Got the shifter spring swapped out this week. That issue had apparently happened some time ago and someone had rigged up some mangled, funky spring on there to replace it and the broken one had been floating around in the bottom of the motor for a while! Can't believe that didn't end up in the pump or crank causing total havoc.
On a related note, is the oil pump drive chain normally loose like that? There's no tensioner of any sort on it. Looking at Chammymans photos, his are the same way. Seems odd to me but I guess its not been an issue?
Now waiting on my flywheel puller to arrive today so I can swap out flywheel and stator and this motor is ready for gaskets and to go back in the frame!
It's no mistake that the word "silent" and the word "listen" contain the same letters.
