I spent a couple hours today working with my game. I took the glass off and tried to find as many places the ball could get hung-up and fix those areas. Fo me the ball gets hung up at locations 1-4 marked on the pic below.

I have never owned a game where I have had so many balls hung-up. I suppose that it's inexperience and the lack of play & tweaking that happened with the whitewood...or changes to the playfield after the whitewood effort. For example, at location 3 in the pic the roll-over switch arm is in a location where a ball could (and does for me) get hung up. Moving the switch about 1/8-inch to the right, or changing it's angle slightly would have probably been all that was needed to stop that from happening there.
I ended up bending a couple of guide rails (locations 2 & 3). In other areas, I couldn't see an easy solution by bending something. After I did this I played 1 game (!) and had 2 balls hung-up during Red Line Mania. I did 't know they were hung up until RLM ended and the game didn't launch another ball. I few shakes and 2 balls rolled out of the RHS of the game in places where no hang-ups had previously occurred. Ugh...I guess I'll just have to get used to this happening randomly with this game.
I also put some foam at the end of the track builder lane, as a test. I didn't remove the plastic (way too many screws), but pushed in a short piece of foam weather stripping down to the end of the lane. This has helped reduce the number of ball rejects there. When I get the inclination I'll take the plastic off and install the foam piece properly.
I also removed the gray foam behind the 3 stand-up targets and replaced it with the black stuff that is more dense. That worked well in reducing those reflected air-balls.
My Isolator was also installed backwards, so I fixed that. My serial number is HWL 3146, so at least up too that S/N the isolators were being installed incorrectly.
After I did that stuff the game played and sounds better, but that's' a lot of work to do on a brand new game.
I added 2 more cars to the playfield, using the standoff/supports I got from American Pinball. I screwed the cars to the support in addition to the Velcro like I did with 2 of the original cars previously.
