lgnition Timing Inspection and Setting
1.Start the engine. Hold the engine at 3,00O rpm with
no load (A/T in S or E position, M/T in neutral) until
the radiator fan comes on, then let it idle.
Pull out the service check connector located behind
the right kick panel. Connect the BRN/WHT and BLK
terminals with the SCS short connector.
4. Adiust ignition timing, if necessary, to the follow-
ing specifications:
lgnition Timing:
16 t 2 BTDC (RED) at 75O 1 50 rpm in noutral
NOTE:
a Shift lever must be in neutral.
a All electrical systems should be turned OFF.DATA LINKCONNECTOR {3-P}NOTE: Do not attachthe jumper wire.

5. To adjust ignition timing, loosen the distributor
mounting bolts, and turn the distributor housing
counterclockwise to advance the timing, or clock-
wise to retard the timing.

Tighten the adjusting bolts and recheck the timing.
Remove the SCS short connector trom the service
check connector.

ldle Speed Inspection
Shift to neutral or Ll] and start the engine. Hold the
engine at 3,OOO rpm with no load until the radiator
fan comes on, then let it idle.
Connect a tachometer to the test tachometer con-
nector.

Distributor Top End Inspection
1.
2.
Check for rough or pitted rotor and cap tefminals.
Scrape or file oft the carbon deposits.
Smooth the rotor terminal with an oil stone or #600sandpaper i{ rough.
Check the distributor cap Jor cracks, wear, and
dSmage, lf necessary, clean or replace it.

Distributor Removal
1.
2.
Disconnect the 2-P and 8-P connectors from the dis-
tributor.
Disconnect the ignition wires from the distributor
cap.
3. Remove the distributor mounting bolts, then remove
the distributor Irom the cvlinder head.

Distributor Installation
Coat a new O-ring with engine oil, then install it.
Slip the distributor into position.
NOTE: The lugs on the end of the distributor and
its mating grooves in the camshaft end are both off-
set to eliminate the possibility ot installing the dis-
tributor 18Oo out of time.
DISTRIBUTOR END CAMSHAFT END
Install the mounting bolts and tighten them tem-
porarily.
Connect the 2-P and 8-P connectors to the dis-
tributor.

1.When reassembling the dislributor, install the distri-
butor rotor so on the shaft that it faces in the direc-
tion shown (toward the No. 1 cylindetl,
2.Align the index mark on the distributor housing with
the index mark on the end of the shaft.

ing on tho rubbq boots. Do not bend the wilos; you might
bl€ak tham inside.
1 . Check the condition of the wire terminals. lf any te.-
minal is corroded, clean it. and if it is broken or dis-
torted. reolace the wire.
IGNITION WIRE
Connect ohmmeter probes and measure resistance.
