On the flywheel are the marks FA4 or SF Adv., indicating firing point at full advance can be seen.The letters EP stand for exhaust peak and TDC indicates top dead centre for numbers 1 and 4. A cover on the near-side of the clutch pit is held by two 5/16in. nuts. Flywheel marks are visible below this cover.

If the timing chain has been removed, rotate the camshaft in running direction until No. 1 . exhaust valve is fully open—a dial indicator on the rocker shaft is the only accurate way of ensuring this. Turn the engine until the EP mark on the flywheel is inline with the pointer in the aperture. Fit the timing chain.
To time the ignition turn the engine until the FA mark registers and both valves on No. 1 are closed. FA is 7 1/2 deg. or 3/4in. before TDC. The rotor arm of the distributor should now correspond with No. 1 H. T. terminal. The ignition control should be in the fully advanced position and the pinch bolt beneath the distributor head should be slackened and the head rotated until the points are just opening.
