Ice cube getting 'stuck' at that point is often the result of too little water in the ice mold, making the cubes too small for the rake to push them out. To test for this it might be possible to squirt a little extra water into the ice mold just after a fill using a turkey baster, flower watering can, etc. If the cubes eject Ok after that, you can look into why it isn't filling sufficiently.
Most icemakers have a fill adjustment screw on the side of the front mechanism or just beneath the cover. It can be used to adjust the fill time slightly. It should however usually never need to be adjusted after the initial installation so a problem in the water supply to the fridge should be looked into if adjusting the fill timing is needed.
Common causes of incomplete fills can be due to a partially plugged sediment screen at the fridge water valve (see the image below) or more commonly, a problem with the tap used on the house water line for the fridge water supply.
Use of a 'self-piercing' saddle valve is the most common cause. Such a valve makes too small of an orifice in the water pipe which can easily get clogged with lime and scale, hampering water flow. That can also occur with any type of saddle valve if mounted on the underside of a horizontal water pipe. Only a drill-type saddle valve should be used (if not a regular plumbing tap) and only mounted on the top of a horizontal pipe or the side of a vertical pipe (see image below).
Not usually other than maybe front to back, no.the ice maker is not level, the left side being lower. Can I level the icemaker without leveling the freezer.
