Did you find any debris in the drained oil? You may have some pieces hanging out down in your sump.
I found the stud and washer in the oil pan. Stud is broke and intake threads are pretty mangled. I might have a to buy this used xl500r motor I have my eye on, but I'm hoping the head will be workable ( even though the kicker is stuck and it won't move )
I will have to make my own timing chain marks since I'm having no luck getting the piston to move to TDC, or to move at all. Maybe a piece of wood hammered into the spark plug hole will do the job
