Every time the piston comes up, it will either be the exhaust stroke or the compression stroke.
On the exhaust stroke, the exhaust valve will be open, and you will thus feel no pressure at the spark plug hole.
On the compression stroke, both valves will be closed, thus all the air must come out the plug hole, and you will FEEL that pressure as the engine is turned, assuring you that you are getting to TDC on the correct stroke for the spark.
TDC on that correct stroke can be found via Mr. Nicholson"s method.
Re: feeling the pressure... I used a circle of inner-tube rubber big enough that it wouldn"t fall through the plug hole, and put my finger over it to make a reasonable seal. It was obvious when I was on the compression stroke.
If you feel no pressure on either stroke, then you have other problems.
