Quoted from Grangeomatic:
Just put a hardtop on this Flash Gordon. All is going well, but the saucer kicks out really strong now. When it goes down, it gets airborne and hits off the pop bumper cap, then sometimes bounces right back into the saucer. I can see the pop cap breaking over time. When it goes up it slaps the glass, hits off the top by the rollovers and usually bounces back into the saucer again.
Pretty sure that's not how it's supposed to work.
Any suggestions on how to reduce the power of that kickout?
Sounds like you have it 180 degrees out of phase, i.e. you got the orientation for it shooting into the upper playfield shooting to the lower playfield (and vice versa). Turn the whole assembly by 180 degrees.
