Same here! Teeny bit wobbly. Mine also leans a bit at rest a few millimeters to the right. I've studied the mechanism & there isn't a lot to the parts that hold the kicker in place. Basically a shaft that sits in a guide. My shaft is perfectly square; but I noticed that the guide that the shaft rests in is a bit rounded in each "corner" of the square & has a notch in the top for the kicker at rest. The shaft can move around in the guide due to these rounded corners from what I can tell. However, the replacement part I've found for these have the "rounded corners" built into the square guide bracket already. In the end I wonder how tight the shaft is really supposed to be within the guide anyway. If the guide were any tighter, the shaft might not move properly inside it to kick the ball. I wonder if there is any tension on the spring on the shaft itself that holds the guide upright? I've seen pictures of Shadow guides at rest & there's def a mix of leaning vs upright. Very interesting stuff!
