Fit cam pulley (needs to ne on correct timing) and belt and tension belt.
Basicly, you have to spin the crank pully to the set degrees (as quoted by the cam manufacture, or ford, on CVH usually 104 - 120 degrees, depanding on cam fitted).
Then undo vernier adj bolts, spin the cam to get No 1 inlet valve at full lift, using dial gauge.
- spin the engine to make sure belts tension'd correctly all round, and no valve to piston.
- then double check the cam dialed correctly.
- run up, get warm, and set the idle, mixture, ign timing.
