PLEASE HELP ME. I have a shutter button issue with my Minolta SRT-200. I recorded a video to explain the issue. Thank you in advance : https://youtu.be/uUvUTI81yEY

When you cleaned your system you snagged a small spring which holds the stop lever under tension. Looking at the SRT101 service manual which uses the exact same mechanism the spring 3067 is what you lost referencing this guide page17 Minolta SRT101 Service Manual
