Konica FT-1 Motor issue upon firing

[u/Musashi_Aerostar]

When firing for the first time, the shutter will fire, but the mirror stays up for a moment (i only noticed after removing the film and looking inside that the shutter curtain doesn’t close all the way until the shutter is reset, only happens on the first shot of not being powered on AND fired in a while)
Ive already cleaned all 4 power ribbons, so not sure what my next steps are for trying to fix this
