When finding TDC on the #1 cylinder, do the following to insure that you're at TDC on the compression stroke, not TDC on the exhaust stroke:

When rotating the engine, put your thumb or finger on the spark plug hole in the head, effectively sealing it. When the piston comes around to TDC, if it tries to blow your finger off of the hole, you're on the compression stroke (both valves closed). If there's not much pressure on your finger when the piston comes up (because the exhaust valve is open), then you're on the exhaust stroke.
