Question about 1993 Geo Metro
Get a strobe timing light, hook the aligator clamps to the battery and the C clamp to the #1 spark plug wire. This makes the lamp flash every time #1 plug fires. Point it at the main pully and you should see it flash and light up a mark on the pully. If you see no mark, stop the engine and look for it. Paint it white with some correction fluid, then try again. You will also need to loosen your distributor, which has two bolts holding it tight. You can tell which bolts as they have elongated holes to allow you to adjust timing. Once you see the white timing marks, (with engine warmed up) rotate the loosened distributor until the mark lines up with the 5 or 6 on the plastic timing belt cover near the pulley. This would put your timing 5 or 6 degrees advanced. I think factory is 5.5, so this should be close.
