Righty then i decided to give it a good look over. Checked the oil and its BLACK (got some quantum 10-40 at home that i got from tps for cheaps. Anyway took coil packs out and tried to take the sparkies out but coldnt as i was using an ordinary socket (i know wrong tool, its what i had on hand) when i took the socket out it was covered in oil

anyway my cazan got a proper spark tool out and i took the sparkies out. Looked like they were proper old, covered in soot and they are the ngk R sparkies with single electrode not double or triple. So took everything apart. Took the rocker off, cams, chain & tentioner all look good. Might service it tomoz if i have time.
Turbo is WAAAAY down. How do you guys change it?
P.s looms like its projecto time lol.
Sorry not picies as hands were covered in oil and grease.
