timing is 20 degrees before top dead center at 700 rpm on the 1800 cc engines. The timing mark is under the spare on the flywheel. Take a light and look straight down on the back of the engine to find the slot exposing the flywheel . The flywheel has a 20 degree mark on it . the block has the reference mark . There are 2 bolts one loosens slightly on the distributor so you can smoothly but with resistance turn it . Place the timing light inductive coil over the number one spark plug lead . The distributor cap has the leads marked 1 thru 4 . Timing light usually gets its power from the car battery . Start the engine and adjust the RPM to 700 using the idle adjustment screw on the throttle cable where it attaches to the carberator/ air intake , point the timing light so it shines on the flywheel and squeese the trigger . Move the distributor till the 20 Deg . mark lines up with the line on the block . tighten the distributor gently , firmly and recheck the timing . Finished

To time a 1987 Subaru GL, you need to locate the timing marks on the engine crankshaft and camshaft pulleys. Use a timing light to adjust the timing by rotating the distributor until the marks align properly, following the manufacturer's specifications for ignition timing. It's recommended to consult the vehicle's service manual for detailed instructions specific to your model.
