tips to tune up any G16 this old. 31 years old. manuals are rare.
spark plug gap at 0.028" 0.71mm
set the Distributor VR sensor gap. seen in link below.
hot engine, not cold.
set it to the timing advance value seen on the under hood sticker of the car, USA< outside USA , it is about -8Degree's. BTDC.
the steps on 89/90 are not like newer 8valve engines at all, use the 89book only. https://fixkick.com/IGN_timing/89-timing.html
then set duty cycle per same manual, see my link per above. (ISC calibration this is) and a DC volt meter can work well. 50% = 7vdc at ISC pins
and then set the idle switch closure, called TPS calibration, it really is just the idle switch closure setting for sure.
and last if ever at all,? adjust the Dashpot. screw, using above photo rules.
during all that , no electrical loads as as the FSM book states means. (no huge alternator loads in truth)
no A.C. ON. (air conditioning)
no head lamps on
no heater blower on.
no rear defrost glass heaters on.
no load we say, just engine running only load.
the screw far far low on the TB is the idle stop TV screw for dutycycle setting
the screw just behind the dashpot is just for it.
