Usually let it tick over and warm up 10/15 min's. Thank you for that bit of information, i will pull it out Monday/tuesday. Hopefully the wheel will be with us by then, last set of plugs were bit naffed was running rich. I hadn't tuch it since because it was running like a gem. its no good pulling them after its been sat idling it needs to have hada run so its getting fuel fed into the engine from the main jets not the slow running ones hence giving it a run down the road for the mot or something similar and then check plug colour
