Check that the correct coils are installed. I just did a FG hardtop too. The seller of the original game replaced the up coil I think, with a kicker coil. Wayyy too hard, hit the glass every time. He assured me the coil would “break in” over time....mmmk. Anyhow, confirm the coils are correct first I’d say. Then look at the coil stops, armatures and resting tabs. Post a pic of the mech.
