is just what it says on the tin..
Always roll forwards (Clockwise) to find TDC dont come backwards.
So if you miss, go round again..
I would just take a spark plug out,
drop a screwy with a long shank on it in to the hole,
but not much of a angle incase it scratched or jammed.
Rocked the car in gear, until screwey comes to the top.
Mark the screwey if your unsure and watch for the next time
around and you know your there when you see the mark.
The more spark plugs you take out the less compression (Fight)
you wil have turning the crank
Just ask the Haynes questions your not sure of
