How do you set timing on Porsche 356?

To set the timing on a Porsche 356, first ensure the engine is at operating temperature and then locate the timing marks on the crankshaft pulley and the engine case. Use a timing light connected to the number one cylinder's spark plug wire, and aim the light at the timing marks while the engine is idling. Adjust the distributor by loosening its clamp and rotating it until the timing mark aligns with the specified degree (typically around 7-10 degrees BTDC for the 356). Finally, tighten the distributor clamp while ensuring the timing remains in the correct position.
