How do itime a 240z Datsun?
To time a Datsun 240Z, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder number one. Next, align the timing mark on the crankshaft pulley with the TDC mark on the timing cover. Adjust the ignition timing by loosening the distributor hold-down bolt and rotating the distributor until the timing light indicates the correct advance (usually around 10-15 degrees BTDC). Finally, tighten the distributor bolt and recheck the timing to ensure it remains in the desired range.
