you will have to wait for him to reply as he told me how to do it last week and ittook me ages to understand
the way i think it works on a CVH is time the engine to normal then fit the belt, turn 360 degrees then turn the crank ectto the proper timing mark recomended and then losen the vernier to adjust the cam and make the cam fully open on the correct valve or whats recomended and then tighten and test lock up and your done
always do it clockwise too
but i was told how to time cossie cams and thats got 2 cams to think of, the cvh is just the one cam so the valve overlap is not adjustable
