I mapped out the events in a 4-stroke, 6-cylinder engine with firing order 153624. Sure would have been easier for a 4-stroke, 4-cylinder. I was hoping that someone would know this off the top of their head. I'm focusing on pushrod positions because the engine is being reassembled.
When #1 is at TDC, only #2 exhaust and #3 intake valves are fully open (pushrods up). #4 is in a power stroke, #5 is in compression and #6 is between its exhaust and intake strokes.
If you are 180 deg. out with the flywheel ball also at the pointer, only #4 intake and #5 exhaust valves would be fully open (pushrods up). #1 would be between its exhaust and intake strokes and both pushrods would be down.
Confirmation, anyone?
