After cleaning the newly bought TAF I started playing on it and realized immediately that the kick-out hole outside the Thing box doesn't eject the ball reliably. The coil get the ball almost out of the hole, but then it falls back in again. Sometimes it get the ball out but most often it will fail to eject ~10 times and then the thing have to come and take the ball out instead.
I have cleaned the whole eject assembly and changed sleeve, but didn't help. I noticed the plastic end of the plunger have a weird "waist-line" slightly below the tip, might be it have brushed against the switch arm close by and worn the plastic? I also noticed my coil is an AE-28-1500 while the manual on ipdb.org states it should be an AE-30-2000.
I've done some googling and it appear that others having the same problem with this hole on TAF have changed their "weak" original AE-30-2000 coil with the stronger 27-1200 and get it to work fine, but it kind of feels like a hack. Shouldn't the original coil, or my current (stronger?) AE-28-1500 be enough?
Note: the pics were taken while cleaning, so the black dot on the plunger tip for example is not a hole as it looks like but dirt that I've already removed.
Looking at the pictures right now I also realized the wooden edge where the ball is supposed to go up seem to have a deep dent, meaning maybe the ball gets "stuck" against the small edge and fall back in? Perhaps I should try fill it with some quickwood.
TL;DR
Should I buy a new plunger, a new stronger coil or both?
