Before you start the car, locate the crankshaft pulley, (lhs engine bay near the alternator). Turn the engine over, (either by cranking it over or turning over by a socket on the crank pulley bolt), until you locate a small notch in the pulley. Mark this notch with a dab of Tippex/white paint. Note also the small scale/timing indication on the cambelt housing...

Start the car and go for a drive to thoroughly warm the engine through. This will ensure that the ECU will not alter the timing due to a "cold engine"

With the car at idle verify that the speed is 700-800rpm once correct then locate the diagnostics connector...

...open the diagnostics socket and bridge together TE1 and E1

Failure to short these pins together will ensure that you do not set the ignition timing correctly!

Connect your timing gun signal lead to No 1 spark plug, carefully noting the orientation of the connecting lead (arrowed), and then connect the negative and positive to the Battery

Point the timing gun at the crank pulley and your freshly painted Tippex mark. The notch should line up at the 10 deg mark, if this is correct then job done, your timing is correctly set, if not then proceed as follows:

Locate the distributor assembly. You'll notice that the whole assembly is bolted to the block with 2 bolts. Loosen these but do not remove the bolts. Leave the bolts in place so that the whole dizzy can just be rotated by hand. Rotate the dizzy slowly until the notch aligns with the 10 deg indication on the crankshaft pulley

Carefully tighten the dizzy securing bolts and re-check the timing as it has a habit of slipping when the dizzy is re-tightened. The bolts should be torqued to 39Nm
