What is the correct timing setting for a 1986 VW Golf 1.8L single overhead cam?
If you have a stock distributor and know either the timing at idle or the maximum advance at a given engine speed and you have a good timing light, you will have no trouble setting timing. If not, here are some ways to get in the ball park. I already mentioned that the highest idle speed is very slightly advanced from correct. If you set it there and hear no pinging on acceleration and get good power (ha-ha), you are good. If it pings, retard it little by little until the pinging goes away. If it seems weak, advance the timing a little at a time until you hear pinging or find the engine hard to start, then retard it again.
