I've had A few issues with mine having to do with the ball getting stuck around that upper horn. And Mr.pembertons or the good folks at Williams decision to make the playfield so diffult to service is definitely a negative for this game!
Regarding the problem with the "sticky horn" it looks like the ball is getting hung up on that gate switch. I suppose you could block that, and make it a "not so skillful" shot, maybe you could incline the game more, or, I think the best idea might be a small insert right there.. like a wedge, or like a flat triangle so the ball goes up, but it can't rest there because of the slope of the wedge... I haven't a clue how to fashion something like that, maybe UHMV or duraglide, sanded to size. Maybe just a piece of aluminum bent in a tent shape... maybe so someone has had this problem and has a more orthodox solution?
Thanks guys!!
