Have been out for a 40 mile blast after timing side re-assemble after finding wandering woodruff key. little man with hammer may have gone but now have other issues (timing, plugs, fuel to name but a few). Took some photos of piston crowns, Any comments appreciated,. Is the small brown band at the top of bore, larger at bottom the norm. Am aware that one crown is showing quite a bit of carbon, am assuming burnt oil from guide or ring. will now attempt to post pictures and expect things to start crashing (website, laptop).
