Thanks Woody
Predictably, having pulled it apart a little, it definitely needs new crank seals at least, the bottom end was covered in gear oil. So Id just as well go the whole hog.
One more thing, the piston and bore are largely unmarked but it seems loose in the cylinder - Is that relatively normal? are they generally a bit piston-slappy?
also, the conrod has next to no up and down play but is very sloppy left to right? is that to be expected too?
