When I adusted mine I turned them anticlockwise to lower the cutter, where the manual said the other way. Also be careful I left it tilted back for around 30mins and just as I finished adjusting the cutter I noticed oil coming out the air cleaner. Lucky the oil was nice and clean from the oil change I had just done, but it took two hours to get it going again cause of the oil now in the carby and cylinder:(.I'll try and post some pics again but I'm not sure on how to do it..
