take out number 1 spark plug place thumb over hole bump engine untill you feel pressure building.
Bring the timing marks on the balancer to top dead center there you are.

I should have clarified further.

I want to make sure #1 piston is at TDC to check the mark on the HB to ensure it hasn't slipped and matches the timing cover. Usually you need to use a piston stop and a degree wheel etc. which would require the timing cover all off. I wondered if there was a simple way to find TDC on the pison through the spark plug hole without the full hassle.
