Don't know if this is a problem or just a thing with T2's. The top saucer hole where you collect the LHS insert awards ie. Hold bonus, extra ball etc etc, the ball more times than not will bounce out rather than lock in on my machine. I can try say 10 attempts and 7 will fail if not more. Is it an alignment problem ie level of machine or some part that needs replacing?

Do you mean the area below the skull, which pops the ball via the VUK to the ramp? 

If so, then yep, if you don't have the machine on the correct angle this can cause issues.  Also there must be a piece of foam between the wire ramp and skull.  There is a service bulletin from Williams in relation to this.

Thirdly, is the drop target going down?  If it is broken and the ball is bouncing straight off it, this may also be the cause???
