So it looks like a combination of factors...
1. I'm missing part # 9569 (washer),
2. I think have a needle that's not compatible with the seat,
3. I have a retainer that's also not compatible with the seat (looks like it' be compatible with a "screw-top" seat, not a "bolt-like-top" seat, in that it's designed with a curve (to accommodate a cylinder)).
The top of my seat looks like a bolt (not a screw, as some of the graphics I've seen in this thread look like). However, my needle looks like it'd be compatible with a "philips head" screw, in that it has 4 ridges along the cylinder. Is anyone familiar with this type of needle seat?
What do your needle, needle seat & retainer look like? Are there several variants and is it possible that I did get a needle & retainer from one variation and a needle seat from another?
