Had a couple of spectacular backfires - sounded like a shotgun!!, but will it run, actually it did start once, ran for a few seconds then died, just like before I pulled it apart.
Plug cap is a non supressed, so no issues with the plug cap.
This bike feels like a "jona" i.e. cursed, even if it did by some quirk of fate burst into life I dont think I would ever trust it, just one of those bikes I guess, which is a real shame as I was really looking forward to riding it.
My mind is made up, I'll probably stick it on Gumtree next week.
