How open should the throttle on your push mower be during normal operation?

Depends on the bar blade length for one. The Feds mandate a max blade tip speed for safety reasons.

Worked stronger at first then got weaker over time ...found carb is leaking still. I think it's running rich. Plug is on the dark side.

For mine it depends on the job it has at the time and the air temperature . Driving to the mail box when it's 90°F and mowing tall crab grass at that same temperature is a world of difference .
You can check for air flow across the ahead with your hand . A mouse can build a nest in there over night that can stop the air .

Many modern day engines on walk behind mowers don't have manual throttles, and may or may not have adjustments on the carb.
