How to set the camshaft timing

The way to set up an Austin engine fitted with a chain driven camshaft is as follows.
Turn the engine until the mark on the flywheel indicates that No1 piston is at TDC
Next, turn the camshaft until the inlet valve of No1 cylinder is just commencing to rise.. The two timing gears are now in the correct position for the chain to be fitted .It will sometimes be found, however, that the chain will not engage properly with the teeth on the timing wheels when they are in this position In such case turn the camshaft back until the teeth engage, remembering that the camshaft rotates in the same direction as the crankshaft, and not in the opposite direction as with the Austin seven

In the case of the Austin Twelve, when the timing is correct, the TDC mark on the flywheel, when the inlet valve commences to lift, mat come anywhere between 3/8 of an inch before or after TDC.
