I'm having a problem with my dad's 84 PX 200e clutch. I had it replaced and installed it myself, however it doesn't seem to separate and so I can't engage gears without slamming into them violently. I thought my cable adjustment was loose so i tightened it up to the point where the lever is ridiculously stiff yet the clutch doesn't seem to work still. Currently i have the clutch out and disassembled and noticed a space for a missing gear that I imagine would sit behind the clutch. I also know that my dad removed the oil mixing mechanisms in the 80s because they weren't the best at getting the mixture right. All other parts of the clutch and its actuation seem normal.
Should I be concerned about the missing gear? What could be wrong with my clutch that I'm just not seeing? Thanks for your advice.
