I can't set the wheels as they are already apart plus the inlet cam wheel has moved. I need to know where I can set the cams

Billy :

You need to turn the cams as to have closed valves on the first cylinder, and balancing open valves on the fourth cylinder....the crankshaft should be turned to have the first and fourth pistons at TDC (the crankshaft pulley at mark)....And then you should put the cam pulley or sprocket on marks.

Thanks. I now need to know what the exhaust cam should be set at. Closed on no1 and open on no4? as well?

Billy :

The exhaust cam as well as the intake would have to be closed at one........and at number four you would have the balance, which means the exhaust is closing (still open) and the intake is opening.......
