With #1 spark plug removed, turn the engine over clockwise using the 3/4″ front crankshaft bolt.
You will see the degree marks on your front cover and you will see the timing mark on the balancer. Mark them with chalk or white-out.
While turning the engine over, put your finger/thumb over #1 spark plug hole. As the mark on the balancer approaches the marks on the front cover, if you are coming up on #1 TDC, pressure in the cylinder will push on your finger. If there’s no pressure, you’re at #6 TDC and need to crank the engine over until you see the marks coming together and you get pressure. Set the mark on the balancer to the 0 mark on the front cover.
