Have one of these cars myself. The C-3 diagnostic lead is the ALDL mounted to the bottom edge of the dash just right of the steering wheel. You will need to insert a paperclip into the slot to ground terminals A and B to prevent the ECM from advancing or retarding the timing as you adjust the distributer. These are the same terminals you would ground to read the trouble codes.

How do you adjust the timing on a 1993 Geo Metro hatchback with the three cylinder engine?
This requires a timing light You're supposed to put a jumper wire between the ground terminal and the test switch terminal of the diagnostic connector plug before adjusting the timing. The connector plug is on the firewall under the hood, next to the coil. If you look at the socket straight on with the plastic catch on the left, ground is the lower right hole, test switch is right above it. Then hook up the timing light. The distributor is held in place by two bolts in adjustment slots. Rotate the distributor clockwise to retard timing, counterclockwise to advance timing.

Could someone please help how to set Ignition timing on 93 Mazda 929 3.0?
You need to set the base timing. That means you ground the No. 10 terminal in the diagnostic port to the ground terminal in the same port. The diagnostic port is just inside the driver's side fenderwell and has a plastic cover that will tilt up towards the engine with a squeeze and a pull. Usually you can see "DIAGNOSIS" imprinted right on the top. The number ten terminal is the second terminal in from the right side on the top row (standing on the driver's side facing the engine; there are two sets of two) and the ground terminal is the leftmost in the second row down. A paper clip will do fine for this purpose. Then, using a regular old-school timing light, check for your mark (a tiny line cut into the edge of the crank pulley) to be between 11 and 13 degrees BTDC (to the left of the "10" imprinted on the grey plastic timing best cover). If it isn't, loosen the adjusting bolt on the top of the distributor set the timing by rotating the distributor (to the right moves the mark to the right in vice-versa). When you remove the jumper, the engine will find it's own timing on signals from the distributor and from the Crankshaft Position Sensor behind the crank pulley to the ECM.
