I’ve determined that piston one is at/near TDC by inserting a screwdriver through spark plug hole #1. The timing marks line up. Doesn’t that mean it’s set up for the compression/power stroke and I should have the rotor pointing to plug position 1?

    When the #1 piston is at the top, you could be at TDC for #6 or #1.

    There are 2 easy ways to determine if the engine is at TDC for #1.

    As you're turning the engine while watching for the TDC mark on the crankshaft pulley, you can put your finger over the #1 spark plug hole to see if you can feel the motor trying to make compression, if it does, then engine is at TDC for #1

    Or you can watch the rocker arms for #1 through the oil filler cap hole and if the rockers don't move as you are approaching and then getting to the TDC mark, then the engine is at TDC for #1.

    If the rockers move,while approaching the TDC mark on the crankshaft, then you need to turn the engine another 360° to get the engine at TDC for #1.
