Have this reel disassembled. Found the problem - a very small compression spring that is mangled and in two pieces. The schematic I found for this reel is very poor quality - I can identify the spring (key #204), but it doesn't show enough detail to figure out where it belongs. Appears to fit somewhere between key # 701 (drive gear shaft assembly) and key #807 (yoked brake plate).
Anyone have a photo of that spring in its correct location? Curious - what is its' function? Seems llike an awfully fragile spring for a reel intended for some rough use ???
Gentleman from Colorado did a detailed step by step guide here, I will seek the thread for you.
post a pic of yours opened up, maybe we can tell you where it goes.
I have serviced a few of mine.
