Went and charged battery over night for a fiver, i must of just left zed for around a week sitting in my garage, was gonna take sump off thought I would just try one more time before I replaced the plugs...fired up first time a bit sluggish but ok, bit of smoke out the back, left it to idle and warm up, all smoke cleared and idle just as she did before
Must of soaked the plugs when I switched her off last time without warming up properly and the weak battery didnt help
