from the top and can look right down the side of the light and see the marks.

Frequently the timing marker, or pointer has been broken off, or replaced with an ordinary bolt.

So, if this is true in your case, you have plenty of company.

I've always fine tuned my timing by ear and test driving. Too retarded the car loses power in the higher RPMS. Too advanced and it turns over slowly, pings, or runs good only in the higher RPM range.

pointer may be gone, but the lower cover will still have the numbers... usually covered in grease and oil.... spray some brake or engine cleaner just above the crank pulley and start wiping it down clean to find the numbers.... time to 10* with the jumper (e1 and t1) in.
