Oright, Yes i did have the head skimmed and the cam i took out wasent that bad. I only had it started by someone pushing down the metering flap slightly then it did run but sounded slightly rough and after about 15 seconds the revs would drop down and i would have to press the flap again slightly and the revs would shoot up and drop back down again and it will keep running but i have to stay by the flap and push it every 20 secons when the revs drop. Because of it not running properly yet i havent had chance of bedding in the cam.
