well, as the engine rotates clockwise, then you must either jam the cam solid & rotate the pulley clockwise, or turn the cam anticlockwise, with the pulley stationary to advance it

questions like this scare me, if you dont know which way to turn it is it really a good idea to be fiddling with it in the first place

pmsl yeah i already had it set that way just wanted to double check as it had no + or - marks, i've worked on engines before and i'm not stupid i just know that you can never be too sure so i'd rather ask. Burgo, why would it scare you? i'm the one thats spent the money on it, not you. exactly jon, was one or the other. thanks jimbo, i'll try that ;) lol
